The Short Answer

Security clearance AI jobs are roles in artificial intelligence, machine learning and data science that require UK government security vetting — most commonly Security Check (SC) or Developed Vetting (DV) clearance. They exist primarily in the defence, intelligence, government technology and critical national infrastructure sectors. Employers typically sponsor clearance for eligible candidates; you do not need to already hold it to apply. SC-cleared AI roles pay £70,000–£110,000 base salary, while DV-cleared roles frequently exceed £120,000. Major employers include BAE Systems Applied Intelligence, Mind Foundry, Palantir Technologies, DSTL and Leidos. Clearance is administered by the UK Security Vetting (UKSV) agency and SC processing typically takes two to six months.


If you are an AI professional in the UK — or an aspiring one — you have almost certainly noticed a growing category of roles sitting just slightly out of reach: positions marked SC Cleared, DV Cleared, or Must hold or be eligible for UK Security Clearance. These are security clearance AI jobs, and they represent one of the most financially rewarding, intellectually demanding, and strategically important corners of the UK artificial intelligence market.

This guide explains everything you need to know — what security clearance means for AI professionals, which companies are hiring, what roles are available, how much they pay, and how you go about obtaining clearance if you do not already hold it.


What Are Security Clearance AI Jobs?

Security clearance AI jobs are roles in artificial intelligence, machine learning and data science that require the candidate to hold — or be eligible to obtain — a level of UK government security vetting. These roles exist primarily in the defence, intelligence, government technology and critical national infrastructure sectors.

The work itself spans the full spectrum of modern AI: building large language model applications for intelligence analysis, developing computer vision systems for surveillance and reconnaissance, creating autonomous decision-support tools for military operations, applying machine learning to signals intelligence, and designing AI safety and assurance frameworks for high-consequence environments.

What makes these roles distinct is not just the subject matter — it is the access. Cleared AI professionals work with classified datasets, sensitive government infrastructure, and strategic capabilities that are never exposed to the general market. The problems are harder, the stakes are higher, and the compensation reflects both.


Types of UK Security Clearance Relevant to AI Professionals

Understanding the clearance landscape is essential before you start applying. The UK uses several tiers of vetting, managed by the UK Security Vetting (UKSV) agency.

Baseline Personnel Security Standard (BPSS) is not formal vetting — it is a pre-employment check covering identity, right to work, employment history and a basic criminal record check. Many AI roles with government-adjacent contractors only require BPSS, making them accessible to a wide candidate pool.

Counter-Terrorist Check (CTC) is a step above BPSS, required where a role gives access to information or infrastructure that could be exploited by terrorist organisations. Some AI roles at airports, border control or critical utilities fall under CTC.

Security Check (SC) is the most commonly required clearance in the defence and government technology sector. SC clearance involves a criminal record check, financial vetting, and a review of overseas connections and personal history. The majority of cleared AI roles you will encounter — at defence primes, MoD-adjacent contractors and intelligence-adjacent consultancies — require SC clearance. Processing typically takes between two and six months.

Developed Vetting (DV) is the highest standard of UK personnel security vetting. DV clearance is required for roles involving access to Top Secret material and is essential for work in GCHQ, MI5, MI6 and the most sensitive areas of DSTL and MoD. The vetting process is thorough and can take considerably longer — often six months or more — and includes in-depth interviews. DV-cleared AI engineers and scientists command a significant salary premium.

Important: Most cleared roles do not require you to already hold clearance on application. Employers will often sponsor the vetting process for the right candidate. What you do need, in most cases, is British nationality or a long-established residency record. Some roles require sole UK nationality, particularly at the DV level.


The Companies Hiring for Security Clearance AI Jobs in the UK

The UK's cleared AI employment market is more diverse than many candidates realise. It is not limited to household defence names — it spans deep tech spinouts, boutique consultancies, national laboratories and government bodies.

Mind Foundry is one of the most exciting names in this space. Born out of the University of Oxford's Machine Learning Research Group, Mind Foundry develops AI platforms specifically designed for high-stakes, high-consequence environments — including defence and national security. Their work focuses on trustworthy AI: building systems that can be understood, audited and relied upon in environments where an incorrect decision carries serious consequences. For AI engineers and ML scientists who want to work at the frontier of responsible AI in a national security context, Mind Foundry represents a genuinely differentiated employer. Many of their roles require or lead to SC clearance.

Palantir Technologies operates significant programmes for the UK government and MoD. Their Foundry and AIP platforms are deployed across defence, public health and law enforcement, and the engineering teams working on those programmes are often required to hold SC or DV clearance. Palantir roles in the UK tend to be well-compensated and technically challenging, with heavy emphasis on data integration, ontology design, and increasingly on LLM-powered workflows for government users.

BAE Systems Applied Intelligence is one of the largest employers of cleared AI talent in the UK. Their cyber, intelligence and data analytics divisions employ large teams of machine learning engineers, data scientists and NLP specialists working on everything from threat detection systems to AI-assisted signals intelligence tooling. The sheer scale of BAE's cleared programmes means regular openings at all levels of seniority.

DSTL (Defence Science and Technology Laboratory) is the UK government's own science and technology organisation, sitting within the MoD. DSTL employs AI researchers, data scientists and software engineers directly — meaning you become a civil servant rather than a contractor. The trade-off is slightly lower market-rate salaries offset by exceptional job security, meaningful work, and access to genuinely novel problems in autonomous systems, human-machine teaming and AI safety for defence.

Rolls-Royce Defence increasingly requires AI and data science capability for predictive maintenance, digital twin development and autonomous systems research. Their cleared engineering teams work alongside MoD programmes on some of the UK's most significant aerospace and naval platforms.

Frazer-Nash Consultancy, Leidos, SAIC, Serco and Sopra Steria all maintain cleared AI and data science practices delivering programmes to UK government departments. These consultancies often have a more accessible entry point for candidates seeking their first cleared role, since they work across multiple clients and have ongoing need for cleared talent at various seniority levels.

Beyond these established names, a new generation of deep tech companies — including quantum computing firms, autonomous systems startups and AI safety organisations — are increasingly engaging with the UK defence and intelligence community, creating a growing pipeline of cleared roles that sit at the intersection of cutting-edge research and national security application.


What Roles Are Available?

The range of AI roles requiring or offering security clearance is broader than most candidates expect:

Machine Learning Engineer (SC Cleared): Building, deploying and maintaining ML pipelines for defence or intelligence systems. Often involves working with restricted datasets and unusual constraints around explainability and model auditability.

NLP / Large Language Model Engineer (SC/DV Cleared): Developing and fine-tuning language models for intelligence analysis, document processing, information extraction and automated reporting in classified environments.

Computer Vision Engineer (SC Cleared): Working on object detection, scene understanding and image analysis systems for surveillance, reconnaissance and situational awareness applications.

Data Scientist (SC Cleared): Applying statistical and ML methods to classified datasets — often involving sensor fusion, anomaly detection, or behavioural analytics.

AI Safety and Assurance Engineer: Increasingly in demand as the MoD and intelligence agencies grapple with deploying AI systems responsibly. Involves developing testing frameworks, red-teaming models, and working to standards like the MoD's AI Safety Framework.

Research Scientist (DV Cleared): Senior roles at organisations like DSTL or intelligence-adjacent research labs, contributing to long-horizon capability development in autonomous systems, reinforcement learning or multi-agent systems.

AI Programme Manager / Technical Lead (SC/DV Cleared): Leading cleared AI programmes for government clients, requiring both technical credibility and programme delivery experience.


How Much Do Cleared AI Jobs Pay?

Security clearance commands a genuine premium in the UK AI job market. The uplift varies by clearance level and role type, but as a general guide:

  • SC Cleared AI Engineer / Data Scientist: £70,000–£110,000 base salary, with contract day rates often running from £500–£800 per day

  • DV Cleared ML Engineer / Senior AI Scientist: £90,000–£140,000 base, with contract rates frequently exceeding £900–£1,100 per day

  • Active DV with specialist skills (LLMs, autonomous systems, AI safety): Outlier rates above £1,200 per day are achievable in a competitive market

Day rate contracting is particularly common in the cleared sector because many cleared programmes are funded on project-by-project cycles rather than permanent headcount. For AI professionals with strong Python, MLOps and modern deep learning skills, transitioning into cleared contracting is one of the more effective ways to significantly increase earnings in the short term.


How to Get UK Security Clearance as an AI Professional

The single most important thing to understand is that you cannot self-apply for UK security clearance. Clearance must be sponsored by an employer — typically one that holds a contract requiring access to protectively marked government material.

The practical pathway for most candidates looks like this:

  1. Apply for roles that sponsor clearance. Many cleared employers — particularly the larger defence primes and consultancies — will explicitly state they will sponsor clearance for the right candidate. Prioritise these when building your pipeline.

  1. Ensure you meet the eligibility baseline. For SC clearance, you typically need to have been resident in the UK for at least five of the last ten years. For DV, it is usually ten of the last ten years, and sole British nationality is often required for the most sensitive programmes.

  1. Complete the vetting questionnaire honestly and thoroughly. The vetting process involves disclosing overseas travel, foreign contacts, financial history and personal relationships. Incomplete or inaccurate disclosures are the most common cause of clearance delays or refusals — not the content of the disclosures themselves.

  1. Be patient. SC clearance typically takes two to six months. DV clearance can take longer. Many employers will allow you to begin work on lower-classification tasks while your clearance is processed.

  1. Maintain your clearance once granted. Clearance must be renewed periodically and can be revoked if circumstances change. Annual self-reporting of significant changes — new foreign contacts, overseas travel, financial difficulties — is part of the ongoing obligation.


Why Security Clearance AI Jobs Matter for the UK

The UK government has made AI capability a strategic priority. The AI Opportunities Action Plan, published by the Department for Science, Innovation and Technology (DSIT) in January 2025, committed significant public investment to AI infrastructure and identified defence and national security as priority deployment areas. The MoD's Defence AI Strategy explicitly identifies the need to develop sovereign AI capability, and DSTL — the government's own science and technology laboratory — has publicly committed to expanding its AI research headcount. According to the Alan Turing Institute, the UK is among the top three countries globally for AI research output, creating a strong domestic talent base that the defence sector is actively competing to access.

This is not a niche procurement backwater — it is a multi-billion pound national investment programme that requires thousands of cleared AI professionals to execute.

For candidates, that means the pipeline of cleared AI roles is growing, not shrinking. The skills in highest demand — LLM engineering, MLOps, AI safety, computer vision — map almost perfectly onto the modern AI skill set that the commercial market is also competing for. Cleared AI professionals are, in effect, operating in two talent markets simultaneously, with leverage in both.


Finding Security Clearance AI Jobs in the UK

The most effective channels for finding cleared AI roles differ from the standard job search playbook. Many cleared positions are not publicly advertised — they circulate through cleared recruitment networks, defence-specialist agencies, and direct employer outreach.

For publicly listed roles, specialist job boards focused on the UK artificial intelligence market — such as artificialintelligencejobs.co.uk — aggregate opportunities from the full range of employers in this space, including those operating at the cleared end of the market. Searching specifically for terms like SC cleared AI engineer, DV cleared machine learning, or security cleared data scientist within a specialist AI job board will surface relevant roles far more efficiently than a general job site search.

Engaging directly with cleared employers is also worth prioritising. Companies like Mind Foundry, BAE Systems Applied Intelligence and DSTL maintain talent communities and regularly attend university careers events — particularly at institutions with strong AI research outputs.


Frequently Asked Questions: Security Clearance AI Jobs UK

Do I need to already hold security clearance to apply for cleared AI jobs? No. The majority of employers — particularly the large defence primes and government technology consultancies — will sponsor eligible candidates through the vetting process. What matters is that you meet the residency and nationality eligibility requirements. Roles that require existing clearance will say so explicitly, typically because the programme timeline cannot accommodate a vetting wait.

How long does UK security clearance take for AI professionals? SC (Security Check) clearance typically takes between two and six months from the point of submission. DV (Developed Vetting) clearance takes longer — often six to twelve months — due to the depth of the vetting process, which includes in-person interviews. Processing times can vary based on the complexity of your personal history and current UKSV workload.

Can non-UK nationals get security clearance for AI jobs? It depends on the clearance level and the specific role. SC clearance does not strictly require British nationality, but you must generally have been resident in the UK for at least five of the last ten years and have no disqualifying overseas connections. DV clearance is significantly more restrictive and most DV-level roles require sole British nationality. Dual nationals may be considered on a case-by-case basis but face a more complex vetting process.

What is the salary premium for security-cleared AI roles? Cleared AI roles command a meaningful premium over equivalent commercial roles, reflecting the restricted candidate pool and specialist nature of the work. SC-cleared AI engineers and data scientists typically earn 15–25% above comparable non-cleared salaries. DV-cleared professionals — particularly those with LLM, autonomous systems or AI safety skills — can command premiums of 30–40% or higher, especially in the contracting market where DV day rates frequently exceed £1,000 per day.

What AI skills are most in demand for cleared roles? Python, MLOps, and machine learning fundamentals remain the baseline requirements. Beyond that, the skills attracting the strongest cleared demand in 2026 are: large language model engineering and fine-tuning, computer vision (particularly object detection and scene understanding), AI safety and assurance, reinforcement learning for autonomous systems, and data engineering for complex multi-source pipelines. Explainability and model auditability skills are particularly valued in defence contexts, where AI systems must meet accountability standards.

Which companies hire the most cleared AI professionals in the UK? The highest-volume employers of cleared AI talent in the UK are BAE Systems Applied Intelligence, DSTL, Leidos, Serco, and Sopra Steria. For more specialist or research-oriented cleared roles, organisations including Mind Foundry, Palantir Technologies, Frazer-Nash Consultancy and SAIC are significant employers. GCHQ, MI5, and the National Cyber Security Centre (NCSC) also employ AI professionals at the DV level, typically through direct government recruitment.

Is cleared AI work available outside London? Yes, and more so than in most tech sectors. DSTL is headquartered in Porton Down, Wiltshire. BAE Systems Applied Intelligence has significant cleared operations in Guildford, Farnborough and Bristol. Many cleared consultancies operate from regional offices to be near MoD sites. Cheltenham (GCHQ), Portsmouth (Navy Command), and Corsham (Defence Infrastructure) are all significant locations for cleared AI work. Remote working is limited compared to the commercial sector — the nature of working with classified material typically requires on-site presence.

Where is the best place to search for security clearance AI jobs in the UK? Specialist AI job boards such as artificialintelligencejobs.co.uk aggregate cleared roles alongside the broader UK AI market and allow targeted searching by clearance level and role type. Cleared-specific recruitment agencies — including Venquis, Sopra Steria Recruitment, and defence-specialist arms of larger agencies — also carry roles that are not publicly listed. Direct employer career pages for BAE Systems, DSTL, Leidos and Mind Foundry are worth monitoring for roles that go live without wide distribution.


Summary: Is a Cleared AI Role Right for You?

Security clearance AI jobs are not for everyone — the vetting process takes time, the eligibility requirements are real, and some candidates will find the constraints of working with classified material too limiting creatively. But for UK-based AI professionals who are eligible, they represent a significant career and financial opportunity: higher compensation, more complex problems, greater job security, and the knowledge that your work is contributing directly to national capability.
