Are you an experienced Software Engineer who thrives on solving real-world problems with cutting-edge technology?

This is an opportunity to join a talented engineering team building advanced, real-time software systems used in safety-critical environments worldwide. You'll be working at the intersection of enterprise software, IoT, and data-driven decision-making; developing solutions that genuinely make a difference.

Why this role is exciting

This isn't just another enterprise software role.

You'll be working on a sophisticated platform that connects physical devices (IoT) with real-time data processing, delivering actionable insights through modern web applications. The systems you help build are deployed globally and play a vital role in protecting people, infrastructure, and national security.

Engineers here consistently highlight exposure to multiple Kubernetes environments (on-prem, cloud, VM-based), working across diverse customer use cases with unique technical challenges, the chance to experiment with new tools, architectures, and AI integrations, and a broad technical landscape spanning microservices, real-time systems, and distributed architectures.

About You - What makes you a great fit

  • We're looking for a technical expert who can lead and inspire.
  • Strong background in Object Oriented Programming with knowledge of C++, Python or similar.
  • Recent experience in TypeScript / JavaScript.
  • Deep experience with distributed systems, microservices, and APIs.
  • Solid understanding of connectivity (TCP/IP, device communication, telemetry).
  • Experience working with Linux environments and Kubernetes.
  • Ability to communicate confidently with both engineers and senior stakeholders.
  • Proven experience leading teams including remote and offshore collaboration.
  • A STEM degree is required, reflecting the level of technical depth and problem-solving involved.

Tech environment

Kubernetes across on-prem, cloud, and hybrid environments. Microservices architecture with real-time data processing. IoT integrations and telemetry pipelines. Modern web applications (TypeScript / JavaScript). CI/CD, DevOps, and infrastructure as code. Emerging work around AI integration and intelligent features.

Why join

Work on meaningful, real-world problems with global impact. Gain exposure to a broad and evolving tech stack. Be part of a team that values innovation, experimentation, and learning. Play a key role in delivering complex solutions to high-profile customers. Collaborate with a highly skilled, mission-driven engineering team.

Where to Advertise AI Jobs in the UK (2026 Guide)

Advertising AI jobs in the UK requires a different approach to most technical hiring. The candidate pool is small, highly informed and in demand across multiple sectors simultaneously. General job boards reach a broad audience but lack the specificity that AI professionals expect — and the filtering mechanisms they rely on. Specialist platforms, direct outreach and academic channels each serve a different part of the market. This guide, published by ArtificialIntelligenceJobs.co.uk, covers where to advertise AI roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about time-to-hire across different role types.

New AI Employers to Watch in 2026: UK and Global Companies Reshaping AI Careers

The artificial intelligence job market in the UK is evolving at an extraordinary pace. With record-breaking investment, government backing, and a surge in enterprise adoption, the landscape of AI employers is shifting rapidly. For candidates exploring opportunities on ArtificialIntelligenceJobs.co.uk, understanding who is hiring next is just as important as understanding what skills are in demand. In this article, we explore the new and emerging AI employers to watch in 2026, focusing on organisations that have recently secured funding, won major contracts, or expanded their UK footprint. From cutting-edge startups to global giants doubling down on Britain, these companies represent the next wave of AI career opportunities.

How Many AI Tools Do You Need to Know to Get an AI Job?

If you are job hunting in AI right now it can feel like you are drowning in tools. Every week there is a new framework, a new “must-learn” platform or a new productivity app that everyone on LinkedIn seems to be using. The result is predictable: job seekers panic-learn a long list of tools without actually getting better at delivering outcomes. Here is the truth most hiring managers will quietly agree with. They do not hire you because you know 27 tools. They hire you because you can solve a problem, communicate trade-offs, ship something reliable and improve it with feedback. Tools matter, but only in service of outcomes. So how many AI tools do you actually need to know? For most AI job seekers: fewer than you think. You need a tight core toolkit plus a role-specific layer. Everything else is optional. This guide breaks it down clearly, gives you a simple framework to choose what to learn and shows you how to present your toolset on your CV, portfolio and interviews.
