Senior Backend Engineer (Java)

Location: UK (Hybrid – 1–2 days per week, Welwyn Garden City)

Permanent Role

We are looking for a Senior Java Engineer to join a fast‑growing technology organisation that is redefining how modern software platforms are built and operated. This is an opportunity to work on scalable, backend systems that underpin data‑driven, event‑based products used by customers at scale.

If you are passionate about building high‑quality backend services, enjoy taking ownership of systems in production, and want to work in a DevOps‑led environment, this role offers both technical challenge and long‑term growth.

The role

As a Senior Backend Engineer, you’ll be responsible for designing, developing, and owning backend services built primarily in Java (Spring Boot). You’ll work across the full lifecycle — from system design and development through deployment, monitoring, and ongoing optimisation in production.

The environment follows DevOps principles, meaning engineers take responsibility for the reliability, performance, and maintainability of the services they build. You’ll collaborate closely with other engineers, platform teams, and product stakeholders to ensure systems are robust, scalable, and well documented.

The platforms are event‑driven and data‑intensive, supporting real‑time processing and integrations across distributed services. You’ll be encouraged to propose improvements, influence engineering standards, and help evolve both systems and ways of working.

What you’ll be doing

Designing and developing high‑quality Java backend services, primarily using Spring Boot

Building and operating event‑driven, microservices‑based architectures

Taking ownership of services in production, including deployment, monitoring, and support

Applying CI/CD best practices to enable reliable and frequent delivery

Working with cloud infrastructure, primarily on Microsoft Azure

Using Infrastructure as Code (e.g. Terraform) or developing the capability to do so

Producing clear technical documentation to support system design and ongoing development

Collaborating with engineers, platform teams, and stakeholders to deliver scalable solutions

What we’re looking for

Several years of experience delivering backend services in Java in production environments

Strong hands‑on experience with Spring Boot and modern Java development practices

A solid understanding of distributed systems, scalability, and reliability

Experience working in a DevOps‑led environment, with ownership of live systems

Familiarity with cloud platforms (Azure preferred, others acceptable)

Exposure to CI/CD tooling such as GitHub Actions or similar

Experience working with SQL and NoSQL databases

Strong problem‑solving skills and the confidence to take ownership of technical decisions

Nice to have (but not required):

Experience with Python in backend, data, or automation contexts

Exposure to AI/ML or large language model‑based systems

Kubernetes and container orchestration experience

Tech environment

Languages: Java (primary), other JVM languages welcome; Python a plus

Frameworks: Spring Boot

Architecture: Microservices, event‑driven systems

Cloud: Microsoft Azure

Infrastructure: Terraform (IaC)

Databases: PostgreSQL and NoSQL solutions

CI/CD: GitHub Actions

Monitoring & alerting: New Relic, Splunk, xMatters (or similar)

Tools: GitHub, Jira, Zendesk

Why join

Join an organisation experiencing triple‑digit growth

Work in a multicultural, highly skilled engineering team

Genuine ownership of systems, not just feature delivery

Opportunities to upskill in DevOps, cloud, and platform engineering

Competitive compensation and benefits, including medical insurance

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

Where to advertise AI jobs UK in 2026: the specialist boards and communities that reach AI engineers, ML scientists and applied research talent in the UK. 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.

AI Jobs UK 2026: What to Expect Over the Next 3 Years

AI Jobs UK 2026: roles, salaries and the generative AI, machine learning and applied AI hiring trends shaping UK artificial intelligence careers. Artificial intelligence is creating jobs faster than the market can name them. New roles are appearing every quarter, existing titles are splitting into specialisms, and the technologies underpinning it all are evolving at a pace that makes even last year's job descriptions feel dated. For job seekers, this presents a genuinely unusual challenge. In most industries, career planning means understanding a relatively stable landscape and working out where you fit within it. In AI, the landscape itself is being redrawn in real time. The roles with the most hiring activity in 2028 may not yet have a widely agreed job title in 2026. That's not a reason to feel overwhelmed — it's a reason to get informed. The candidates who thrive in this market aren't necessarily those with the longest CVs or the most credentials. They're the ones who understand the direction of travel: which skills are gaining value, which technologies are driving employer decisions, and how the definition of an "AI job" is expanding well beyond the tech sector. This article breaks down what the UK AI jobs market is likely to look like over the next three years — covering emerging job titles, the technologies reshaping hiring, the skills employers are prioritising, and how to position yourself ahead of the curve rather than behind it.
