Senior Software Engineer (Full Stack – Java) — SC Cleared

My client is a specialist software consultancy delivering bespoke solutions to solve complex operational problems for Central Government customers. As their team grows, they're looking for an experienced Full Stack Engineer to join a live delivery team working on mission-critical systems used by government caseworkers and citizens.

The role

You'll work full lifecycle — from requirements and architecture through to delivery, support, and maintenance — on a Java, TypeScript and React stack, deployed across AWS and Azure. You'll be based out of one of the client's UK offices (choose your own office/home balance under their hybrid policy), with roughly fortnightly in-person time with the end client.

Depending on experience, there's real scope to grow into technical leadership — owning architecture decisions, mentoring engineers, and managing client relationships directly.

What you'll be doing

Designing, building, and testing full-stack solutions using Java (backend) and React/TypeScript (frontend)

Building and maintaining CI pipelines in GitLab, with a strong focus on code quality and security

Deploying and operating systems across AWS and Azure

Working directly with government stakeholders to translate operational needs into technical solutions

Depending on seniority: leading design decisions, mentoring junior engineers, and owning client relationships

What we're looking for

Comfortable working across both AWS and Azure

Consultancy background is a plus but not essential — they care more about your delivery track record

Genuinely enjoy working directly with clients and translating ambiguous requirements into shipped software

Security clearance — please read before applying

This role requires active SC clearance or eligible to obtain. Please only apply if you are eligible (British passport holder with 5 years of continuous UK residency) and willing to undergo vetting.

Flexitime and a genuinely flexible hybrid policy — no mandated office days beyond client visits

A dedicated Career Coach, not just a line manager, focused on your development

Regular socials, an annual summer party in London, and company away days

Onsite lunch and drinks allowances

My client is proud to be an equal opportunities and Disability Confident employer, committed to reasonable adjustments throughout recruitment.
