Senior Software Engineer (DevSecOps)

Senior Software Engineer (DevSecOps)

Contract | Inside IR35 | Up to £580/day | Full-time | North Yorkshire (1 day per week on-site, increasing from September)

You will join a global IT consultancy delivering digital transformation to a well-established financial services organisation. You will be an experienced Senior Software Engineer with a strong DevSecOps background to join an engineering enablement function on an initial contract running to the end of December 2026.

This is a hands-on role at the centre of modernising how software is built, delivered, and operated. You will work within a squad environment, driving adoption of Golden Path patterns, progressive delivery practices, and secure-by-design principles - with a clear focus on measurable outcomes.

The role

You will take ownership of the full delivery life cycle: from pipeline design and environment architecture through to release-linked observability and incident readiness. Day to day, you can expect to be shipping small, frequent changes using trunk-based development and feature flags, embedding security and quality gates directly into CI, and working with colleagues across Release, QE, and Environments to ensure every deployment is traceable, auditable, and safe.

Alongside the technical work, you will mentor engineers, contribute to communities of practice, and help the wider team move faster without sacrificing resilience.

What you will bring

• Advanced CI/CD experience, including progressive delivery techniques such as canary releases, blue/green deployments, and automated rollback
• Solid grasp of secure-by-design practices: SAST, SCA, DAST, IaC scanning, SBOM, WAF configuration, and pipeline attestations
• Experience building and managing ephemeral, production-like environments with data-on-demand capability
• Strong observability skills - tracing, metrics, logs, SLO/error budget management, and deployment annotations
• Familiarity with DORA metrics and a track record of removing flow constraints at squad level
• Confidence with shift-left testing: contract, performance, resilience, and security tests in CI
• Proficiency in at least one modern language/runtime and cloud-native architecture

The detail

• Contract to 31 December 2026
• Rate: up to £580 per day, inside IR35
• One day per week on-site in North Yorkshire, with travel expected to increase from September
• BPSS clearance required prior to start
