Job Opportunity: Freelance Site Reliability Engineer (Outside IR35)




£500-550 | Remote (UK-Based) | Occasional travel to Farnborough or Hammersmith




Contract until 2026



We're hiring
two hands-on Site Reliability Engineers (SREs) to join a fast-moving platform team on a long-term contract. This role is ideal for engineers with strong coding skills who are comfortable resolving live production issues - not just escalating them, but diving into the code and fixing them directly.



This is a UK-based, fully remote position, with occasional in-person meetings in
Farnborough or
Hammersmith . The contract is
outside IR35 and runs through 2026.




Key Requirements

• Strong software engineering experience, ideally in Java (Spring Boot) and Python


• Proven background in SRE practices, including platform reliability, monitoring, and incident response


• Ability to debug and resolve issues directly in production code


• Solid experience with Kubernetes, AWS, CI/CD pipelines, and observability tools


• A proactive, collaborative approach with a strong engineering mindset

Desirable Experience

• Background in regulated or high-availability environments such as Payments or FinTech


• Understanding of data platforms or large-scale platform architecture

Why Join?

• Outside IR35


• Competitive day rate (£500-550)


• Remote-first working with occasional on-site collaboration


• Long-term contract through 2026


• Opportunity to have real impact on system reliability, performance, and code quality

This is not a passive SRE role - you'll be embedded in engineering teams, taking full ownership of production issues and resolving them at the code level. If you're a hybrid between a developer and an SRE, we'd love to hear from you.
