This is an exceptional opportunity to join a market-leading software house undergoing a major cloud transformation. As their Site Reliability Engineer, you’ll play a critical role in ensuring system reliability, scalability, and performance across both AWS and Azure environments. This is your opportunity to lead cloud-native transformation and embed SRE best practices into engineering at scale.

What you’ll be doing as their Site Reliability Engineer:

You’ll be the go-to expert for designing and maintaining resilient, automated, and observable infrastructure systems. Working cross-functionally with software engineering and architecture teams, you’ll:

• Engineer highly available, reliable platforms across AWS & Azure using Kubernetes, Helm, Terraform, and cloud-native services.
• Drive infrastructure automation, build and evolve infrastructure as code (Terraform, etc.), and CI/CD pipelines to reduce toil and accelerate deployment frequency.
• Build observability into everything—own monitoring, alerting, and incident response to minimize MTTR and improve system health.
• Champion SRE culture and reliability-focused engineering—help shape sustainable engineering practices, SLAs, SLOs, and error budgets.
• Contribute across the stack with flexibility in tooling—experience with Python, Go, or TypeScript is a bonus.
• Collaborate on cloud strategy and architectural decisions, influencing how the company scales across global infrastructure.

What’s in it for you?

• Competitive salary up to £90k
• Fully Remote working
• Private medical and dental insurance
• 25 days annual leave + bank holidays
• R&D and personal training budgets
• And much more...

This is an incredibly rare chance for a seasoned, high-performing SRE to leave your mark on high-impact transformation projects in a business that’s truly committed to doing things the right way.
