Job description

Senior Site Reliability Engineer

Central London (Hybrid)

Up to 100k + Car Allowance & Bonus

TRIA are working with a leading hospitality client to hire a Senior SRE, where they are investing heavily in the performance, stability, and reliability of its digital platforms.

This is a hands-on leadership role - you won't just guide others, you'll be the go-to expert when systems are under pressure. You'll lead incident response, own root cause analysis, and solve performance issues like memory leaks, outages, and flaky services.
You will take ownership of the site reliability and drive that as a discipline.

Your focus will include:

• Leading incident management, post-mortems, and blameless RCAs
• Building scalable, resilient microservices with the dev teams
• Uplifting observability
• Improving alerting, monitoring, and system-level metrics
• Driving better SLOs, SLIs, and overall uptime

What you'll bring:

• Experience in high-traffic digital or eCommerce platforms
• 5+ years in SRE/DevOps roles; strong background in incident response
• Observability, automation, and infrastructure as code expertise
• Leadership skills - mentoring others or leading from the front

The stack includes Kubernetes, Terraform, AWS, Python, and modern CI/CD tools, and it's evolving.

If you understand what a good SRE practice looks like, and want to leave systems in a better place than you found them, please apply to be considered and learn more!
