Job Description

We’re looking for a Site Reliability Engineer to join our SRE team - someone who thrives on solving complex production issues, understands how applications behave in the real world, and takes pride in keeping systems reliable and performant. This is not a platform engineering role. You won’t just be spinning up Kubernetes clusters or building infrastructure - you’ll be deeply involved in understanding our applications, what they do and how they operate, troubleshooting real-world issues, and working directly on improvements that impact our customers every day.

What You’ll Do

• Incident Response & Troubleshooting: Investigate and resolve incidents raised by clients, diving into logs, metrics, and application code to identify root causes.
• Application Debugging: Work across our core stack - Java, Golang, and Python - to trace and fix issues affecting reliability or performance.
• Data Fixes: Perform data investigation and fixes using Postgres.
• Operational Excellence: Patch and maintain Kubernetes clusters and other production systems.
• SRE Roadmap: Contribute to the continuous improvement of our observability, reliability, and automation initiatives.

This role is hybrid and will require regular weekly attendance at our London office.

Requirements

• Solid experience with application debugging in at least one of: Java, Golang, or Python.
• A good grasp of PostgreSQL - enough to run queries, analyse data, and perform safe fixes.
• Familiarity with Kubernetes and modern cloud platforms (AWS, GCP, or Azure).
• Understanding of incident management, observability tools (Grafana, Prometheus, etc.)
• A mindset focused on reliability, quality, and ownership.

Benefits

• Enhanced leave - 38 days inclusive of 8 UK Public Holidays
• Private Health Care including family cover
• Life Assurance - 5x salary
• Flexible working - work from home and/or in our London Office
• Employee Assistance Program
• Company Pension (Salary Sacrifice options available)
• Access to training and development
• Buy and Sell holiday scheme
• The opportunity for “work from anywhere/global mobility”
