• 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
