About The Position

On behalf of The Ministry of Justice, we are looking for a Senior DevOps Engineer (Inside IR35) for a 6-month contract. This is a hybrid working role based in any MOJ UK office. The Observability Platform team, part of Justice Digital and Data Science (JDDS) at the Ministry of Justice, is building a new, central observability platform from scratch. Their first customer is Cloud Platform, the Kubernetes-based hosting platform behind many Justice Digital services, with plans to expand to teams across the Office of the CTO (OCTO) and wider JDDS. The goal is to bring metrics, logs, and traces together into one consistent, secure, UK-hosted service, enabling teams to understand service behavior, spot problems early, and recover faster. As a Senior Engineer, you will help evaluate and set up core tooling, onboard the first tenant teams, and establish patterns for others to follow. You will collaborate closely with the Cloud Platform team, engineers in service teams, security colleagues, technical architects, and the product manager to make justice services more reliable and easier to run.

Requirements

• Have hands-on experience designing, building and operating observability tooling for metrics, logs and traces, such as Prometheus, Grafana, Loki, Tempo and OpenTelemetry, or commercial equivalents such as Datadog.

• Have experience operating production systems on a major public cloud provider such as AWS, Azure or GCP (we mainly work in AWS).

• Have experience building platforms used by many teams, including multi-tenancy, access control, self-service onboarding, and managing data volume, retention and cost.
• Have experience defining SLIs and SLOs, building useful dashboards, and designing alerting that reduces noise and supports effective incident response.
• Have experience using a programming or scripting language such as Python, Go or Bash to automate tasks, build integrations or extend tooling.
• Have a systematic, evidence-led approach to evaluating tools and designs, weighing cost, security, data residency and operational effort, and recording decisions clearly.
• Understand how to handle telemetry securely, including keeping personal and sensitive data out of logs and traces.
• Have experience working openly across disciplines, communicating clearly with technical and non-technical colleagues, and sharing knowledge through documentation, pairing and mentoring.
• SC Clearance is an essential requirement.
• Willing and eligible to undergo SC checks.
• Must be able to work within the UK and not Overseas.
