Job description

I'm supporting a leading quantitative technology firm that's looking for an experienced Observability Engineer to join its Platform Engineering team.

This is a hands-on role focused on building large-scale telemetry platforms, improving Kubernetes observability, and shaping the future of OpenTelemetry across a highly technical engineering environment.

The role

• Build scalable telemetry pipelines
• Develop OpenTelemetry collectors, SDKs and exporters
• Improve Kubernetes observability and resilience
• Work closely with Platform Engineering teams to drive automation and reliability

What we're looking for

• OpenTelemetry
• Kubernetes
• AWS
• Datadog, New Relic or Dynatrace
• Terraform, Helm or ArgoCD
• Go or Python
• SRE or Platform Engineering background

This is one of the strongest observability opportunities in London for engineers who want to build the platform itself, not just consume the tooling.
