Python Developer - Observability Engineering

London | Hybrid | Perm

I’m working with a leading quantitative research and trading firm looking to expand their Observability Engineering team.

This team sits at the centre of engineering productivity, owning the systems that allow teams to produce, move and consume telemetry at scale. The focus is on making observability seamless across a large, high-performance environment handling cloud-level volumes of data.

The role

• Build and extend observability tooling across telemetry pipelines and backend systems

• Develop and maintain OpenTelemetry collectors, SDKs and exporters

• Define and promote “golden paths” for instrumentation across a wide range of services

• Work closely with engineering and research teams to improve visibility and developer experience

• Scale and optimise telemetry systems handling large volumes of real-time data

• Improve incident response through better coverage and monitoring

What they’re looking for

• Expert-level Python development with a focus on backend systems

• Experience designing and building scalable, distributed systems

• Exposure to Kubernetes and cloud-native environments

• Familiarity with observability tooling such as Prometheus, Grafana, OpenTelemetry

• Experience with DevOps tooling (Terraform, ArgoCD, Helm, Jenkins)

• Interest in improving developer experience and working closely with end users

Environment

• Engineering-led culture focused on long-term thinking and technical depth

• Large-scale systems supporting research and trading workflows

• Close collaboration with engineers and researchers across the business

• Opportunity to shape observability standards across a complex platform
