Contract Senior Engineer (Observability)
Rate: £750–£800 per day (Inside IR35)
Duration: 6 months
Start: 2nd March
Work Pattern: Flexible Hybrid
Wedo has partnered with a globally recognised Fortune 500 organisation to hire 2 Contract Senior Engineers (Observability). The environment is mature but complex. Over time, observability has evolved organically across multiple teams, resulting in inconsistent instrumentation, rising platform costs, and uneven signal quality. A tactical team is currently addressing technical debt but this role goes further. This is an opportunity to help define what “good” looks like. To standardise, simplify, and potentially reset how observability is designed and owned across engineering.
This is not dashboard maintenance. It’s about engineering clarity into the system.
Context
- Inconsistent instrumentation across domains
- High-cardinality data and ingestion cost challenges
- Strong existing investment in OpenTelemetry and New Relic
- A need to reduce noise without losing insight
- Engineering teams that need clearer standards and better tooling
You’ll work alongside platform and delivery teams to stabilise what exists, define standards, and shape the next iteration of the observability strategy.
What You’ll Be Doing
- Design, implement and evolve observability using OpenTelemetry (metrics, traces, logs)
- Optimise New Relic (or equivalent) with focus on ingestion, cost efficiency and signal quality
- Review and refactor existing instrumentation — reducing noise, removing unused signals, addressing high-cardinality issues
- Improve and maintain OTEL modules written in Go (Golang)
- Collaborate with Platform / DevOps teams on CI/CD, infrastructure and runtime observability
- Support incident response and post-incident analysis with structured improvements
- Help define and embed clear observability standards across services
- Translate product direction and enterprise requirements into scalable technical solutions
What They’re Looking For
- Strong software engineering background (Go, Java, or Python)
- Hands‑on OpenTelemetry in production environments
- Deep experience with New Relic (or similar APM / observability platforms)
- Strong understanding of distributed systems and microservice architectures
- Experience instrumenting systems — not just consuming dashboards
- DevOps capability: Terraform, Kubernetes, Helm, CI/CD pipelines
- Comfortable in AWS environments
- Strong stakeholder engagement skills — able to influence engineering and enterprise teams
What Success Looks Like
- Clear, consistent observability standards across services
- Reduced noise and measurable reduction in observability platform costs
- Improved signal quality and faster diagnosis of production issues
- Engineering teams confident instrumenting and operating their own services
- A sustainable observability model — not just a temporary clean‑up
