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.
The 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 toolingYou’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 solutionsWhat 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 teamsWhat 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-upTo apply, please connect with Jack Cole or hit easy apply today
