Job Description

About the role 

We are looking for a Software Engineer to join the Observability team at [Employer hidden]

Our team’s goal is to empower teams within [Employer hidden] to move fast and resolve issues as soon as possible by providing a set of observability tools that meet their needs. The team is responsible for a vast observability estate - covering metrics, logs, traces, alerts and profiles. 

In this role, you'll own the centralised observability configuration used by hundreds of product services, to ensure a standardised and seamless observability experience for every engineer at [Employer hidden].

How we work

We believe in programmatic implementation, peer-reviewed code, and automation. We’re looking for an engineer who enjoys the challenge of managing a high-scale environment where a single configuration change can impact hundreds of services. You’ll work closely with the wider platform tribe to ensure our observability estate is robust, secure, cost-efficient and developer-friendly.

What will you be working on?

  • Own the centralised observability configuration (otel), used by hundreds of product services at [Employer hidden] to ensure standardised and reliable telemetry across the company.
  • Contribute to evolve our observability tooling, built on open-source projects such as Grafana and Elasticsearch, to provide the best experience for engineers at [Employer hidden].
  • Collaborate with engineering teams across [Employer hidden] to improve their observability experience and help them get the most out of our tools.
  • Manage the configuration of a vast observability estate - covering metrics, logs, traces, alerts and profiling - by implementing automation and efficiencies, ensuring reliability and supporting our mission-critical services.

What do you need?

We are fully aware that it is uncommon for a candidate to have all skills required and we fully support everyone in learning new skills with us. So if you have some of those listed below and are eager to learn more we do want to hear from you!

  • Software engineering experience in Java, Go, or Python, with a focus on writing clean, maintainable code.
  • You have used observability tools like the LGTM or ELK stack and are interested in the engineering challenges of managing telemetry data.
  • You understand the basics of instrumentation of applications (OpenTelemetry).
  • You understand microservices and how a change in a central system propagates through a distributed environment.
  • You understand the importance of availability and are eager to learn the ropes of supporting high-scale, mission-critical infrastructure.
  • Growth mindset: you enjoy the intersection of software and systems and are excited to build tools that other developers love to use.
