About the role

As a Senior Site Reliability Engineer on the MetalDev team, you will split your focus between production operations and reliability (60%) and engineering automation (40%). You will lead incident response, troubleshooting, root-cause analyses, and post-incident reviews while participating in an on-call rotation. In this senior role, you will write resilient Go code, build Prometheus and Grafana dashboards, and develop automated remediation workflows to reduce manual overhead across our fleet. Additionally, you will define SLOs and KPIs, improve CI/CD deployment pipelines, and create self-service tooling for Fleet Operations and Hardware engineering teams.

5+ years of experience in Site Reliability Engineering, production engineering, cloud infrastructure, or software engineering.

Working proficiency in Go with experience developing production-quality software.

Hands-on production experience with Kubernetes and containerised microservices architectures.

Experience with observability and telemetry stacks, specifically Prometheus and Grafana.

Demonstrated track record supporting production services, leading incident management, and participating in on-call rotations.

Excellent troubleshooting, analytical, and technical documentation skills.

Preferred:

Experience managing or automating bare-metal infrastructure.

Familiarity with BMCs, Redfish, or server-management technologies.

Experience building automated remediation or self-healing systems.

Familiarity with public cloud platforms such as AWS or GCP.

Wondering if you're a good fit?

We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams-even if you aren't a 100% skill or experience match.

You love to: Build automated remediation workflows and eliminate operational toil across bare-metal infrastructure.

You're curious about: Developing low-latency telemetry pipelines and scaling self-healing systems across massive data centre clusters.

You're an expert in: Production incident management, Go programming, and designing robust Kubernetes-native observability tools.
