Staff Site Reliability Engineer - Bare Metal Linux | Kubernetes | Python / Go | Remote EU
Our client is building a cloud platform for high-throughput, compute-heavy AI workloads. They operate large-scale infrastructure where failure modes are real, capacity is finite, and reliability needs to be engineered, not "handled".
We are seeking a Senior or Staff SRE who will own production reliability end-to-end for our client: define SLIs/SLOs, run error budget conversations, and ship changes that reduce incidents and improve latency (p95/p99). You will build automation to kill toil, improve deployment safety (canary/rollback), and turn observability into signal rather than noise.
This is a bare-metal environment: think Linux, data centres, physical fleets and real hardware constraints, not managed services. You will work close to the metal across Kubernetes internals (scheduling, autoscaling behaviour, kubelet pressure/evictions, etcd/control plane), Linux performance (CPU/memory/IO contention), and network debugging (DNS/TCP/TLS, packet loss, congestion). On-call is part of the job, but success is measured by how much you reduce it.
You will sit in our client's Hardware Infrastructure team and report to a team lead in Europe. They are adding nine SREs to the infrastructure organisation this year, seven in Europe and two in the US.
Must requirements
- Extensive Production Engineering experience running bare metal / on-prem / data centre infrastructure (not public cloud only)
- Deep hands-on expertise in Linux systems debugging and performance (CPU, memory, IO, kernel-level behaviours)
- Strong understanding of networking (DNS/TCP/TLS, latency, packet loss, congestion, troubleshooting under load)
- Experience with Terraform, Docker, Helm and modern CI/CD practices
- Strong coding skills in Python and/or Go, beyond automation scripting. Real engineering capability is a must
- Experience in low latency environments
If you are looking for complexity and a new place to nerd out on infrastructure optimisation, we would love to hear from you.
