Staff Site Reliability Engineer

Doghouse Recruitment; España; Remote; EUR 90,000 - 150,000; Full time

Job summary

Doghouse Recruitment’s client is seeking a Staff Site Reliability Engineer for bare-metal Linux in a datacenter-focused environment across the EU. You will own reliability end-to-end, define SLI/SLOs, run error-budget conversations, and deploy changes that reduce incidents and latency.

In a 100% remote role, you’ll work on Linux performance, kernel debugging, networking issues, and Kubernetes on bare metal.

Qualifications

• Extensive production experience in bare-metal/datacenter infrastructure, 15+ years in Linux-heavy roles.
• Experience operating large fleets of physical servers.
• Deep hands-on Linux kernel debugging and performance work.

Responsibilities

• Own end-to-end production reliability, define SLIs/SLOs, and run error-budget conversations.
• Ship changes that reduce incidents and improve latency (p95/p99).
• Build automation to kill toil and make deployments safer (canary/rollback).
• Turn observability into signal rather than noise.

Job description

Staff Site Reliability Engineer – Bare Metal Linux – Data Center – Networking

Location: 100% remote within the EU

Our client, a publicly listed AI cloud provider, is building a platform for high-throughput, compute-heavy workloads. They run 1,000+ bare-metal servers across their own datacenters, where failure modes are real, capacity is finite, and reliability needs to be engineered, not “handled”.

We’re looking for a Senior/Staff SRE to own production reliability end to end. You’ll define SLIs/SLOs, run error-budget conversations, and ship changes that reduce incidents and improve latency (p95/p99). You’ll build automation to kill toil, make deployments safer (canary/rollback), and turn observability into signal rather than noise.

This is a bare-metal environment: Linux, datacenters, physical fleets and real hardware constraints, not managed services. You’ll work close to the metal across Linux performance (CPU/memory/I/O contention), network debugging (DNS/TCP/TLS, packet loss, congestion) and Kubernetes running on bare metal. On-call is part of the job, but success is measured by how much you reduce it.

Must-haves

• Extensive, recent production experience running bare-metal / on-prem / datacenter infrastructure (not public cloud only), typically 15+ years in Linux-heavy roles


• Experience operating large fleets of physical servers, directly or as part of a team


• Deep hands-on Linux debugging and performance work at kernel level (CPU, memory, I/O, low-level behavior)


• Strong coding in Go and/or Python, beyond automation scripts. Real engineering capability is a must.


• Experience in low-latency environments, e.g. kernel tuning, CPU pinning/NUMA, kernel bypass, RDMA/InfiniBand, HFT or GPU cluster networking

Nice to have

• Kubernetes internals on bare metal: scheduler behavior, autoscaling edge cases, kubelet pressure/evictions, etcd/control plane


• InfiniBand


• Terraform, Puppet or Ansible; Docker, Helm and modern CI/CD


• Work on large-scale infrastructure powering the AI economy


• 100% remote anywhere in the EU, with competitive compensation

If you’re looking for complexity and a new place to nerd out on infrastructure optimization, we’d love to hear from you!
