Site Reliability Engineer in Network Infrastructure

The Role

We’re looking for a Site Reliability Engineer to help build and run the fundamental part of Nebius - the Network - the infrastructure everything else depends on. This is an engineering-first SRE role: you’ll set clear reliability targets, build the tooling and automation to meet them, and make the network safer to operate as we scale quickly.

Your responsibilities will include:

Define and own reliability goals for network services and critical paths (SLIs/SLOs, availability targets, error budgets where it makes sense)

Drive reliability improvements across the whole network: not only services, but also site readiness, inter-site connectivity (DCI), and operational standards

Own incident response for your areas, lead investigations/postmortems, and turn failures into durable fixes (not repeated firefighting)

Build and evolve observability: actionable metrics/logs/traces, alerting, and faster debug loops during and after incidents

Design safer change workflows: automation, CI/CD, test/staging environments, canarying, rollbacks, and auditability for network changes

Work closely with network engineers and platform teams to embed operability into designs and keep operations practical and fast

We expect you to have:

Strong production Linux fundamentals and a structured approach to debugging complex systems

Solid understanding of networking basics and how real networks fail (control plane vs data plane, latency/loss, failure domains, etc.)

Hands-on experience operating high-availability systems and improving them over time (not just “keeping lights on”)

Ability to write and maintain software/automation (Go is common for us; Python is also welcome)

Experience with modern infrastructure tooling (e.g., IaC, CI/CD, container platforms) and comfort automating operational workflows

It will be an added bonus if you have:

Experience with high-throughput traffic processing: load balancers, tunneling/decap, NAT64, or similar datapath-heavy systems

Low-level networking performance/debug background (eBPF/XDP, DPDK, perf/ftrace, kernel networking internals)

Experience building network-safe delivery pipelines (testing labs, staged rollouts, automated verification, drift detection)

Background with large-scale network observability/telemetry (e.g., routing/flow telemetry, regression detection at scale)

Benefits & Perks:

Career growth and learning opportunities
Flexibility and ownership
Collaborative and innovative culture
Opportunity to work on impactful AI projects
