Infrastructure Site Reliability Engineer

Role Overview

Nebius is hiring an Infrastructure Site Reliability Engineer (Network SRE / NetSRE) to help build and run the network layer of its AI cloud platform. This is an engineering-first SRE role focused on defining reliability targets, automating improvements, and making the network safer to operate as Nebius scales.

Responsibilities

• Define and own network reliability goals for network services and critical paths using SLIs/SLOs, availability targets, and error budgets.
• Drive reliability improvements across the whole network, including:
  • service reliability
  • site readiness
  • inter-site connectivity (DCI)
  • operational standards
• Own incident response for your areas:
  • lead investigations and postmortems
  • convert failures into durable fixes (reduce repeat incidents)
• Build and evolve observability with actionable metrics/logs/traces, alerting, and faster debug loops.
• Design safer change workflows using automation, CI/CD, test/staging, canarying, rollbacks, and auditability for network changes.
• Partner with network engineers and platform teams to embed operability into designs and keep operations fast and practical.

Requirements

• Strong production Linux fundamentals and a structured approach to debugging complex systems.
• Solid networking fundamentals and understanding how real networks fail (e.g., control plane vs data plane, latency/loss, failure domains).
• Hands-on experience operating high-availability systems and improving them over time.
• Ability to write and maintain software/automation (Go is common; Python is welcome).
• Experience with modern infrastructure tooling such as IaC, CI/CD, and container platforms, plus comfort automating operational workflows.

Nice to Have

• High-throughput traffic processing experience (e.g., 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).
• Large-scale network observability/telemetry experience (routing/flow telemetry, regression detection at scale).

Compensation

• Base compensation range: $179,500–$224,300 USD (plus benefits).
