Job description

Nebius is building a full-stack AI cloud platform with global infrastructure. This role is a Lead Site Reliability Engineer responsible for building and operating network infrastructure in the APAC region during early expansion, combining hands-on SRE work with team leadership as the region grows.

What You'll Do

• Define and own reliability goals for network services and critical paths in APAC region, including SLIs/SLOs and availability targets
• Drive reliability improvements across APAC network infrastructure including site readiness, inter-site connectivity (DCI), and operational standards for new data centers
• Own incident response for network areas, lead investigations and postmortems, establish on-call and incident management practices
• Build and evolve observability infrastructure: actionable metrics, logs, traces, alerting, and faster debug loops
• Design safer change workflows including automation, CI/CD, test environments, canarying, rollbacks, and auditability for network changes
• Hire, onboard, and mentor the first SREs in the region and establish engineering standards
• Work closely with network engineers and platform teams across APAC and Europe to embed operability into designs

What You Need

• 7+ years of experience in SRE or infrastructure engineering, including team leadership or technical lead role with broad production system ownership
• Strong production Linux fundamentals and 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)
• Hands-on experience operating high-availability systems and improving them over time
• Ability to write and maintain software and automation (Go or Python preferred)
• Experience with modern infrastructure tooling including IaC, CI/CD, and container platforms
• Ability to work independently in early-stage environment and build processes and team from scratch

Nice to Have

• Experience with high-throughput traffic processing such as load balancers, tunneling/decapsulation, NAT64, or datapath-heavy systems
• Low-level networking performance and debug background including eBPF, XDP, DPDK, perf, ftrace, or kernel networking internals
• Experience building network-safe delivery pipelines with testing labs, staged rollouts, automated verification, and drift detection
• Background with large-scale network observability and telemetry including routing/flow telemetry and regression detection at scale
• Knowledge of APAC network landscape including carriers, internet exchanges, regional connectivity, and regulatory specifics
