Responsibilities include defining reliability targets, driving improvements across network and data centers, incident leadership, observability, and safe change workflows, while collaborating with APAC and European

Qualifications

• 7+ years of experience in SRE/infrastructure engineering with leadership or tech-lead responsibilities.
• Strong Linux fundamentals and debugging skills for complex systems.
• Solid networking knowledge including failure domains and performance.
• Hands-on experience operating highly available systems and improving them.
• Ability to write/maintain automation in Go or Python.
• Experience with modern infrastructure tooling (IaC, CI/CD, containers).
• Ability to work independently in a startup/early-stage environment.

Responsibilities

• Define and own reliability targets (SLIs/SLOs, availability, error budgets).
• Drive reliability improvements across APAC network and data centers.
• Own incident response, lead investigations, and implement long-term fixes.
• Build and evolve observability with metrics, logs, traces, alerts.
• Design safe change workflows with CI/CD, canaries, rollbacks, audits.

Job description

About Nebius:

Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

The Role

We're looking for a Lead Site Reliability Engineer to build and run the fundamental part of Nebius in APAC: the Network, the infrastructure everything else depends on. We are at the early stage of our APAC expansion, so this is a hands-on role. You will define reliability targets, write automation and handle incidents yourself, with a high degree of independence from the European teams. As the region grows, you will build and lead the local SRE team.

Your responsibilities will include:

• Define and own reliability goals for network services and critical paths in the region (SLIs/SLOs, availability targets, error budgets where it makes sense)
• Drive reliability improvements across the whole APAC network: not only services, but also site readiness, inter-site connectivity (DCI), and operational standards for new data centers
• Own incident response for your areas, lead investigations/postmortems, and turn failures into durable fixes (not repeated firefighting); set up on-call and incident management practices for the region
• 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 in APAC and Europe to embed operability into designs and keep operations practical and fast
• Hire, onboard and mentor the first SREs in the region and set the engineering bar for the team
• Coordinate with European teams on handoffs and coverage across time zones

We expect you to have:

• 7+ years of experience in SRE / infrastructure engineering, including experience leading a team or acting as a technical lead with broad ownership of production systems
• 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
• Ability to work independently in an early-stage environment and to build processes and a team from scratch
• Willingness to stay hands-on while leading and growing a team

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 (routing/flow telemetry, regression detection at scale)
• Knowledge of the APAC network landscape (carriers, IX, regional connectivity and regulatory specifics)

Benefits & Perks:

• Competitive compensation
• Career growth and learning opportunities
• Flexibility and ownership
• Collaborative and innovative culture
• Opportunity to work on impactful AI projects
• International environment and talented teams

What's it like to work at Nebius:

Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI
