Staff Software engineer - Network infrastructure - APAC

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 Software Engineer to build software that makes network operations safe, scalable, and boring, as we launch new data centers in APAC and expand fast. This is not a "write scripts for configs" role: you'll build the tooling and services that sit between the network core (switches/ports/VLANs, traffic processors) and the cloud platform on top, using open source where it fits and building the missing pieces where it doesn't. At this stage of our APAC growth you will be hands-on: writing code, making architectural decisions and owning your area end to end, with real autonomy. Then you will grow the local engineering team around you.

Your responsibilities will include

Build and maintain services and tooling that automate the network lifecycle: day-0 provisioning, day-N changes, drift detection, and operational verification

Make network changes safe and transparent: CI/CD workflows, diff/review tooling, staged rollouts/rollbacks, audit trails, and guardrails

Develop observability systems that scale across many sites: telemetry pipelines, signal quality, and tooling that shortens incident investigations

Close "last mile" gaps between the network and the platform: integrate source-of-truth data, expose APIs, and build reliable automation around it

Own architecture and technical decisions for your area in APAC, and align them with the European teams

Collaborate closely with network engineers and SREs to turn real operational pain into product-quality tooling

Hire and onboard the first engineers in the region, set code quality and engineering standards, and mentor the team

We expect you to have

7+ years of professional software engineering experience (or equivalent practical background), including experience as a tech lead or team lead with broad ownership

Strong coding skills and ownership mindset: you can ship and operate reliable services

Proficiency in Go or readiness to switch; Python is also welcome (other languages can be useful for OSS debugging/fixes)

Ability to work autonomously in an early-stage environment, make decisions with incomplete information, and build processes from scratch

Willingness to stay hands-on while leading and growing a team

You don't have to be a Network expert, but we expect you to have interest in infrastructure and/or network

It will be an added bonus if you have

Background in networking (ex-network engineer, CCNP/education, DC networking exposure) or strong interest and proven ability to learn fast

Experience building automation/infra tooling: CI/CD, IaC, testing/staging environments, or "network-as-code" style workflows

Low-level networking / datapath experience: eBPF/XDP, DPDK, kernel networking, traffic processing systems

Experience designing high-load services and observability platforms (metrics/logs/traces, alerting, regression detection)
