Job summary

Nebius is building a full-stack AI cloud platform with global reach, spanning data and model training to production deployment. We seek a Lead Software Engineer to craft tooling that sits between the network core and our cloud platform, writing code with autonomy as we grow new APAC data centers.

You'll own architecture, work hands-on, and start by shaping the team around you, scaling in APAC while collaborating with Europe.

Qualifications

• 7+ years of professional software engineering experience with broad ownership and tech-lead exposure.
• Strong coding skills and ownership mindset: ship and operate reliable services.
• Proficiency in Go or willingness to switch; Python welcomed.
• Ability to work autonomously in an early-stage environment and build from scratch.
• Willingness to stay hands-on while leading and growing a team.
• Interest in infrastructure or networking, not required to be a network expert.

Responsibilities

• Build and maintain services that automate the network lifecycle: provisioning, changes, drift detection, and verification.
• Make network changes safe and transparent: CI/CD, diffs, staged rollouts, audit trails, guardrails.
• Develop observability systems that scale across sites: telemetry, signal quality, tooling for incident investigations.
• Close gaps between network and platform by integrating data sources and exposing APIs.
• Own architecture and decisions for APAC regions, aligned with Europe teams.
• Collaborate with network engineers and SREs to turn operational pain into tooling.
• Hire and onboard the first engineers in the region, set standards, and mentor the team.

Job description

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.

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)
• Contributions to open source or experience extending/debugging OSS components in production environments
• Experience building an engineering team from scratch or launching a new engineering hub

We Expect Engineers To

• Manage large-scale projects involving multiple stakeholders across regions
• Break down complex tasks and guide both their own work and that of more junior colleagues
• Be experts in specific technologies and write high-quality code that can serve as a reference
• Assess task priority and focus on high-impact work, avoiding low-value efforts
• Have strong architectural thinking and contribute to system design
• Lead hiring in the region: define the profile, run interviews, and make hiring decisions
• Share knowledge and mentor others

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
