About the Job

Requirements

Seven or more 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 an ownership mindset, with the ability to ship and operate reliable services.
Proficiency in Go or readiness to switch; Python is also welcome, and other languages may be useful for open-source debugging and 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.
Interest in infrastructure and/or networking; expertise in networking is not required.
Ability to manage large-scale projects involving multiple stakeholders across regions.
Ability to break down complex tasks and guide one's own work and that of more junior colleagues.
Expertise in specific technologies and ability to write high-quality code that can serve as a reference.
Ability to assess task priority and focus on high-impact work while avoiding low-value efforts.
Strong architectural thinking and ability to contribute to system design.
Ability to lead regional hiring by defining profiles, running interviews, and making hiring decisions.
Ability to share knowledge and mentor others.
Applicants must be authorized to work in the country in which they apply and provide proof of employment eligibility as a condition of hire.

Responsibilities

Build and maintain services and tooling that automate the network lifecycle, including day-zero provisioning, day-N changes, drift detection, and operational verification.
Make network changes safe and transparent through CI/CD workflows, diff and review tooling, staged rollouts and rollbacks, audit trails, and guardrails.
Develop observability systems that scale across many sites, including telemetry pipelines, signal quality, and tools that shorten incident investigations.
Close last-mile gaps between the network and platform by integrating source-of-truth data, exposing APIs, and building reliable automation.
Own architecture and technical decisions for the APAC area and align them with European teams.
Collaborate with network engineers and site reliability engineers to turn operational pain points into product-quality tooling.
Hire and onboard the first engineers in the region, set code-quality and engineering standards, and mentor the team.

Desired Qualifications

Background in networking, such as experience as a network engineer, CCNP or networking education, or data-center networking exposure, or a strong interest in networking and demonstrated ability to learn quickly.
Experience building automation or infrastructure tooling, including CI/CD, infrastructure as code, testing or staging environments, or network-as-code workflows.
Low-level networking or datapath experience, including eBPF/XDP, DPDK, kernel networking, or traffic-processing systems.
Experience designing high-load services and observability platforms, including metrics, logs, traces, alerting, or regression detection.
Contributions to open source or experience extending or debugging open-source components in production environments.
Experience building an engineering team from scratch or launching a new engineering hub.

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 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

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

About the Company

Nebius

Runs GPU clouds for AI training and deployment

Nebius runs an AI cloud for developers, researchers, and enterprises that train models and put them into production. Its AI Cloud combines GPU computing, storage, networking, and managed services, while Token Factory runs models through an API so teams do not manage the underlying servers. Customers rent computing and storage at usage rates or reserve capacity, choosing resources that fit short experiments or sustained production workloads. Beyond the cloud, the group owns Avride, which develops autonomous vehicles and delivery robots, and TripleTen, which teaches technical skills for people changing careers. The publicly listed group is headquartered in Amsterdam, Netherlands.

Company size: 1,001-5,000
Company stage: IPO
