Software Engineer in Network Infrastructure
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 Software Engineer to build software that makes network operations safe, scalable, and boring — even as we launch new data centers 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.
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
- Collaborate closely with network engineers and SREs to turn real operational pain into product-quality tooling
We expect you to have:
- 5+ years of professional software engineering experience (or equivalent practical background)
- 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)
-
You don’t have to be 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
We expect Engineers to:
- Manage large-scale projects involving multiple stakeholders
- 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
- Be involved in hiring and actively contribute to interviews
- Be willing to 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
