Why work at Nebius
Nebius is leading a new era in cloud computing to serve the global AI economy. We create the tools and resources our customers need to solve real-world challenges and transform industries, without massive infrastructure costs or the need to build large in-house AI/ML teams. Our employees work at the cutting edge of AI cloud infrastructure alongside some of the most experienced and innovative leaders and engineers in the field.
Where we work
Headquartered in Amsterdam and listed on Nasdaq, Nebius has a global footprint with R&D hubs across Europe, North America, and Israel. The team of over 800 employees includes more than 400 highly skilled engineers with deep expertise across hardware and software engineering, as well as an in-house AI R&D team.
We’re looking for a Network Software Engineer (NetSWE / NetDev) 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
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
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
What we offer
We’re growing and expanding our products every day. If you’re up to the challenge and are excited about AI and ML as much as we are, join us!
