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 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 Equal Opportunity Statement: Nebius is an equal opportunity employer.
