Senior Software Engineer (Storage Virtualization Team)
Nebius
This is a role where you'll own hard infrastructure problems from day one. Nebius is a Nasdaq-listed cloud platform built for the AI economy, and their Storage Virtualization Team is solving problems that directly impact how enterprises train and deploy models at scale. If you want to work on systems that matter—not toys—this is the move.
You'll build distributed, fault-tolerant storage systems delivering sub-millisecond latency and massive throughput. Your work spans high-performance block and filesystem storage, virtualization layers like virtio-blk and virtio-fs, and the kind of infrastructure that runs when hardware fails. This is backend engineering at the hyperscaler level.
You should have strong systems programming fundamentals, experience with distributed systems, and comfort debugging complex performance issues. Background in storage, networking, or kernel-level work is relevant. A portfolio of open-source contributions or past projects handling concurrency and fault tolerance helps.
Apply through CareerJumpShip with your resume, a brief note on why storage infrastructure interests you, and links to any relevant code. Nebius has R&D hubs across Europe, the UK, North America, and Israel—this role is remote-friendly.
