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 Senior Backend Engineer to join our Storage Virtualization Team, building a distributed, fault-tolerant storage system for Nebius’ hyperscaler cloud. You’ll work on high-performance block and filesystem storage that delivers sub-millisecond latency, millions of IOPS and terabytes per second of throughput, even in the face of hardware failures.
What You’ll Work On:
- Virtualization: virtio-blk and virtio-fs, QEMU and vhost-user, performance-critical I/O paths
- Networking: high-throughput VM-to-storage transport over TCP and RoCEv2 (RDMA)
- Storage systems: replication, consensus, self-healing, and data migration
What We Expect:
- 6+ years of professional software engineering experience
- Strong knowledge of C++
- Solid understanding of algorithms and data structures
- Basic knowledge of operating system internals (I/O, memory, scheduling)
- Ability to write reliable, maintainable code and debug complex systems
- Team-oriented mindset and fluency in English
We conduct coding interviews as part of the process.
