Description

You will work on a distributed, fault-tolerant storage system for Nebius' cloud, building high-performance block and filesystem storage with sub-millisecond latency and millions of IOPS.

Requirements

• 6+ years professional software engineering experience
• Strong knowledge of C++
• Solid understanding of algorithms and data structures
• Basic knowledge of OS internals (I/O, memory, scheduling)
• Ability to write reliable, maintainable code and debug complex systems

Responsibilities

• Develop virtualization components: virtio-blk, virtio-fs, QEMU, vhost-user
• Implement high-throughput VM-to-storage transport over TCP and RoCEv2 (RDMA)
• Build replication, consensus, self-healing, and data migration features
• Ensure performance-critical I/O paths meet latency and throughput targets
