Descrizione del lavoro

Nebius in Amsterdam is seeking mid- to senior-level software engineers with deep C++ expertise to advance the YDB open-source platform. You will help evolve architecture for new hardware and optimize storage and networking across large clusters.

The role focuses on high-performance, low-latency components, memory and CPU efficiency, and cross-functional collaboration. Hybrid or EU-remote work options are available for senior candidates.

Competenze

• 5+ years of professional experience developing high-load C/C++ software.
• Experience designing and developing production-grade distributed storage systems and/or databases.
• Understanding of CPU caches, atomic operations and NUMA architectures.
• Experience with debugging and profiling tools such as perf, VTune, bpftrace and gdb.

Mansioni

• Evolve YDB’s architecture for new hardware, redesigning core components when incremental optimization is insufficient.
• QLC NVMe drives: increase storage density while controlling RAM/CPU consumption and write amplification.
• Dual 800 Gb/s network adapters: reduce CPU overhead and memory bandwidth consumption to utilize the available NIC bandwidth.
• NVIDIA GB300-based systems: ensure efficient operation on Arm-based hosts and offload storage and networking processing to BlueField DPUs.
• Support high-capacity SMR HDDs by designing data placement, sequential writes, garbage collection and recovery around zoned-write constraints.
• Develop wide erasure-coding schemes to reduce space aplimfication while maintaining durability and availability.
• Reduce recovery and rebalancing times after device outages while limiting the impact on foreground workloads.
• Prevent, detect and recover from silent data corruption across memory, networking and storage.
• Provide the system capabilities and interfaces required by fleet-wide automation so that hundreds of production clusters can be deployed, configured, upgraded, diagnosed and operated consistently.
