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.
The role
The role involves forming technical hypotheses, designing targeted tests, analyzing system logs and low-level hardware data, and distinguishing between GPU, host, firmware, interconnect, thermal, and physical hardware failures. This is a senior systems engineering role focused on diagnosing and resolving complex hardware and platform failures in high-performance AI infrastructure.
Requirements
- Minimum 5 years of hands-on systems engineering experience across Linux, server hardware, firmware, PCIe, and GPU or high-performance computing platforms
- Extensive Linux experience, particularly using Linux as an environment for hardware debugging
- Knowledge of the Linux kernel and experience with kernel-level debugging
- Strong knowledge of modern server architecture, particularly in high-performance, GPU-based environments
- Strong knowledge of NVIDIA GPU platforms and diagnostic tooling, including nvidia-smi, XID and SXID analysis, GSP and driver behaviour, NVLink, NVSwitch, Fabric Manager, DCGM diagnostics, and NCCL testing
- Deep knowledge of PCIe, including topology, enumeration, root complexes, endpoints, switches, bridges, retimers, link speed and width, AER and DPC errors
- Experience benchmarking systems for performance, stability, power efficiency, thermal behaviour, and workload characteristics
- In depth understanding of firmware interactions across BIOS/UEFI, BMC, CPLD/FPGA, GPU firmware, NIC firmware
- Experience with low-level hardware communication and debugging using I²C, SMBus, PMBus, register maps, bit masks, byte- and word-level data, and device datasheets
- Demonstrated ability to troubleshoot complex hardware, software, and networking issues
- Experience with deep problem investigation, root cause analysis, and performance optimization
- Strong analytical and problem-solving skills with a performance-first mindset
- Scripting and automation using various languages (Python\Go)
