Senior Performance & Infrastructure Engineer HPC

The organization

Our client operates one of the largest GPU infrastructures in the world 100000 GPUs. Their infrastructure doubles in size every year. Were looking for engineers who love getting deep into Linux systems pushing hardware and software to their limits and making the worlds fastest AI and HPC workloads run even faster

The role

Youll join a small senior team that works between the hardware and Linux OS layers solving performance problems that affect tens of thousands of GPUs. This is hands-on high-impact engineering where microsecond gains matter and every optimization is felt at global scale.

What youll do

• Trace profile tune and optimize Linux kernel & subsystems (CPU scheduling memory management networking stack) for GPU clusters and InfiniBand fabrics

• Troubleshoot and resolve complex performance bottlenecks

• Integrate and validate new GPU hardware & infra (KVM/QEMU PCIe devices Kubernetes)

• Improve monitoring alerting and automation for large-scale distributed systems

• Occasionally assist customers in optimizing workloads

Your profile

Key requirements (non-negotiable):

• Solid Linux internals knowledge with kernel tracing profiling and tuning experience (eg. perf ftrace eBPF sysctl kgdb etc.)

• Excellent programming skills C or C system-level code with a good grasp of data structures & algorithms

• Experience in performance optimization (eg. high-load/high-throughput low-latency low-jitter memory bypasses zero-copy lock-free synchronization across large-scale clusters etc.)

• Scripting or development skills in Go Python or similar

Nice-to-haves (not key):

• Large-scale clusters (GPU or CPU)

• Virtualization stacks (KVM/QEMU) Slurm Kubernetes

• Deep learning frameworks (eg. PyTortch Tensorflow...)

• GPU-specific stack (eg. CUDA NCCL....)

This is for you if you

Love solving deep technical challenges care about performance downto the microsecond and want to work on infrastructure that pushes the limits of whats possible.

Whats offered

• Salary: up to 160k 25% bonus.

• Flexible working arrangements.

• A dynamic and collaborative work environment that values initiative and innovation.

• Location: Amsterdam or full-remote from anywhere within the EU/EER
