I’m working on a really exciting opportunity for a Performance Engineer to join a team building high-performance AI infrastructure.
This is all about finding what’s slowing a workload down, fixing it, and proving the improvement.
You could be working across:
🚀 Distributed training
⚡ Large-scale inference
🖥️ Multi-node HPC
🔧 C++ / CUDA / Triton
📊 Profiling, bottleneck analysis and end-to-end optimisation
The team is ideally looking for someone with:
- 3+ years of whole-stack performance work
- 3+ years of systems programming in C++, CUDA or Triton
- Experience profiling complete workloads and fixing the actual bottleneck
- Experience improving a training, serving or simulation workload across nodes
📍 Cambridge, MA — hybrid 3 days/week
🌎 Remote also available across the USA & Canada
If you enjoy digging into performance problems and squeezing more out of complex systems, I’d love to hear from you.
💰 Competitive salary + benefits + meaningful early-stage equity.
