Boston · Hybrid · Staff · Full-time · Posted Aug 26, 2026
About the job
Build and maintain inference systems and reproducible benchmark suites, port models across runtimes and hardware, and verify partner implementations.
What you'll do
- Design benchmark suites for inference performance, model quality, and knowledge evaluation across hardware targets.
- Evaluate partner solutions against benchmarks, identify gaps, and communicate findings.
- Port models across runtimes and frameworks, verify correctness, and extend the inference engine layer.
What they ask for
- Hands-on experience modifying internals of at least one inference framework, such as llama.cpp, ONNX Runtime, or MLX.
- Experience designing and building benchmarking pipelines, including methodology, validation, and reproducibility.
- Strong C++ and Python in performance-sensitive contexts.
- Understanding of inference fundamentals, including quantization, decoding strategies, and memory layout.
Nice to have
- Experience porting models across runtimes and verifying numerical correctness; technical validation or evaluation with external partners or clients.
- Familiarity with edge inference targets and their constraints.
