Highlights
- Build disaggregated AI inference pairing GPU prefill with ultra-fast decode.
- Drive time to first token, throughput, and tail latency at rack scale.
- Make a new AI serving path reliable, correct, observable, and fast.
Ideal candidate
A hands-on systems owner who thrives debugging across hardware to APIs and cares deeply about production reliability, speed, and correctness for large-scale AI inference.
Requirements
- 5+ years of software engineering experience, including ownership of complex production systems
- Experience building, operating, or optimizing production inference systems for large language models, multimodal models, or similarly demanding GPU workloads
- Strong programming ability in C++ and Python, including multithreading, concurrency, memory management, and performance-sensitive software
- Experience optimizing Mixture-of-Experts or multimodal models
- Knowledge of GPU kernel optimization, operator fusion, graph capture, attention kernels, GEMM tuning, and communication/computation overlap
- Experience with reduced-precision inference and quantization formats such as BF16, FP8, FP4, INT8, or INT4, including validation of numerical and model-quality effects
- Experience building numerical-comparison, determinism, model-validation, or performance-regression test systems
- Experience collaborating directly with accelerator vendors, framework maintainers, or open-source communities
