## About the role

Together AI is building the best inference infrastructure for voice applications. Our Voice AI platform powers production-grade, real-time voice agents and applications — serving speech-to-text and text-to-speech models with best-in-class latency and reliability.

## What they're looking for

- 5+ years of experience in ML engineering, with a focus on model serving, inference optimization, or ML infrastructure
- Hands-on experience with LLM serving engines (vLLM, SGLang, TensorRT-LLM, or similar) — comfortable reading and modifying engine internals, not just using APIs
- Strong proficiency in Python and PyTorch, experience with GPU profiling and optimization (CUDA, memory management, kernel-level debugging)
- Track record of shipping ML systems to production with measurable performance improvements
- Strong product sense — you think about what developers building voice apps actually need, not just what's technically interesting
- Comfort working on a small, early-stage team where you'll wear multiple hats and move fast
