Site Reliability Engineer, Model Post Training

What Thinking Machines Lab says about it

ABOUT THINKING MACHINES The mission of Thinking Machines is to build AI that extends human will and judgment. We are training frontier models with Inkling, developing Tinker to let people make models their own, and crafting interfaces that broaden human-AI communication. We believe the future worth building is human, and we're hiring people who want to build it. ABOUT THE ROLE We're looking for a Site Reliability Engineer (SRE) to drive reliability for Model Post Training end-to-end. Post-training spans several distinct workloads — supervised fine-tuning, reinforcement learning, preference optimization, and distillation — each with its own resource profile, failure signature, and tolerance for interruption or delay. You'll set the reliability strategy across all of them, not just react to what breaks. This is a senior individual-contributor role with real technical authority.
