## About the role

Model customization is the fastest-moving layer of the machine learning stack. Post-training has moved from supervised fine-tuning to reinforcement learning against verifiable rewards, and from single-turn tasks to agentic training where a model learns by acting in an environment over long trajectories. Each shift changes the shape of the workload. Reinforcement learning puts an inference engine inside the training loop. Found on 1752vc Careers, the job board for startup and VC roles.
