Research Engineer

Job description

## **About the Role** As a Research Engineer at Metis, you’ll work on building the next generation of autonomous post-training systems that leverage our Mantis platform. You’ll operate at the intersection of cutting-edge ML research and scalable engineering, designing, implementing, and deploying algorithms that improve how AI agents learn from feedback, synthetic data, and real-world interactions. You’ll move seamlessly between papers and production, leading large-scale experiments, creating optimized training pipelines, and helping shape the future of post-training autonomy. You’ll have significant ownership, high compute budgets, and the mandate to push the state of the art in applied reinforcement and preference optimization. ## **What You'll Do** - Research and help build an autonomous post-training agent leveraging the Mantis platform - Design and execute large-scale experiments on synthetic data generation and algorithmic architecture - Develop and refine methods for reinforcement learning, reward modeling, and human feedback integration - Collaborate cross-functionally with Core and Platform Engineering to deploy and evaluate models in production settings - Publish or contribute to leading-edge research in the post-training domain - Use tooling and compute efficiently to iterate on experimental pipelines and accelerate research velocity ## **Requirements** - Deep experience in machine learning, preferably reinforcement learning, post-training, or alignment research - Demonstrated research contributions; ideally published papers (ICML, NeurIPS) or public implementations - Strong proficiency in Python and ML frameworks (PyTorch, JAX, or TensorFlow) - Comfort with distributed training, high-throughput data pipelines, and large-scale experiment management - Ability to reason independently, formulate hypotheses, and run experiments from idea → insight → product impact ## **Compensation & Benefits** - Base: $200,000–$1,000,000 - Significant Equity - Full medical, dental, and vision - Wellness & L&D stipend - Equinox membership - Breakfast, lunch, and dinner provided (Unlimited Doordash) - $25,000 housing stipend ## **About Metis** Metis helps enterprises and labs build the most reliable AI agents by leveraging post-training. Our platform enables the creation, improvement, and deployment of the most capable frontier agents designed for rigorous, real-world workflows. **Momentum** - 0 → six-figure monthly revenue in the last six weeks - Working with several Fortune 500 enterprises & frontier AI labs - Growing 150%+ MoM **Backed by** Y Combinator, CRV, and executives from OpenAI, Google, Mercor, NVIDIA, and others.
