Senior Applied Research Engineer

Role description

Role Overview

The OpenPipe team at CoreWeave is building tools to help agents learn from experience. This is a critical step to make agents reliable enough to perform long tasks autonomously, in the same way human employees are. We're systematically identifying and solving the major bottlenecks between today's tech and those future self-improving agents.

What You Will Do

You will be expected to generate and investigate research ideas towards solving the remaining obstacles to continuous learning in production. You will work with the broader OpenPipe team to validate these research directions across real customer tasks.

Why It Might Be a Fit

We're looking for strong engineers with great taste. The most important qualification by far is that you learn fast and can ship. This role will inevitably involve a lot of learning on the job; we're building this airplane as we fly it.

Requirements

• Bachelor's, Master's, or PhD degree in Computer Science, Machine Learning, Robotics, or a related technical field.
• 4+ years of experience in machine learning, or a PhD with 2+ years of relevant industry experience, with a strong focus on model training.
• Strong programming skills in Python and hands on experience with modern ML frameworks such as PyTorch or JAX.
• Strong understanding of LLM post-training techniques, including supervised fine-tuning, reinforcement learning, and on-policy distillation.
• Experience developing, evaluating, and deploying machine learning models in production environments.
• Strong research and problem solving skills, with the ability to work effectively in ambiguous, fast moving environments.
