Research Engineer, Infrastructure

As a Member of Technical Staff, Infrastructure in Harvey Research, you’ll build the systems that power how we adapt and improve leading open-weight models for legal work.

We recently post-trained our first model built for legal work, and we’re now building the team to scale up our post-training efforts. You’ll own the infrastructure behind that effort: distributed training, RL rollout systems, the environments where models learn to use tools and complete complex legal workflows, and the internal systems the team uses to manage data, run evals, and launch and track training jobs. You’ll help decide what we build, what we adopt, and how the pieces fit together.
