Member of Technical Staff, Computer-Use Agents

The Computer-Use Agent (CUA) team at Hark builds agents that use a computer effectively and efficiently to accomplish increasingly long-horizon tasks. These are the models that let Hark get real work done on a user's behalf, from a single errand to workflows that run for hours.

We're looking for engineers and researchers who are motivated to build the best computer-use agents in the world. This role demands high-quality engineering combined with genuine research ability, and the agency to investigate promising novel algorithms and approaches that will shape the next generation of computer-use agents at Hark.

You'll work collaboratively in a fast-moving, high-performance team across every aspect of training computer-use agents. We expect deep technical expertise in one or more of the following areas: data and environment engineering, agentic evals, RL post-training, and training and inference infrastructure for agents.

This is a high-ownership role on a small team. Beyond the CUA team, you'll work closely with the harness and product, pretraining, and infrastructure teams.
