About HUD
HUD is building infrastructure to create RL training data and evals for frontier AI agents, as well as a marketplace to sell these to frontier labs through the HUD marketplace. Our platform is used by frontier labs, Fortune 500 companies, and startups. We’ve raised $16M from top VCs and were YC W25.
About the role
We’re looking for a Lead Research Engineer, Data Quality to own how HUD measures, improves, and scales the quality of training data for frontier agents. You’ll lead the data quality team in building the systems that evaluate thousands of tasks across RL environments, synthetic data, benchmarks, and domain-specific workflows.
Responsibilities
-
Lead HUD’s data quality strategy including building QC systems, defining and enforcing quality standards, and designing experiments to grade agent outputs
-
Develop new methods for validating synthetic data at scale, such as failure-mode analysis, task mutation checks, and trajectory auditing
-
Partner with research engineers, domain experts, and data vendors to diagnose quality issues and improve data generation workflows
-
Turn qualitative research insights into production systems, internal tools, dashboards, validation pipelines, and feedback loops
-
Help build internal research taste around what makes agent training data actually useful, not just superficially correct
-
Mentor other research engineers to maintain a high bar for technical rigor, clarity, and execution speed
Experience
You may be a good fit if you have:
-
Advanced proficiency in Python, Docker, and Linux environments
