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 an Applied Research Engineer to own implementation. Our data buyers and sellers often have time-sensitive asks such as troubleshooting and running evals or cleaning data at scale. You'll take the lead on diagnosing ambiguous technical problems and resolving them. This work is broad and hands-on - the right fit is a strong generalist AI engineer who can move quickly and wants to work closely with frontier AI labs and data vendors.

Responsibilities

Own technical deployment requests from frontier AI labs, data vendors, and internal teams from triage to completion
Ask the right questions to clarify ambiguous asks and identify what actually needs to be done
Build tools and one-off pipelines to solve urgent customer or partner problems
Coordinate with research and GTM teams to unblock deployments
Balance speed and quality in situations where customers need fast turnaround and the path is not fully specified
Document recurring issues and turn repeated manual work into reusable tools or processes

Experience

You may be a good fit if you have:

Proficiency in Python, Docker, and Linux environments
Experience working on benchmarks and evals - you can reason about what makes a task realistic, a rubric reliable, an environment usable, and a trajectory useful for RL training
Strong debugging instincts across code, data, and environments
Demonstrated ability to operate independently in ambiguous situations without a fully prescribed roadmap
Strong judgment about when to move fast, when to escalate, and when correctness or security requires extra care
Comfort working directly with technical customers, vendors, or cross-functional internal teams

Strong Candidates May Also Have

Experience in applied research engineering or forward-deployed engineering
Experience handling urgent production, customer, or deployment issues
Early-stage startup experience with ability to work independently in fast-paced environments
Strong communication skills for remote collaboration across time zones

We prioritize technical aptitude and learning potential over years of experience. Motivated candidates are encouraged to apply even if they don't meet all criteria.
