Applied Research Engineer

About HUD

HUD is building infrastructure to create RL training data and evals for frontier AI agents, as well as a marketplace to sell this data 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
• Cook up 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

• 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 communication skills for remote collaboration across time zones

What We Offer

• Competitive compensation
• 100% covered top-of-the-line medical, dental, and vision from Blue Shield of CA (US employees)
• Lunch and dinner when you’re in the office
• Company-wide holiday break (Christmas Eve to New Year’s Day) on top of PTO and paid holidays
• Other perks including an Equinox membership, 401k, and commuter benefits (US employees)
• Unlimited* access to tokens for ChatGPT, Claude Code, Cursor, etc.
