Research Engineer, Agentic AI Evals

HUD (YC W25) does RL and evaluations for frontier AI agents. Our HUD agentic RL platform is used by frontier labs, Fortune 500 companies and startups. We have grown revenue and raised funding from YC, A16Z and other leading VCs to scale fast.

We're looking for a research engineer to help build out task configs and environments for evaluation datasets on HUD's CUA evaluation framework.

• Build out environments for HUD's CUA evaluation datasets, including evals for safety redteaming, general business tasks, long-horizon agentic tasks etc.

• Deliver custom CUA datasets and evaluation pipelines requested by clients

• Contribute to improving the HUD evaluation harness, depending on your interests, skills, and current organizational priorities. (Optional, but highly valued!)

Technical Skills

• Proficiency in Python, Docker, and Linux environments

• React experience for frontend development

• Production-level software development experience preferred

• Strong technical aptitude and demonstrated problem-solving ability

Strong candidates may have:

• Startup experience in early-stage technology companies with ability to work independently in fast-paced environments

• Strong communication skills for remote collaboration across time zones

• Familiarity with current AI tools and LLM capabilities

• Understanding of safety and alignment considerations in AI systems

• Evidence of rapid learning and adaptability in technical environments (e.g. programming competitions)

• Have hands-on experience with or contributed to LLM evaluation frameworks (EleutherAI, Inspect, or similar)

• Built custom evaluation pipelines or datasets

• Worked with agentic or multimodal AI evaluation systems

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.

• Creating and solving challenging competitive programming problem-sets

• Curating large high-quality datasets, especially for research and evaluation of multimodal AI agents

• Designing complex, functional fullstack applications. Bonus points if they have users / adopters.

We prioritise contributions that show quality and quantity, such as building out large, high-quality datasets. Imagine making about ~10 small puzzles in mock web environments a day.

• Team Size: ~15 people currently, mostly full-time in-person, but some remote.

• Our team: Our team includes 4 international Olympiad medallists (IOI, ILO, IPhO), serial AI startup founders, and researchers with publications at ICLR, NeurIPS etc

• Company stage: We have received $2 million in seed funding, plus very strong demand and revenue growth beyond that. We are scaling profitably and fast to meet demand.

• Employment: Fulltime preferred, but willing to consider part-time/internship arrangements for exceptional candidates.

• Location: Fully remote-friendly. We already have several fulltime, 100% remote hires. But if you’re in the San Francisco Bay Area or Singapore, we do have an office you can work together in. We do prefer applicants who can show up to meetings in Pacific Time (UTC-7:00/8:00) or China/Singapore Time (UTC +8:00).

• Visa Sponsorship: We provide support for relocation and visas for strong full-time candidates to USA or Singapore. For part-time/contract/internship arrangements, we'll work fully remote (which makes things simpler anyway).

• Timeline: Applications are rolling. The process should involve 1 initial call, 1 five-hour take-home assignment and 1 paid, weeklong work trial before final offer.

• You will have unlimited access* to API credits for leading providers like OpenAI, Anthropic, Gemini, Cursor etc. *By unlimited, we mean no one on our token usage leaderboard has ever hit a limit. So we have no idea what the limit is.
