Research Engineer, Agentic AI Evals

About HUD

HUD (YC W25) is developing agentic evals for Computer Use Agents (CUAs) that browse the web. Our CUA Evals framework is the first comprehensive evaluation tool for CUAs.

Our Mission: People don't actually know if AI agents are working. To make AI agents work in the real world, we need detailed evals for a huge range of tasks.

We're funded by Y Combinator and a16z, and work closely with frontier AI labs to provide agent evaluation infrastructure at scale.

About the role

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

Responsibilities

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

• Create custom CUA datasets/evaluation pipelines - likely later as we're focusing on existing evals for the short term.

Experience

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

You may be a good fit if you:

• Have hands-on experience with LLM evaluation frameworks and methodologies

• Have contributed to evaluation harnesses (EleutherAI, Inspect, or similar)

• Built custom evaluation pipelines or datasets

• Worked with agentic or multimodal AI evaluation systems

We prioritise contributions that show quality and quantity, such as building out large, high-quality eval datasets.

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

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.

Team & Company Details

• Team Size: ~5-10 people currently, looking to hire 2-3 additional people (though we judge case-by-case - could be zero or a lot more depending on candidates).

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

Logistics

• Employment: Fulltime preferred, but we're willing to consider internship offers.

• Location: Remote-friendly, but if you’re in the San Francisco Bay Area, 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. For part-time/contract/internship arrangements, we'll work fully remote (which makes things simpler anyway).

• Timeline: Applications are rolling. The process should involve 1-2 interviews and take less than a week.
