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 backed by Y Combinator, 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.

Due to high volume, we may not actively respond to every application, but feel free to contact us at recruiting@hud.so or elsewhere if we missed your application!
