About this role
About HUDHUD's mission is to build reliable, fair and open infrastructure for AI data. We want data to be valuable for the people who create it and trustworthy for the labs that train on it. Our team is a quickly growing group of researchers, engineers and operators building the economy that shapes what AI will become. Backed by $16M from top VCs and YC (W25), our marketplace and platform are used by startups, Fortune 500 companies and frontier labs.
About the roleWe’re looking for Research Engineers to build our synthetic data pipeline. You’ll turn domain-specific workflows into synthetic training tasks that are realistic enough to enough to teach useful behavior, structured enough to generate at scale, and difficult enough to expand model capabilities.
ResponsibilitiesWork with subject-matter experts to create synthetic tasks for training AI agents across a range of professional and technical domains
Design synthetic task generation methods that produce diverse, realistic, and learnable tasks
Build systems and tooling to mutate, validate, and improve synthetic tasks
Analyze model and agent performance on synthetic tasks to understand what the tasks are teaching and where they fail
Develop metrics to quantify and understand synthetic task diversity, realism, learnability, etc.
ExperienceYou may be a good fit if you have:
Proficiency in Python, Docker, and Linux environments
Have experience with synthetic data research methods - please elaborate in your application
Strong understanding of what “good synthetic data” means and its limitations
Built synthetic data pipelines end-to-end without a fully prescribed roadmap
Experience working on environments, evals, and benchmarks
Strong candidates may also:
Be detail-oriented and able to spot subtle inconsistencies or edge cases in synthetic data
Be able to reason from first principles about task design, scoring, and failure modes
Thrive in unstructured problem spaces
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.
Team & company detailsTeam Size: ~25 people currently, mostly full-time in-person, but some remote.
Our team: Our team includes 4 International Olympiad medalists (IOI, ILO, IPhO), serial AI startup founders, and researchers with publications at ICLR, NeurIPS, etc.
