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 automate QC for training data created by companies using HUD’s infrastructure. You’ll build the systems that scale quality to help us meet our continued strong demand.
ResponsibilitiesCreate QC systems based on true understanding and human judgement, without relying heavily on LLMs
Define and enforce quality standards for training data
Design experiments and metrics to grade agent outputs
Partner with data vendors to debug quality issues and diagnose agent failure modes, provide actionable feedback, and improve their data generation processes
Translate QC learnings into systems for auditing supplier-generated datasets, including sampling strategies, validation pipelines (rule-based and model-assisted), and feedback loops
Continuously integrate QC learnings into infrastructure tools and data vendor portal to reduce anomalies, inconsistencies, and edge cases
ExperienceYou may be a good fit if you have:
Proficiency in Python, Docker, and Linux environments
Strong understanding of what “good data” means and how to measure it
Genuine curiosity of different domains and great at asking questions to understand them
Built scalable data validation pipelines and automated QA/QC systems end-to-end without a fully prescribed roadmap
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
Early-stage startup experience with ability to work independently in fast-paced environments
Strong candidates may also:
Have knowledge of statistics
Have strong written and verbal communication skills for collaboration with our partners and team members across time zones
Be comfortable designing metrics, experiments, and QA/QC processes, not just executing them
Have experience with existing benchmarks and can reason about how to construct tasks in new evals
Thrive in unstructured problem spaces
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.
