Research Engineer, QC Automation

• We'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.
• Create 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
• You 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
• 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.
• Team Size: ~25 people currently, mostly full-time in-person, but some remote.
• Our team: Our team includes 4 International Olympiad medalists (IOI, ILO, IPhO), the former #1 ranked Catan player in the world, serial AI startup founders, and researchers with publications at ICLR, NeurIPS, etc.
• Company stage: We have 8 figures in funding and are scaling profitably and quickly to meet very strong demand.
• Employment: Full-time.
