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
• 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:

• Be detail-oriented and able to spot subtle inconsistencies or edge cases in data
• 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
• 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.
