About the role

Responsibilities

  • Lead HUD’s data quality strategy including building QC systems, defining and enforcing quality standards, and designing experiments to grade agent outputs
  • Develop new methods for validating synthetic data at scale, such as failure-mode analysis, task mutation checks, and trajectory auditing
  • Partner with research engineers, domain experts, and data vendors to diagnose quality issues and improve data generation workflows
  • Turn qualitative research insights into production systems, internal tools, dashboards, validation pipelines, and feedback loops
  • Help build internal research taste around what makes agent training data actually useful, not just superficially correct
  • Mentor other research engineers to maintain a high bar for technical rigor, clarity, and execution speed

Requirements

  • Advanced proficiency in Python, Docker, and Linux environments
  • Deep intuition for data quality - you can reason about what makes tasks realistic, learnable, diverse, reliable, and useful for training
  • Experience building QC systems, evals, benchmarks, synthetic data pipelines, validation workflows, or model evaluation infrastructure
  • Comfort working across messy human and technical systems, including domain experts, vendors, generated data, model outputs, graders, and infrastructure
  • Strong written communication and the ability to explain methodology clearly to researchers, engineers, labs, and external audiences

Nice-to-Haves

  • Experience leading teams on ambiguous technical projects from problem definition through implementation and iteration
  • Experience working with subject-matter experts to capture domain judgment and convert it into scalable review or generation systems
  • Be comfortable designing metrics, experiments, and QA/QC processes, not just executing them
  • Early-stage startup experience with ability to work independently in fast-paced environments
  • Be detail-oriented and able to spot subtle inconsistencies or edge cases in data
