Description

  • Own end-to-end quality design for managed service studies, including rubrics, acceptance criteria, defect taxonomies, severity models, and definitions of done.
  • Define, implement, and maintain quality measurement systems such as sampling plans, golden sets, calibration protocols, agreement targets, adjudication workflows, and drift detection.
  • Build and deploy automated quality checks and launch gates using Python and SQL, including validation, anomaly detection, consistency testing, and label distribution monitoring.
  • Design and run launch readiness processes, including pre-launch checks, pilot calibration, ramp criteria, full-launch thresholds, and pause or rollback mechanisms.
  • Partner with Product and Engineering to embed quality controls and authenticity checks into workflows, tooling, and escalation paths.
  • Write and continuously improve guidelines and training materials for participants, reviewers, and internal teams.
  • Investigate quality and integrity issues end to end and drive corrective and preventive actions.
  • Build dashboards and operating cadences to track defect rates, rework, throughput versus quality trade-offs, integrity events, and SLA adherence.
  • Lead calibration sessions and coach QA leads and reviewers to improve consistency and rubric application.
  • Translate one-off fixes into repeatable, scalable playbooks across customers, programs, and study types.

Requirements

  • 5+ years of experience in quality engineering, data or annotation quality, analytics engineering, trust and integrity, or ML/LLM evaluation operations.
  • Strong proficiency in Python and SQL.
  • Comfort applying statistical concepts such as sampling strategies, confidence levels, and agreement metrics.
  • Proven ability to turn ambiguous or messy quality problems into clear metrics, automated checks, and durable process improvements.
  • Strong quality systems thinking with the ability to translate complex edge cases into clear rules, tests, rubrics, and governance mechanisms.
  • Hands-on experience instrumenting workflows and implementing pragmatic automation that catches quality and integrity issues early.
  • Demonstrated ability to influence cross-functional teams and drive change without direct authority.
  • Strong customer empathy and understanding of what trustworthy data means for research, AI training, and evaluation use cases.
  • Familiarity with data collection mechanics such as screeners, quota/routing constraints, and study design patterns is preferred.
  • LLM evals, red teaming, or policy-based annotation experience is preferred.
  • Data/versioning discipline, including dataset lineage, change control, and reproducibility, is preferred.
  • Experience with integrity or fraud detection systems and anti-abuse tooling is preferred.

Benefits

  • Competitive salary with base pay, equity, and benefits for eligible roles.
  • Opportunity to earn a cash variable element such as a bonus or commission in many roles.
  • Remote working.
  • Mission-driven culture.
  • Salary range disclosed for the role based on location and candidate experience.
