Overview

Mercor is collaborating with a prominent AI research lab to recruit seasoned data scientists for a project that assesses AI systems' ability to handle real-world data science tasks. Your role isn't to produce work but to define excellence—crafting detailed scoring rubrics and evaluating sample outputs with clear, written rationales. This is a high-impact, remote contract position paying $120–$170 per hour.

What You'll Do5

  • 1Develop precise, task-specific scoring criteria for data science outputs such as analyses, models, dashboards, experiment results, and written recommendations.
  • 2Evaluate both AI-generated and human-produced work samples against those criteria, providing thorough written justifications for each score.
  • 3Maintain consistent, evidence-based judgment to ensure scores are reproducible and defensible across evaluations.
  • 4Act on structured feedback from senior reviewers, iterating and refining your scoring approach quickly.
  • 5Collaborate with a team of evaluators to calibrate scoring standards and ensure alignment.

Requirements5

  • 1At least 5 years of professional data science experience in an industry setting.
  • 2Background in business, product, or growth data science at top-tier technology companies.
  • 3Deep expertise in experiment design, A/B testing, metric definition, and SQL/Python analysis, plus the ability to communicate findings to executive stakeholders.
  • 4Exceptional written communication skills with attention to detail and consistency.
  • 5Comfort with having your judgment reviewed and calibrated against peers; prior involvement in AI training, evaluation, or human-data projects is a strong plus.

Who Should Apply

This role is ideal for a seasoned data scientist who thrives on setting high standards and systematically evaluating work. You should be detail-oriented, articulate in writing, and comfortable with your judgments being scrutinized and aligned with a team. If you have experience in AI evaluation or training datasets, that’s a bonus.

Salary Insight

The position pays $120–$170 per hour on a contract basis, with exact rate depending on experience and calibration.

Application Tip

In your application, highlight a specific instance where you designed a scoring rubric or evaluation framework—whether for A/B test results, model performance, or a data science deliverable. Demonstrating your ability to define and apply rigorous criteria will set you apart.
