Job Title: Data ScientistJob Type: ContractorLocation: Remote

  • Role Overview

Partnering with a leading AI research organization to engage experienced data scientists for a project focused on evaluating how well AI systems perform real-world data science work. Rather than producing deliverables yourself, you will define what excellent work looks like: designing task-specific grading criteria and scoring completed work samples with rigorous, well-reasoned written justifications.

  • Key Responsibilities
  • Design precise, task-specific grading criteria for real-world data science deliverables (analyses, models, dashboards, experiment readouts, and written recommendations)
  • Score AI-generated and human work samples against those criteria, with detailed written justifications for every score
  • Apply consistent, evidence-based judgment so that scores are reproducible and defensible
  • Incorporate structured feedback from senior reviewers and iterate quickly on your work
  • Ideal Qualifications
  • 5+ years of professional data science experience in industry
  • Background in business operations, product, or growth data science at top-tier technology companies
  • Deep fluency in experiment design and A/B testing, metric definition, SQL/Python analysis, and communicating findings to executive stakeholders
  • Exceptionally strong written communication
  • Detail-oriented, consistent, and comfortable having your judgment reviewed and calibrated against peers
  • Prior experience with AI training, evaluation, or human-data projects is a strong plus
  • Application Process
  • Submit your resume or relevant technical background to get started
  • Qualified applicants may be asked to complete a brief technical assessment or submit additional information

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request. Contract and Payment Terms

  • You will be engaged as an independent contractor.
  • This is a fully remote role that can be completed on your own schedule.
  • Projects can be extended, shortened, or concluded early depending on needs and performance.
  • Payments are weekly on Stripe or Wise based on services rendered.
