Job Title: Data Scientist

Job Type: Contractor

Location: 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

Idóneo 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 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.
