SQL Query Verification

About this task

This Growth-stage clinical data company for mental health (501–1,000 employees) is looking for a senior AI Evaluator: Data & Analytics for a rating and review programme for AI output in your own field, 4–10 h a week. Runs AI-written queries on sample data and checks results.

The programme needs subject-matter experts who can tell a good answer from a plausible one in their own field. It works in healthcare, so patient data is never part of the task and privacy rules are strict.

The work is fully remote. Any location in Poland works, with a few hours of overlap with the team's day.

What you deliver

• Run 40 AI-written SQL queries on a sample database and mark wrong joins, filters and aggregations.
• A weekly count of items reviewed, confirmed by the programme lead
• Short calibration notes after the first batch, so your ratings match the guidelines
• Flags for answers that are unsafe, off-topic or wrong in your field

What a week looks like

• Daily: one hour at a time that suits you, inside the agreed window
• Wednesday: ten-minute sync if anything is blocked
• Thursday: weekly summary posted to the shared thread

Duration: Weekly batches for 6 weeks, renewed every four weeks. Accepted when the output matches the agreed checklist and the sample check passes; the recruiter confirms by e-mail.
