Job Description

Please submit your CV in English and indicate your level of English proficiency.

Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems.

What This Opportunity Involves

You’ll create challenging coding test cases that push AI coding systems to their limits:

  • Review and refine realistic coding tasks based on provided production codebases with realistic scope, requirements and information sources
  • Write comprehensive functional tests that validate actual end-to-end behavior and edge‑cases, not just superficial checks
  • Craft fair but hard challenges where the AI has all the context it needs, but has to work for it (information scattered across files and external sources, complex reasoning required)
  • Analyze AI failures to understand what the model struggles with vs. what it masters
  • Iterate based on feedback...
