Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project‑based as an independent freelance contributor and does not create an employment relationship with Toloka or our clients

What this opportunity involves

As an independent freelance contributor, you choose which projects to join and how you organize your work, as long as deliverables meet the project requirements and deadlines.

While each project involves unique tasks, contributors may:

• Create structured test cases that simulate complex human workflows
• Define gold-standard behavior and scoring logic to evaluate agent actions
• Analyze agent logs, failure modes, and decision paths
• Work with code repositories and test frameworks to validate your scenarios
• Iterate on prompts, instructions, and test cases to improve clarity and difficulty
• Ensure that scenarios are production-ready, easy to run, and reusable

What we look for

This opportunity is a good fit for software engineers, open to part-time, non-permanent projects. Ideally, contributors will have:

• 3+ of software development experience with strong Python focus
• Experience with Git and code repositories
• Comfortable with structured formats like JSON/YAML for scenario description
• Understanding core LLM limitations (hallucinations, bias, context limits) and how these affect evaluation design
• Familiarity with Docker
• English proficiency – B2
