Freelance Agent Evaluation Engineer

Job description / Role

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. Participation is project-based, not permanent employment.

What this opportunity involves

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+ years 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
