Mindrift - Freelance AI Evaluation Engineer (Python/Full-Stack)

AI Engineer is needed in Manchester, United Kingdom.

Client: Mindrift

Location: Manchester, United Kingdom

Contract: undefined

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. Participation is project-based, not permanent employment.

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 from expert QA reviewers who score your work on 7 quality criteria.

Requirements

This opportunity is a good fit for experienced developers, software engineers, and/or test automation specialists open to part-time, non-permanent projects. Ideally, contributors will have:

• Degree in Computer Science, Software Engineering or related fields.
• 5+ years in software development, primarily Python (pytest, async/await, subprocess, file operations).
• Background in Full-Stack development, with an equal focus on building React-based interfaces and robust Back-end systems.
• Experience writing tests (functional, integration - not just running them).
• Docker containers (running evaluations locally in containers).
• CI/CD understanding (GitHub Actions as a user: triggers, labels, reading results).
• English proficiency - B2.
