Senior Software Engineer in Test

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 isproject-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

What we look for

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)
