Senior Software Engineer in Test (Full-Stack/Python)

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

• 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
