    • We're looking for a QA Engineer to join White Circle, an AI Safety company building the policy enforcement and optimization layer for AI systems. Backed by $11M from senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, and DeepMind, White Circle processes 100M+ API calls monthly and runs its own LLMs in production. This is a manual-first product QA role, with automation as a key tool.

    You will

    • Manually test new features and fixes across the web platform and APIs in fast release cycles, sometimes as short as one working day.

    • Identify the highest-risk areas, run exploratory, smoke, regression, and integration testing, and give clear release feedback.

    • Write concise test plans and checklists, investigate unexpected behavior, and file reproducible bug reports.

    • Work with engineers and product owners to clarify requirements and improve testability before development is complete.

    • Automate stable, business-critical flows with Playwright and Python, and integrate them into CI/CD.

    Requirements

    • 2+ years in QA automation, including building frameworks from scratch.

    • Strong Playwright experience for E2E UI testing and scalable test suite design.

    • Clean Python automation code (pytest, fixtures, parametrize).

    • Hands-on CI/CD integration (GitHub Actions, GitLab CI, or similar).

    • Practical use of AI coding agents and LLM-powered developer tools in testing workflows.

    • Fluent English and clear communication.

    • Based in or relocating to Paris or London (hybrid).

    Bonus

    • Testing AI/LLM products: non-deterministic outputs, confidence scoring, edge-case prompts.

    • Performance or load testing (k6, Locust).

    • API testing tools (Postman, Insomnia, Yaak) or contract testing.

    • Security-aware QA or SOC 2 environments.

    We offer

    • Competitive salary + equity.

    • Hybrid work from Paris or London, relocation package for Paris.

    • Top-tier medical insurance in France and flexible time off.

    • L&D budget, all hardware and tools you need, plus covered AI agent and IDE subscriptions.

    • Team off-sites twice a year.
