Description du poste

TLDR

We’re looking for a QA Engineer to help us build reliable, scalable testing infrastructure. You’ll work with Playwright, Python, and CI/CD pipelines to own end-to-end quality across our platform, improve test reliability and speed, and help shape engineering quality standards.

About Us

White Circle is an AI Safety company building the safety, reliability, and optimization layer for AI systems. At the core of our platform are policies – simple natural-language rules that define what an AI model should and shouldn’t do. We automatically test, enforce, and continuously improve these policies at scale.

• We’ve raised $11M from top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others
• We process over one hundred million API calls every month
• We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model

You will:

• Design, build, and maintain end-to-end test automation frameworks for our web platform and APIs
• Own test coverage for new features
• Integrate automated test suites into CI/CD pipelines
• Write clear, reproducible bug reports and work closely with engineers to get them resolved
• Build exploratory and regression test plans for each release cycle
• Improve test reliability & speed
• Help the team develop a quality mindset: review testability in design, flag risks early

You’ll fit right in if you:

• Have 2+ years of QA automation experience & you’ve built frameworks from scratch
• Have experience with Playwright for end-to-end UI testing and know how to structure scalable test suites
• Write clean automation code in Python (pytest, fixtures, parametrize)
• Have plugged automated tests into CI/CD pipelines (GitHub Actions, GitLab CI, or similar)
• Communicate clearly and work well with others & have fluent English
• Have experience working with AI coding agents and LLM-powered developer tools, and understand how to use them effectively to improve productivity and testing workflows
• Are curious, proactive, and eager to learn new things: you ask questions, think critically, and constantly look for ways to improve and optimise existing processes and solutions

A big plus:

• Experience testing AI or LLM-based products, handling non-deterministic outputs, confidence scoring, edge-case prompts
• Familiarity with performance or load testing (k6, Locust)
• Experience with Postman, Insomnia, Yaak or API contract testing
• Background in security-aware QA or SOC 2 environments

Why White Circle

• Paid time off in line with your local regulations, no matter where you work from
• Work from Paris (hybrid) + relocation package
• Best medical insurance in France
• All the hardware, tools, and services you need
• Covered subscriptions for AI agents and IDEs
• Team off-sites twice a year: we’ve recently been to the Alps and to Saint-Tropez
