QA Engineer

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.

We’re a small, highly focused team. If you want to work deeply on hard problems, see your work ship to production quickly, and influence how AI safety is actually built – you’re the one we need.

Responsibilities:

• 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

Requiremenents

• 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
