The position involves building and maintaining Playwright (TypeScript) test suites, integrating tests into CI/CD, and improving QA processes in an Agile environment. The engineer also leverages AI tools to enhance testing efficiency and quality. 🗂️ Requirements: 3+ years commercial QA experience, Strong automation or frontend development background, Practical experience with Playwright, Experience building test suites from scratch, Ability to define appropriate testing approach (e2e, manual), Hands-on experience with AI tools (agents, MCP, prompt engineering), Experience with REST API testing, Experience configuring CI/CD pipelines, Experience working in Agile environment 📃 Skills: TypeScript, Playwright, REST, CI/CD, AI, MCP, Automation, Agile 🏢 Description: Who we're looking for We're looking for a QA Engineer who thinks about quality holistically - not someone who writes tests because they were told to, but someone who can look at a feature and decide what actually needs testing, and how. You know when to reach for e2e tests, when unit tests are the right answer, and when a thorough manual pass is enough. You think in terms of risk - what happens if this breaks, and who feels it - rather than chasing coverage for its own sake. You care about quality before and after release. In an era where AI can write boilerplate in seconds, what sets you apart is judgment: knowing what matters, what's fragile, where the real risk lies - and whether a test actually verifies something or just looks like it does. Playwright is a tool you're comfortable with, not the definition of your role. Your responsibilities Assess features and define the right testing approach - e2e, manual, or a combination Apply risk-based thinking to prioritise testing where the impact is highest Write and maintain automated e2e tests in Playwright (TypeScript) where they add the most value Participate in feature refinement - catch ambiguities early, flag risks, challenge assumptions, provide estimates Identify gaps in test coverage and take initiative to close them Report defects clearly and work with developers through the fix-and-verify loop Configure and maintain automated tests in CI/CD pipelines Help keep an eye on quality in production - monitoring, logs, and the feedback loop on what slipped through Improve QA processes in an Agile environment - propose changes, drive them through Use AI tools to work faster and smarter - agents, prompt engineering, workflow automation - while critically reviewing what they produce Share knowledge, review tests, and help raise the quality bar across the team Requirements 3+ years of commercial QA experience, with a strong automation or frontend development background Ability to evaluate testing needs independently and choose the right approach Solid practical knowledge of Playwright Experience building a test suite from scratch, not only maintaining existing ones Hands-on experience with AI tools: agents, mcp servers, prompt engineering A critical eye for test quality - able to tell a meaningful test from a hollow one REST API testing experience Familiarity with CI/CD configuration Experience working in an Agile team, with solid bug reporting and refinement habits Good Polish and English (B2 minimum) What sets a strong candidate apart Awareness of non-functional quality: accessibility, basic performance, security fundamentals (knowing when to raise them, not necessarily owning them) Disciplined about test data and environments - deterministic, reproducible, isolated from things you can't control Sets testing standards for the team and evangelizes a quality-first mindset Experience in building test observability Can set up and integrate test reporting and analytics tools, turning raw results into trends and insights the team actually acts on Tech stack TypeScript · Playwright · REST API · CI/CD What we offer 14 000-18 000 PLN + VAT (B2B) Flexible working hours Fully remote, but you are always welcome at our office in Old Mokotów, Warsaw Co-founding of Multisport card and Enel-med medical care Recruitment process Intro call with HR - ~30 min Technical screen with Marcin (QA Lead) - experience + technical questions, ~15 min Technical interview with short live coding session with Marcin ~2 hours Offer meeting We provide feedback to every candidate, regardless of the outcome.
