QA Automation Engineer

About LeanCode

At LeanCode, we build core technology solutions for global, large-scale organizations. We are a global leader in Flutter, an official Flutter Consultancy, and one of only four agencies at the Flutter Advisory Board - working closely with Google and delivering projects worldwide: from the US and LatAm, through Europe (UK, DACH, Nordics), to Australia.

Our future-proof strategy is built around two core pillars. The first is Flutter for Enterprise & Scaleups - delivering and migrating large-scale, business-critical systems to Flutter, serving hundreds of thousands to millions of users. The second is AI Transformation - helping software teams adopt AI-assisted development to significantly increase productivity and delivery predictability.

At our core, we are a team of 75+ engineers, designers, and specialists, who learn fast, constantly improve, and never cheat - both in how we build software and how we work with our clients.

We are looking for ambitious professionals who can join our team in the QA Automation Engineer role. You’ll be responsible for writing and maintaining automated tests and preparing infrastructure to run them. You’ll also take part in the development of our AI tooling - we’re working with cutting-edge AI coding assistants and agents, which we leverage to speed up the development process and learning. We use AI tools daily - for test generation, code analysis, and debugging. Also, we're always looking for better ways to integrate them into our testing workflows.

At LeanCode, we’re also developing Patrol - the most popular E2E testing framework for Flutter. As a team member, you’ll be involved in the process of shaping the framework, providing constant feedback and suggesting new features. We spend a lot of time discussing best practices and possible ways to make UI tests more efficient, readable, and maintainable.

Your path in the company can evolve in many ways - from mastering test automation across mobile and web, through becoming a Patrol expert who shapes the framework itself, to stepping into a consulting role where you advise clients on test automation strategy. We back ambitious people with mentorship and real opportunities to step up.

Responsibilities:

• Writing and maintaining automated tests in projects for our clients in Patrol and Playwright;

• Owning test automation strategy for client projects - from choosing the right approach to ensuring reliable, fast test suites;

• Setting up and optimizing testing pipelines using CI/CD solutions and device farms - solving real challenges like flaky tests, slow feedback loops, and cross-platform coverage;

• Developing AI tooling around automated testing;

• Developing Patrol framework and providing support for our users;

• Providing expertise about Patrol for our clients.

Requirements:

• Fluency in coding in any modern programming language;

• Experience in any test automation framework;

• Interest in or experience with AI-assisted development tools (e.g. using LLMs for test generation, code analysis, or debugging);

• Nice to have - Familiarity with CI/CD concepts and how testing fits into delivery pipelines;

• Nice to have - Basic understanding of mobile or web app architecture (how frontend talks to backend, APIs, etc.);

• Eagerness to learn new things;

• Good command of English (B2, written and spoken);

• Fluent Polish (C2, written and spoken)

• Great analytical skills and attention to detail.

Other important facts on what you can expect:

• Work at our HQ (Warsaw, Służew metro station) or remotely;

• Comfortable, spacious office with a large backyard (where we have frequent BBQ parties);

• Specialty coffee from a local roastery (yes, we are coffee freaks…);

• Frequent technical talks from various areas of software development (system architecture, soft skills, mobile & frontend trends, UX);

• Knowledge sharing during weekly QA team meetings - you’ll have a chance to learn from others and discuss current topics;

• We play table tennis and table soccer (quite a lot), football matches on real pitch are also popular :).
