Senior QA Engineer (Python)

On behalf of our client, a global, technology-driven enterprise, we are currently looking for an experienced Senior QA Engineer. In this role, you will work closely with developers, product managers, and end-users to ensure the highest standards of software quality across the entire development lifecycle.

The company builds highly complex, data-intensive applications where QA is treated as a core engineering discipline, rather than an afterthought.

What you will be doing:

• Designing and executing comprehensive testing strategies, including functional, integration, regression, UI, and data validation testing.

• Actively identifying software defects and providing actionable feedback on product usability.

• Creating and maintaining test automation scripts, as well as participating in peer code reviews.

• Collaborating directly with business stakeholders to gather, understand, and refine requirements.

• Taking part in agile ceremonies and technical brainstorming sessions.

• Identifying potential technical risks early in the development pipeline.

• Mentoring the team on QA best practices and optimizing internal developer testing frameworks.

• Assisting with the creation of internal documentation and helping train end-users on new application features.

What is expected of you:

• At least 8 years of commercial experience in a Software QA / Testing role.

• Solid coding skills in Python. You should be comfortable reading code, writing scripts, and getting your hands dirty to effectively "break" applications.

• Actively using AI tools (such as GitHub Copilot, Claude, Codex, etc.) on a daily basis to accelerate your coding, write better tests, and quickly learn new platforms.

• Practical knowledge of test automation frameworks and integrating tests into CI/CD pipelines.

• Proficiency with version control systems (e.g., Git).

• Strong analytical mindset, great time management, and a highly adaptable, problem-solving attitude.

• Eagerness to learn new platforms and technologies quickly.

What our client offers:

• Hybrid work model in Warsaw (minimum 3 days a week in the office - strictly non-negotiable).

• Contract of Employment (UoP) with increased tax-deductible costs (KUP).

• Annual performance bonus.

• Private medical care (including full dental care).

• Lunch card to cover your daily meals.

• Multisport card.
