SDET API with Python – Warsaw (Hybrid)

SDET API with Python – Warsaw (Hybrid)

Join our Test Engineering team and drive quality for complex backend systems.

We’re looking for a mid Test Automation Engineer who takes ownership, thinks beyond the test case, and thrives in a fast-paced, automation-first environment. You'll work on a backend-heavy product area, ensuring reliability, coverage, and speed — from API level to CI/CD.

📌 Role Overview

🛠️ Must-Have Technical Skills

• Strong Python – clean, maintainable test code & utilities

• API/backend testing with Pytest (fixtures, parametrization, assertions, test organization)

• CI/CD experience (Jenkins or similar) – pipeline integration, flaky test troubleshooting, reporting

• End-to-end debugging – logs, root cause analysis, reproduction

• Linux basics (shell, environment, debugging) + SQL basics for data validation

🌟 Nice-to-Have (Desired Skills)

• UI test automation with Playwright (page objects, stable selectors, async handling)

• Experience testing REST / microservices across varied stacks

• Practical use of GenAI tools (Copilot-like assistants) to accelerate test development while maintaining quality

📋 What You’ll Do (Responsibilities)

• Own quality for a backend-heavy product area – aim for ~80% automation / 10–20% manual where needed

• Design robust automated coverage for business flows, including integration with partner systems

• Integrate tests into CI/CD pipelines, reduce flakiness, and improve feedback speed

• Debug failures end-to-end, validate assumptions, and drive root cause analysis

• Work proactively – spot gaps in coverage, stability, or process and improve them without being asked

• Communicate clearly – write concise updates, defect reports, and explain risks to engineers and stakeholders

• Collaborate with Dev, DevOps, and Product in agile teams – participate in design discussions and quality strategy

✅ What We’re Looking For (Mindset & Fit)

• Quality-first mindset – challenges assumptions, prioritizes customer impact and reliability

• Balances speed with robustness – knows when to automate and when manual testing adds value

• Follows through – takes ownership from discovery to resolution
