Senior QA Engineer

Opis oferty

Join Kruko as a Senior QA Engineer and take ownership of quality assurance in a fast-paced software development environment.

We build web and mobile applications for international clients, with AI playing an important role in our development process.

Our developers use Claude and AI-powered workflows extensively, allowing them to deliver changes at a high pace. We're looking for a QA Engineer who can keep up with this environment, not by testing more manually, but by working smarter.

You should be comfortable combining strong testing fundamentals, technical skills, automation and AI-assisted workflows to make quality assurance efficient, scalable and reliable.

Wymagania

• Several years of commercial QA experience, with the ability to independently own testing at a senior level.
• Excellent understanding of software testing principles, exploratory testing, risk-based testing and test design.
• Strong analytical skills and the ability to identify problems that are not explicitly described in requirements.
• Experience testing REST APIs using Postman or similar tools.
• Practical experience with test automation, preferably Playwright.
• Confidence investigating technical issues using logs, monitoring tools and available diagnostic information.
• Ability to use AI tools effectively in everyday work, going beyond simple prompts to build repeatable, efficient testing workflows.
• A proactive mindset: you identify risks, challenge unclear requirements and propose improvements rather than waiting for assigned test cases.
• Strong independence, ownership and the ability to prioritize work in a rapidly changing environment.
• Clear communication skills and English at C1 level.
