[Hiring] Senior QA Engineer @Bitcoin Suisse AG

Role Description

We're looking for a hands-on Senior QA Engineer to strengthen quality across a portfolio of applications and the workflows that connect them. You'll be part of a cross-location test team and work with engineers, product owners, and other stakeholders across teams, learning the systems and business domains well enough to focus testing where it reduces the most risk. Our landscape includes message-driven, distributed systems, so effective testing must account for behavior across services and asynchronous workflows.

You'll shape how features are tested from refinement through release:

• Clarifying expected behavior, identifying risks and testability gaps early.
• Exploring the product and building maintainable automated coverage.

This is an independent role with broad influence, not a role limited to executing test cases or producing automation for its own sake.

Our existing test estate is primarily C#/.NET, Gherkin-based BDD with Reqnroll, and Azure DevOps pipelines. It includes both API and browser-based tests, with Selenium in established suites and Playwright in selected projects. You don't need to know every tool on day one, but you should be comfortable improving an established automation landscape and choosing the right level of testing for the risk.

Qualifications

• Significant hands-on QA experience testing complex applications and integrations.
• Strong testing judgment: ability to select techniques based on risk and explain untested areas.
• Practical experience designing and maintaining automated tests in a modern development and CI environment.
• Experience with C#/.NET and at least one browser automation framework, such as Selenium or Playwright.
• Experience testing APIs and service integrations, including using tools such as Swagger or Postman.
• Familiarity with BDD and Gherkin; Reqnroll or SpecFlow experience is an advantage.
• Experience working with CI pipelines and test reporting; Azure DevOps experience is an advantage.
• Strong communication skills to collaborate across teams and raise quality risks early.
• Curiosity and independence: ability to learn unfamiliar systems and prioritize work without a prescriptive daily task list.

Requirements

• Partner with product and engineering teams during refinement to clarify acceptance criteria, edge cases, dependencies, and testability.
• Create a risk-based test approach for features and end-to-end workflows spanning multiple applications and services.
• Perform exploratory and structured manual testing where human investigation is the best way to find important defects.
• Build and maintain reliable automated tests at the appropriate levels, focusing on API and integration coverage as well as critical UI journeys.
• Extend and improve our C#/.NET test suites and BDD scenarios; use browser automation such as Selenium or Playwright where it provides meaningful coverage.
• Integrate tests into Azure DevOps pipelines for fast, actionable feedback and diagnose flaky or slow tests.
• Use API contracts and tools such as Swagger and Postman to investigate behavior, validate integrations, and support test setup.
• Investigate defects with engineers, contribute to root-cause analysis, and use findings to improve test coverage and prevent recurrence.
• Improve test data, environment use, diagnostics, and reporting for reproducible and useful failures.
• Take responsibility for quality across application releases: coordinate release testing, ensure critical risks and defects are visible, and provide a clear readiness recommendation based on evidence and agreed criteria.
• Use Azure DevOps test plans or suites where they help coordinate coverage and provide traceability.

Benefits

• Work with crypto native experts.
• Positive and supportive team culture that relies on common goals, ambitions, and values.
• Regular team events and activities.
• High level of autonomy and responsibility.
• Multisport Card.
• Office location in the new Bratislava downtown (Jurkovičova tepláreň).
• Flexibility of working across designated EU countries, with up to 20 days a year to combine work and travel.
