In this role, you will work closely with developers, product owners, and other QA engineers to validate the functionality and stability of our backend services and integrations. Your work will be essential in ensuring that our systems behave correctly across services, APIs, and data flows.

• Collaborate closely with developers to investigate issues and verify fixes
• Perform regression testing to ensure system stability across releases
• Contribute to test automation where applicable, particularly for API and backend testing
• Suggest improvements to testing processes, tools, and quality practices

We're seeking someone equally skilled at spotting existing bugs and at predicting potential issues, either during the release cycle or throughout the product lifecycle.

• Analytical thinking with strong problem-spotting skills
• Advocacy for quality in every stage of the process
• Keen eye for detail and commitment to excellence
• Passion for process improvement and raising testing standards
• User-focused, with a proactive problem-solving mindset
• Strong communicator and collaborative team player
• Fluency in English and Greek (both written and verbal)

• 2+ years of prior QA/testing experience
• Knowledge of structured testing methods and procedures
• Familiarity with agile development methodologies and Test-Driven Development (TDD)

• Experience in testing both web and mobile applications
• Experience with version control systems (git) and issue tracking tools (e.g., ClickUp)

• Postman scripting experience
• ISTQB certification
• Familiarity with e-commerce platforms and challenges

The health of our company and the success of our products is directly related to the health of our team and the work environment we create for ourselves. With this in mind, we strive to provide an inclusive and positive working environment. In this respect, we offer:

• Competitive compensation package
