Manual QA Engineer - Web Products

About the role

CoreStar is looking for a QA Engineer to take ownership of quality across its web products, both live sites and those being prepared for launch. This is a hands-on, individual contributor role: you identify where a product is fragile and back up your claims with evidence.

Key responsibilities

• Treat product quality as your own, raising risks early and explaining why some tests are deep and others light
• Choose the right test technique, such as exploratory testing, instead of a full regression pass when possible
• Write precise reports so remote colleagues can act on them without follow-up calls
• Work diplomatically with dev, design and business teams to keep focus on the release date
• Test across the release lifecycle: hardening new sites for launch and verifying changes safely on live products (smoke tests, post-release checks, regression for hotfixes)

Required profile

• 3+ years in manual QA of web products, including sites running in production with real users
• Solid knowledge of QA fundamentals: testing processes, methodologies, test documentation and client-server architecture
• Functional and non-functional testing: cross-browser and cross-device compatibility, responsive layout, perceived performance, basic accessibility, usability and security hygiene (input handling, authorization, exposed data)
• L10n and i18n testing
• English at B1 level or above

Required skills

• API and browser-level testing: REST API testing with Postman / Swagger, DevTools (network, console, storage, device emulation)
• Monitoring and logging systems such as Grafana or Coralogix, using logs and dashboards to investigate issues

What we offer

• 24 working days of paid annual leave and 6 days of paid sick leave
• Official employment and medical insurance
• Coffee zone with fruit and snacks, corporate lunch, gym and sports classes
• Healthy, friendly work atmosphere and partially covered Greek and English language classes
