We are looking for a highly skilled QA Engineer to join our Brand Experience (BX) area. This role takes a holistic approach to Quality Assurance – from functional testing to automation engineering. You will be involved in designing and executing test cases, ranging from manual testing to writing end-to-end and integration testing with our test automation framework. Writing and maintaining automated tests is an important part of this role - but it’s not the whole story. You can have the chance to get involved in evolving our automation frameworks, improving CI/CD processes, and shaping how quality is approached across multiple brands. There’s real room to grow into these areas over time, with increasing ownership and impact as you develop within the team. You will work closely with other Developers, Tech Leads, Architects and Product teams to drive a strong Quality Engineering culture. This is a role for QA engineers who want to understand systems end-to-end, put themselves in the customer’s shoes and drive quality on all fronts. If you enjoy problem-solving, automation, and working in a modern engineering environment — this is the challenge for you. THE WOW  Much like a rollercoaster, life at Betsson Group is fast-paced, full of twists and turns, and always exciting. With more than 2,800 colleagues representing over 75 nationalities across a global network of offices - including 1,500 at our operational headquarters in Malta - every day brings new challenges and opportunities to grow. It may not be for the faint-hearted, but if you thrive on innovation, enjoy pushing boundaries and want to be part of a diverse, international team, then you’ll fit right in at Betsson. A TASTE OF WHAT YOU WILL BE DOING * Create and execute testing scenarios for manual and functional testing on our products using available tools such as physical testing devices and BrowserStack, across multiple platforms * Design, implement, and maintain end-to-end test suites using JavaScript/TypeScript with Playwright. * Create and optimise UI and integration tests that support a multi-brand, multi-jurisdiction ecosystem. * Participate in development lifecycle activities: refinements, technical design discussions, architecture reviews, and quality gate definition. * Implement and maintain test data strategies, mocks, stubs, and service virtualization where appropriate. * Participate in the identification and troubleshooting of issues across frontend, API, and integrations. * Collaborate with engineering teams to improve testability, observability, and debugging capabilities. * Use dashboards and reporting tools (Allure, Grafana, Kibana, OpenSearch, etc.) to analyse failures, detect patterns, and improve reliability. * Drive a quality-first mindset, advocating for automation, engineering excellence, and continuous improvement across BX. * Mentor and support other QA Engineers and Developers in quality best practices, shift-left testing mindset, tooling, and design. WHAT WE ARE LOOKING FOR:   * Strong experience writing and executing test scenarios, covering technical and product requirements, identifying pitfalls and edge cases, to ensure high confidence in our Releases. * Hands-on experience with Playwright, or equivalent automation frameworks (Cypress, Selenium, WebdriverIO) using JavaScript/TypeScript. * Solid understanding of test strategies, including mocking, isolation, reliability improvements, and root-cause analysis. * Proactive ownership mindset, focused on continuous improvement and solving problems at their root. * Excellent communication skills; ability to explain technical concepts and mentor team members. BONUS POINTS FOR: * Experience working with microfrontends, component libraries, or distributed frontend architectures. * Clear understanding of all levels of functional testing, including Unit Testing. * Exposure to non-functional testing, specifically Performance Testing using tools such as K6 or JMeter. * Knowledge of contract testing (Pact or similar) is considered an asset. * Exposure to TDD practices. * Practical experience building and maintaining CI/CD workflows using tools such as GitHub Actions or TeamCity. ABOUT YOU You are someone who thinks like an engineer, not a test executor. You enjoy tackling quality from different perspectives – how the real user perceives our product, thinking at scale and automating scenarios for faster, more robust product iterations. You enjoy understanding systems, and solving complex quality challenges. You bring a strong sense of ownership, curiosity, and attention to detail, and you’re always looking for opportunities to elevate quality through automation and engineering.
