Senior QA Engineer (Manual E2E)

About the Role

The company is seeking a senior QA engineer to take ownership of end-to-end quality across its entire technology stack, which includes web, native mobile applications, Unity-based games, and the supporting backend. This role requires a deep understanding of system behavior, ensuring not only basic functionality but also the correctness of mathematical calculations, money flows, promotions, and game logic under real-world conditions across all client platforms.

Responsibilities

• Own end-to-end manual testing across web client, iOS app, Android app, and backend services, including Unity games within each client.
• Verify cross-platform consistency, ensuring identical behavior for the same game, account, and session across different browsers and mobile devices.
• Verify game logic, RNG behavior, payout flows, and transactional integrity in a sweepstakes context where correctness is critical.
• Test promotions and bonus mechanics end-to-end, covering eligibility rules, trigger conditions, reward delivery, expiration, and interaction with other active promotions.
• Validate player segmentation logic to ensure correct offer and campaign delivery and prevent segment edge cases.
• Test admin panel features, including back-office tools for configuring promotions, managing players, adjusting balances, and operating the live product.
• Manage app version testing, including regression across supported iOS/Android versions, forced-update flows, backward compatibility, and staged rollouts.
• Test server APIs, message flows, and edge cases independently of any client.
• Reproduce, isolate, and document bugs with sufficient detail for engineers to fix them efficiently, identifying whether issues are client-specific, admin-side, or server-side.
• Design and maintain test plans for new features, regression suites, and release candidates across all clients.
• Partner directly with developers, product, game designers, and the promotions/CRM team throughout the development cycle.
• Help shape the QA process as the team and product scale.

Requirements

• 5+ years in QA, with at least 2 years in a senior or lead capacity.
• Strong hands-on experience testing web applications, mobile apps (iOS and Android), and backend systems (REST APIs, async flows, databases).
• Experience testing Unity games or other real-time interactive clients (strongly preferred).
• Experience testing complex business logic, such as promotions, segmentation, eligibility rules, or similar configurable systems with a large matrix of possible states.
• Experience testing admin/back-office tools and understanding their impact on the player experience.
• Sharp analytical instincts to identify gaps in specifications and design effective tests.
• Comfort with browser dev tools, Charles/Proxyman, Postman, Xcode/Android Studio, SQL clients, and log analysis.
• Cross-browser and cross-device testing experience.
• Clear written communication in English; Hebrew a plus.
• Nice to have: Background in iGaming, social casino, sweepstakes, or real-money gaming.
• Nice to have: Familiarity with payment flows, KYC/compliance testing, or fraud edge cases.
• Nice to have: Experience with CRM, marketing automation, or player engagement platforms.
• Nice to have: Exposure to test automation frameworks (Playwright, Appium, etc.).
