We are seeking an iGaming Quality Engineer to join our team on a contractual basis. The role is fully remote, with occasional travel required to our headquarters in Málaga, Spain. Candidates must operate through a fully registered limited company.

THE ROLE

We build slot games played by millions — and we need someone who can break them before our players do.

As a iGaming Quality Engineer, you'll be embedded directly in game development squads, owning quality across the full lifecycle of Game Development: from early playability reviews and math verification to cross-browser regression suites and live certification sign-off.

You'll work at the intersection of game design, frontend engineering, and regulatory compliance — ensuring every spin, every win animation, every bonus trigger is pixel-perfect, mathematically sound with the correct payment accuracy, and jurisdiction-ready.

WHAT YOU'LL DO

- Design and execute test strategies for slot games and other casino product lines, covering core mechanic loops, free spins, cascades, bonus buys, and progressive jackpots.

- Verify frontend RNG output against certified math models, validating pay tables, RTP values, hit frequencies, and volatility bands.

- Build and maintain automated regression suites using Playwright or Cypress targeting critical game-state flows, ensuring rapid feedback on every build.

- Conduct cross-device and cross-browser testing (Chrome, Safari, Firefox, mobile iOS/Android), documenting rendering defects and frame-rate regressions.

- Collaborate with artists and animators to validate Spine/PixiJS animations, transition states, and audio sync across game events.





- Support regulatory certification testing for MGA and other jurisdictions — preparing evidence packs and liaising with labs.

- Integrate quality gates into CI/CD pipelines; define pass/fail criteria for automated smoke, sanity, and performance checks on every merge.

- Participate in design reviews and sprint planning, raising testability concerns early and contributing to definition-of-done standards across squads.

REQUIRED SKILLS

- Industry Experience : Previous experience in iGaming is required for this role

- Core QE : Test planning · Bug lifecycle · Regression suites · Root cause analysis · Risk-based testing

- Frontend: JavaScript / TypeScript · PixiJS · Chrome DevTools · Browser profiling

- Automation: Playwright · Selenium · Cypress · CI/CD (GitHub Actions) · API mocking

- iGaming Domain: Slot math basics · RTP / RNG concepts · Bonus mechanics

- Practices: BDD, TDD, API testing

NICE TO HAVE

- Scripting bonus simulations or RTP verification tools in Python or Node.js.

- Knowledge of responsible gambling UX requirements and in-game safeguard features.

- Previous work in a regulated gambling, fintech, or payments QE environment

WHO YOU ARE

- A player at heart — you think about quality from the player's perspective first, not just the ticket tracker.

- Methodical and detail-obsessed: a misaligned win frame or a one-frame audio stutter bothers you the same way a logic bug does.

- Collaborative by nature — you thrive working closely with developers, artists, producers, and compliance teams without silos.

- Comfortable with ambiguity in early-stage game development, able to adapt test plans as designs evolve mid-sprint.

- A clear communicator who writes sharp bug reports and gives focused, constructive feedback in design reviews.
