iGaming Quality Engineer (Contract)

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.
