Principal/Senior Test & QA Developer (Automation & Game Validation) Location: Remote / Varna HQ Type: Full-Time Level: Senior / Principal Start Date: ASAP ________________________________________ About Us We’re a technology-first game studio with bold ambition: build the world’s most performant, delightful, and technically advanced slot games. Each Game Crew owns its product fully — but we rely on shared experts like you to make every build rock-solid. As a Principal/Senior Test & QA Developer, you’ll build test automation, validation tools, and observability systems that ensure every game meets our bar: pixel-perfect visuals, zero-bug gameplay, and fair-play math. You’re not just catching bugs — you're crafting confidence. ________________________________________ What You'll Do

• Design and implement test automation frameworks for slot and casino games across web and mobile.
• Build simulation pipelines to verify game math (RTP, volatility, win frequency) over millions of spins.
• Develop E2E, integration, and performance test suites in CI pipelines.
• Work closely with engineers, artists, and game mathematicians to verify rendering, animation, audio sync, and logic.
• Investigate issues with real user telemetry and production logs.
• Contribute to internal tools for test orchestration, replay, and game validation dashboards.

________________________________________ Tools & Stack

• JavaScript/TypeScript, Playwright, Jest, Vitest, Puppeteer, Cucumber
• Python for data modeling and math simulation
• WebGL canvas/image diffing
• GitHub Actions, Docker, AWS for test environments
• Sentry, CloudWatch, Kibana

________________________________________ What We’re Looking For

• 10+ years of experience in test automation or quality engineering — especially in games, media, or UI-heavy applications.
• Deep experience with modern JavaScript-based test frameworks.
• Comfort with probabilistic testing, simulations, and math result validation.
• Obsession with quality, stability, and player trust.
• Ability to define a long-term QA vision and build tools, not just write tests.

________________________________________ Why Join Us?

• Own testing across world-class games used by millions.
• Build the future of game validation, automation, and observability.
• Work alongside the best — from cloud engineers to game artists.
• Excellent compensation, stock options, and performance bonus.
