DUTIES AND RESPONSIBILITIES:
- Test client typed HFSM spin-lifecycle transitions, state consistency, and session recovery/reconnection across mid-spin, free spins, and bonus rounds.
- Verify PixiJS v8 rendering, Spine-Pixi v8 skeletal animations, and GSAP spin-stop choreography on target mobile and desktop browsers.
- Validate jurisdiction-specific rules, mandatory messaging, and audit-trail behavior driven by configuration profiles.
- Test offline mocked backend implementations and verify network resilience under packet loss or mid-spin disconnections.
- Perform engine lifecycle QA for spin generation, keep-generate, and history-replay endpoints to confirm deterministic replay.
- Validate RGS adapters for SDK-injected RNG sourcing, wallet transaction accuracy, and math/RTP compliance against certified models.
- Audit backend storage and messaging (PostgreSQL, Redis, RabbitMQ) and design load tests using K6 or JMeter for spin-endpoint latency/throughput.
- Produce precise technical bug reports identifying root causes across HFSM states, engine determinism, database locks, or queue sync issues.
Requirements:
- 3+ years of technical QA experience covering client-rendered game engines and high-concurrency backend services.
- Basic understanding of TypeScript, PixiJS v8, Spine-Pixi v8, GSAP, and client architecture layers (Presentation / HFSM / Domain / Network / Platform).
- Basic understanding of Go services, RGS/SDK integration contracts, NestJS, and backend support via Redis and RabbitMQ.
- Literacy in slot mechanics (paylines/clusters/Megaways, RTP, volatility, free spins, bonus buy, ante bet, max-win).
- Experience or theoretical knowledge of performance testing tools (e.g., K6, JMeter) for backend load and client frame-budget profiling.
- Proven ability to utilize LLMs and AI coding assistants for test case generation, documentation analysis, and code auditing.
- Strong understanding of concurrency issues and race conditions.
- Excellent technical communication skills to explain failures across complex frontend and backend layers.
