We at PEOPLE HUNT are hiring an Integration QA Engineer on behalf of a fast-growing iGaming start-up building a high-load, real-time gaming platform.

In this role, you’ll ensure the stability, accuracy, and reliability of wallet flows, game sessions, and operator integrations. You’ll serve as the quality gate across multiple systems - guaranteeing that every release, update, and integration is smooth, compliant, and audit-ready.

Key Responsibilities

• Test operator integrations, wallet flows, callbacks, session handling, bets/settlements, and full game round lifecycles.

• Validate API contracts (REST/WebSocket), including request/response structures, error handling, and idempotency.

• Conduct end-to-end testing across the full chain - game server → platform → wallet/payment → operator systems.

• Create and maintain test cases, integration checklists, regression suites, and release sign-off criteria.

• Reproduce, document, and track issues; collaborate closely with backend, integrations, product, and operator tech teams.

• Verify compliance with RTP/RNG reporting, correct round closures, and complete audit trail logging.

• Support certification and onboarding of new operators, aggregators, and external partners.

What You Bring

• Experience in QA within iGaming, betting, payments, or other transaction-heavy, high-load systems.

• Strong understanding of wallet models (seamless vs transfer), session tokens, and bet/settlement flows.

• Hands-on experience with API testing tools (Postman, Swagger, Charles, Fiddler, etc.).

• Ability to read logs, analyze JSON payloads, and trace event lifecycles across services.

• Familiarity with SQL querying and message queues (Kafka, RabbitMQ, NATS) is a plus.

• Exceptional attention to detail, structured documentation habits, and clear communication.

• Comfortable working collaboratively with engineering teams and external operator tech teams.

What Makes This Role Unique

• 🚀 Learn from top-tier founders: work with leaders experienced in scaling complex, real-time systems.

• 💡 Startup pace with holding-level ambition: fast execution, high ownership, and bold goals.

• 🧩 Autonomy and impact: freedom to define, test, and improve QA processes and standards.

• 🔄 No legacy constraints: challenge defaults, rebuild systems, and optimize continuously.

• 🕓 Flexible full-time setup: core collaboration hours (11:00–16:00 CET) - structure the rest your way.

• 🌍 People-first culture: balanced day-off policy that respects real life.

• 📈 Room to grow: as the platform and integrations expand, so does your scope and influence.

If you’re passionate about quality, precision, and reliability in complex, high-load environments - this is your opportunity to play a crucial role in delivering a seamless gaming experience.
