Why this role exists:
This role exists to design, build, and maintain backend services across the Casino platform — bonus and promotional mechanics, wallet and transaction flows, game launch and catalog, and game provider integrations — ensuring reliability, correctness, and performance under high load.
What you’ll drive:
Casino platform services
- Design and develop Spring Boot microservices across the casino domain: bonus processing, game launch, lobby and game catalog management.
- Implement and evolve promotional mechanics end-to-end — from bonus crediting and wagering logic to expiry and settlement — with correctness guarantees on real money.
- Integrate third-party game providers, game launch, wallet callbacks (bet/win/refund), provider-side bonus features.
- Build and evolve REST APIs consumed by internal services and external providers, including request signing, authentication, and API versioning.
Reliability & correctness
- Ensure correctness of real-money transaction and bonus flows — idempotency, retries, timeouts, graceful degradation of downstream calls.
- Work with Redis for caching and session state; tune service performance under production load.
- Own observability: metrics (Micrometer/Prometheus, Grafana dashboards), structured logging, alerting.
Quality & delivery
- Write and maintain unit, integration, and functional tests (JUnit 5, Testcontainers).
- Ship via GitLab CI to Kubernetes; participate in code review and incident investigation.
What makes you a GR8 fit:
Must-have
- 5+ years of experience in back end.
- Commercial experience with strong proficiency in Java (17+) and Spring Boot 3.x (Web, Security, Data, Actuator).
- Experience building business-critical domain logic (payments, bonuses, billing, or similar money-adjacent flows).
- Solid experience integrating third-party REST APIs and designing your own.
- Understanding of distributed systems basics: idempotency, consistency, timeouts, retries, caching.
- Experience with SQL and at least one NoSQL store (Redis, Cassandra, or Elasticsearch).
- Upper-intermediate or higher level of English.
Nice-to-have
- Scala experience (parts of our wallet platform run on Scala / Play / Akka).
- Experience with Kafka and event-driven architectures (some of our services use Spring Cloud Stream).
- Experience running services on Kubernetes; familiarity with GitLab CI.
- Familiarity with Prometheus and Grafana.
- iGaming / betting domain experience.
Why you’ll love working here:
Benefits Cafeteria — annual budget you allocate to:
Sports • Medical • Mental health • Home office • Languages.
Work-life & support
- Paid maternity/paternity leave + monthly childcare allowance.
- 20+ vacation days, unlimited sick leave, emergency time off.
- Remote-first + tech support + coworking compensation.

- Learning culture with internal courses + growth programs.
