You own how the casino looks, feels, and performs from a games perspective.

• Own thumbnails, game metadata, and naming conventions to keep the catalogue clean and consistent
• Manage game ordering logic and ensure new releases land with the visibility they deserve
• Work closely with product and design on lobby UX improvements
• Own search, filters, recommendation logic inputs, and seasonal or campaign-driven lobby themes
• Audit game configurations regularly to ensure exposure settings align with our risk appetite (max win caps, max bet on bonus, contribution percentages)

Aggregator Coordination

You'll be the primary point of contact for our aggregator partners and direct studio relationships.

• Build strong working relationships with aggregator account managers and direct studio contacts
• Manage the release calendar end-to-end, including activations, scheduling, and go-live readiness
• Configure correct RTP variants, bet ranges, and max win settings per jurisdiction
• Handle escalations on game performance, downtime, or technical issues with calm, clear stakeholder communication
• Coordinate with finance and compliance on reconciliation matters

Promotions Coordination
You'll negotiate and coordinate promotional deals across the studio and aggregator network.

• Negotiate network tournaments, prize drops, exclusive releases, and free spin campaigns
• Secure co-funded promotional activity and favorable commercial terms
• Align promotional calendars with the CRM and marketing roadmap
• Ensure every campaign is configured correctly on both operator and studio sides before going live

We are helping our partner — a fast-growing product company in the iGaming space — find a Senior Java Developer to join their backend team.

This is not a “just write code” role.

This is about building systems, making decisions, and owning the result.

What this role is really about

You’ll be working on a high-load casino product, where:

• systems process real-time events
• performance matters
• architecture decisions have real impact

The team builds services from scratch and owns them end-to-end.

What you’ll be doing

• Build new backend services from scratch
• Participate in architectural and technical decisions
• Work with microservices and distributed systems
• Solve complex technical challenges
• Collaborate in a cross-functional team (product / QA / dev)
• Take ownership of what you build — not just tasks

What we’re looking for

• 5+ years of experience with Java
• Strong experience with microservices architecture (2+ years)
• Deep understanding of distributed systems
• Hands-on experience with:
  • Spring Boot
  • PostgreSQL
  • Kafka (or similar messaging systems)
  • SQL + NoSQL databases
• Experience with AWS / Kubernetes will be a strong plus
• gRPC — nice to have

But more importantly:

You think, not just code

You take ownership

You can explain your decisions

What you get

• Product company (not outsourcing)
• Real impact on architecture and product
• Strong engineering team
• Fast-paced environment with real challenges
• Remote work
