Backend Developer (B2B) - Game Studio

Join the Exciting Journey at tombola!

We are seeking a Software Developer for our backend development team to actively contribute to the design, development and delivery of the game engine services within our B2B platform.

In this team, you’ll be building the systems that allow our games to be used by other businesses. Rather than focusing purely on the player-facing experience, you’ll be working on the technology that connects our games to external partners, ensuring everything runs smoothly, securely and reliably at scale.

The role involves being a part of a newly established team with a focus on learning the business use case around the solution, contributing to the development of new services and showcasing your technical expertise in delivering backend systems that support external integrations.

You will be actively involved in team discussions, decision making and contributing to the development processes.

Find your bounce at tombola!

At tombola, we're not just another player in the game; we're the creators of the game. Our approach is revolutionary – we craft every element of our software in-house, from concept to execution.

Within our B2B space, this means building not just the games themselves, but the platforms and services that enable other companies to integrate with and run our products. It’s about creating robust, scalable systems that power those experiences behind the scenes.

Sounds great! What will I be doing?

You will be involved in all phases of development, from conception all the way to release and beyond. Building highly available backend services that power integrations with external partners, using languages and technologies such as C#, T-SQL, DynamoDB, Redis, AWS and more.

You’ll be designing and building APIs that act as the bridge between our platform and partner systems, ensuring data flows securely and reliably.

You will actively support the implementation of continuous integration to ensure a solid deployment process, and collaborate closely with colleagues across game, product, platform, infrastructure and QA teams to deliver cohesive solutions.
