Join the Exciting Journey at tombola! 🚀 We are seeking a Backend Game Developer for our backend development team to actively contribute to the design, development and delivery of the game engines that power our bingo products - and to adapting them for our B2B platform.
In this team, you'll be building the core game logic behind our bingo experiences as well as extending and integrating those engines so they can be delivered to external partners through our B2B APIs. Alongside the engines themselves, you'll also work on supporting systems such as chat and game certification, ensuring everything runs smoothly, securely and reliably at scale.
The role involves learning the business use case around our solutions, contributing to the development of new services, and showcasing your technical expertise in delivering backend systems that support both player-facing games and 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.
For our team, this means building the actual game engines — the bingo logic at the heart of our products — as well as the systems that let other companies integrate with and run those games. It's about creating robust, scalable engines and services 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 game engines and highly available backend services that power both our own products and B2B integrations, using languages and technologies such as C#, T-SQL, DynamoDB, Redis, AWS and more.
