About the Role

The Role: Back-End Developer (Builder, Optimizer, Game-Changer)We’re looking for a killer back-end engineer who loves tackling high-load, real-time challenges head-on.You’ll be a key part of our core team — building out APIs, scaling databases, fine-tuning performance, and making sure our platform can handle serious action without breaking a sweat.

• Security layers that keep user data (and crypto) ultra-safe

• Gaming logic and math models that are dead-on accurate and lightning fast

• Web3 integrations and next-gen features as we grow

• You’ll work shoulder-to-shoulder with front-end, DevOps, and external teams to  make it all sing.

What We’re Looking For

• Strong Node.js skills (this is your bread and butter)

• SQL, Redis, AWS experience — you know how to build at scale

• Web3 and blockchain knowledge? Big bonus points

• You get high-load systems and real-time data like second nature

• You understand the iGaming world — game engines, odds, player transactions, the works

• You actually enjoy complex math and logic problems

• You can work independently, figure things out fast, and ship without needing constant hand-holding
