Job description

I'm working with a rapidly scaling and fast moving gambling / betting company who need multiple .NET contractors with real pedigree to help power their expansion into new markets.

You'll be working on high-throughput backend systems - SignalR, real-time odds feeds, KYC and casino aggregator integrations - building out infrastructure that can be spun up in new jurisdictions with minimal effort. There's also an internal admin tool that needs deploying to new entity and, depending on your full-stack chops, potentially rebuilding from scratch.

Tech stack (required for these roles)

• Currently on .NET 9, heading to .NET 11
• Leveraging AI and automations in your day to day workflows
• SignalR
• Hosted in their Azure cloud

Wider stack (not important for these roles)

• Typescript stuff on Frontend
• Their mobile apps are all fully React Native

Gambling or fintech background is a strong plus. Proactive, self-directed contractors only - there's no one here to hand out tickets.
