Job description

Our goal is to have full control over the architecture, trading logic, performance, and product development instead of relying on third-party exchange solutions.

This role is focused on high-performance backend development for the exchange core and surrounding ecosystem.

  • Integrating the platform with crypto processing providers (Fireblocks, BitGo, Copper, Alchemy Pay and similar)
  • Building scalable and secure services for digital asset trading
  • Contributing to the architecture of a next-generation trading platform

Requirements

  • 5+ years of experience with C# / .NET backend development
  • Strong experience building high-load or low-latency systems
  • Experience with multithreading, concurrency and performance optimization
  • Background in trading systems, exchanges, banking, gaming or other high-throughput platforms
  • Experience integrating with crypto processing or custody providers (Fireblocks, BitGo, Copper, Alchemy Pay, etc.)
  • Strong system design and backend architecture skills

Tech stack

  • C# / .NET (latest versions)
  • High-performance backend architecture
  • In-memory processing
  • Modern infrastructure and cloud tooling
