Go Developer

Design and build low-latency services for order matching, risk checks, and settlement. Optimize hot paths using profiling, lock-free data structures, and careful memory management. Integrate with blockchain nodes (Bitcoin, Ethereum, Solana, and L2s) for deposits, withdrawals, and on-chain confirmations. Build internal APIs (gRPC, WebSocket, REST) consumed by web, mobile, and institutional clients. Participate in on-call rotation and help maintain five-nines uptime on critical services. Collaborate with quant, security, and compliance teams on new product launches.

Nice-to-Haves

• Prior experience at a crypto exchange, prop trading firm, or HFT shop
• Contributions to open-source Go projects
• Rust or C++ for performance-critical components
• Knowledge of order book mechanics, FIX protocol, or market microstructure
