A high-growth, venture-backed crypto company is hiring a Staff Backend Engineer to help build next-generation autonomous trading infrastructure.

This is a senior, ownership-heavy role working on real-time trading systems, wallets, and execution infrastructure operating under extreme market conditions. The client is highly responsive and only interviewing candidates who meet all criteria.

• Shipping production systems with a strong bias toward correctness, resilience, and speed
