• Build in-house Solana and/or EVM blockchain indexing infrastructure

• Design high-performance, cost-efficient data serving and caching using PostgreSQL and AWS/GCP
• Lead backend architecture and platform feature development alongside the founder and product lead

• Approximately 6-12 years of backend engineering experience; 8-12 is ideal
• 2-3+ years of recent crypto experience
• Experience building backend systems for a crypto exchange, DEX, wallet, brokerage, trading terminal, or similarly demanding product
• Strong production expertise in Rust or Go
• Hands-on experience indexing Solana or EVM on-chain data
• Experience with WebSockets / real-time data at scale
• PostgreSQL and AWS or GCP
• Strong 0-1 ownership and comfort working in a very small, highly autonomous engineering team
