Smart Contract Engineer (Rust) - High-Performance DeFi Infrastructure

Location: PST-CAT preference

Compensation: Competitive

We are building the next generation of Decentralized Finance (DeFi) liquidity infrastructure on the Solana blockchain. We are solving a critical industry problem where reliance on over-collateralized lending leads to inefficient capital use, fragmented systems, and unnecessary liquidation risks.

Our solution introduces under-collateralized borrowing, programmable margin accounts, and composable on-chain strategies ("Recipes"), all built with high-performance Rust smart contracts. We are redefining how liquidity moves in DeFi: faster, safer, and more capital-efficient.

We are looking for a highly capable Smart Contract Engineer (Rust) to join our core engineering team and shape the technical backbone of our protocol. You will design, build, and optimize Rust-based smart contracts that power our DeFi infrastructure, working closely with product and protocol teams to create scalable, secure, and innovative financial primitives.

As a core contributor, you will take full ownership of your work, from concept and research to mainnet deployment and maintenance.
