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.

Senior Frontend Engineer - High-Performance Financial Platform

Location: New York, San Francisco (Office)

Compensation: $185K - $300K

We are hiring on behalf of our client who are building a revolutionary Multi-Asset Margin solution for one of the fastest-growing ecosystems in decentralized finance. Currently, the crypto derivatives sector generates $20B–$30B in annual revenue, and multi-asset margin accounts for over 86% of all trading activity. Their mission is to bridge the gap between diverse collateral types and high-performance trading.

Their platform allows users to post variable forms of collateral without needing to sell their assets for stablecoins. By building sophisticated blockchain-integrated systems "under the hood," they extend liquidity to the venues of their users' choice, bringing the market to them rather than forcing them to navigate multiple fragmented platforms.

As a member of their Product & Platform team, you will build and maintain the applications that power these services. You will collaborate closely with designers, backend engineers, and product managers to deliver responsive, high-performance user interfaces that define the future of DeFi trading.

The Frontend Engineer will be responsible for the full lifecycle of application development, focusing on performance, user experience, and real-time data visualization.
