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.

Contract Design & Implementation: Design, implement, and deploy sophisticated smart contracts in Rust for our Solana-based protocol.

Protocol Development: Support the design, development, and deployment of new on-chain features, continuously seeking innovative solutions to complex DeFi and protocol challenges through rigorous experimentation.

System Architecture: Architect systems with a laser focus on security, scalability, resilience, and gas efficiency.

Collaboration & Iteration: Work collaboratively across engineering, product, and research teams to refine, test protocol logic, and ship high-impact features.

Tooling & Ecosystem: Contribute to developer tooling, SDKs, and integration layers that empower both internal and external builders to utilize the protocol.

Production Operations: Deploy, monitor, and operate on-chain services in production, ensuring performance and reliability.

Must Have Experience: Minimum 2–4 years of professional software development experience.

Web3 & Rust: 1–3 years working with Rust and other Web3 technologies.

Smart Contract Shipping: Proven experience shipping smart contracts that handle real funds in production.

Blockchain Fundamentals: Strong understanding of blockchain architecture and secure smart contract design principles.

Mindset: Ownership mindset and the ability to move fast in an experimental, high-impact environment.

Passion: Strong passion for DeFi, on-chain innovation, and open-source development.

Nice to Have Experience with Solana, Anchor , or other Rust-based blockchain frameworks.

Contributions to open-source DeFi or protocol codebases.

Background in financial systems, derivatives, or risk management logic.

Previous experience in a startup or early-stage Web3 team.

We offer a competitive compensation structure that ensures alignment with the platform's long-term success and growth.

Compensation: Competitive Base Salary

Incentives: Token/Equity package (details provided upon offer)
