About the role

We're seeking a Smart Contract Engineer to join our team in developing next-generation DeFi infrastructure. You'll be working on the design and implementation of innovative lending protocols and decentralized exchanges (DEXes). You'll collaborate on architecture, write production-grade Solidity code, run rigorous testing and fuzzing campaigns, and be involved in internal security audits.

We're looking for someone who is self-driven, proactive, and ready to take ownership of the features they build from ideation to deployment.

What You'll Do

• Design and implement core smart contracts for lending and DEX protocols
• Write high-quality, gas-efficient, and secure Solidity code
• Own end-to-end delivery of features and protocol upgrades
• Maintain a production protocol with $500M+ TVL and ensure smooth deployments
• Launch and configure new lending markets on-chain
• Write comprehensive test suites using Foundry
• Design and run fuzz testing campaigns using Echidna
• Participate in internal audits and contribute to the security posture of the protocol
• Collaborate closely on protocol architecture and product design
• Work with Certora on formal verification tasks

Requirements

• 3+ years of experience developing smart contracts in Solidity
• Strong proficiency with Foundry (including scripting, tests, forks)
• Experience with Echidna or other fuzz testing frameworks
• Solid understanding of smart contract security and common attack vectors
• Self-motivated and able to work autonomously and drive features forward
• Strong communication and problem-solving skills

Nice to Have

• Experience with formal verification tools such as Certora Prover
• Past contributions to lending protocols or decentralized exchanges
• Familiarity with Ethereum L2s or alternative EVM chains
• Open-source contributions or audit reports you can share

What We Offer

• Work on cutting-edge DeFi infrastructure with a tight-knit, experienced team.
• Flexible hours and a remote-first culture.
• High impact and ownership from day one.
• Competitive compensation in stablecoin, in addition to a generous token allocation

If you're excited about building secure, efficient, and elegant smart contracts and want to help shape the future of DeFi, we'd love to hear from you.
