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.
