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.
