Solidity / EVM Developer Needed – DeFi Project
"About The Role"
About This Role
This isn't a greenfield experiment—Zendarox Vault is an active, production-grade smart contract system that real users depend on. You'll be stepping into a codebase where your contributions to decentralized ledger architecture directly impact protocol performance, security, and user trust. If you thrive on solving complex on-chain logic puzzles and want your work to matter in the crypto ecosystem, this is your opportunity.
What You'll Be Doing
Architect, refine, and extend Solidity smart contracts powering our DeFi vault and yield-routing mechanisms
Build and maintain robust Foundry test suites to catch vulnerabilities before they hit mainnet
Conduct thorough security reviews and debugging passes across lending protocol logic
Optimize gas efficiency and smart contract performance across EVM-compatible chains
Bridge backend (Node.js/TypeScript) and frontend (React) systems with on-chain contract calls
Collaborate closely with the core team to iterate on protocol upgrades and new feature rollouts
What We're Looking For
Proven hands-on Solidity development experience, ideally within live DeFi or decentralized applications
Strong command of Foundry for testing, scripting, and contract deployment workflows
Solid understanding of EVM internals, gas optimization, and common smart contract vulnerabilities
Working proficiency in TypeScript, Node.js, and React for full-stack blockchain integration
A security-first mindset—you think like an auditor, not just a builder
Ability to work independently while communicating clearly with a distributed team
Bonus Points
Prior contributions to lending protocols, yield aggregators, or vault-style DeFi systems
Experience with formal verification tools or third-party smart contract audits
Familiarity with Layer 2 scaling solutions and cross-chain architecture
Active involvement in open-source web3 projects or crypto developer communities
Why Join Us
Competitive compensation with potential token/equity upside tied to protocol growth
Flexible working arrangements within a fast-moving, tech-driven environment
Direct influence over a live decentralized finance product used by real crypto participants
Continuous learning alongside experienced blockchain engineers in a rapidly evolving space
