Lead Blockchain Developer
Location: Hybrid Employment Type: Full-time Experience Required: 10+ years (software engineering), with 5+ years in blockchain/Web3 development Position: Multiple
About the Role
We're looking for a Lead Blockchain Developer to drive the architecture, security, and delivery of our Ethereum-based smart contract systems and decentralized applications. This is a hands-on technical leadership role: you'll write and review production Solidity code, set engineering standards, and mentor a team of blockchain engineers while partnering closely with product, security, and infrastructure stakeholders. You'll own technical decisions from protocol design through mainnet deployment and ongoing maintenance.
Key Responsibilities
- Architect, design, and lead development of smart contracts and on-chain protocols on Ethereum and EVM-compatible chains, ensuring scalability, gas efficiency, and security best practices.
- Lead the full development lifecycle: technical design, implementation, code review, testing, audits, deployment, and post-launch monitoring.
- Mentor and manage a team of blockchain developers, setting coding standards, conducting code reviews, and guiding career growth.
- Collaborate with product managers, designers, and backend/frontend engineers to translate business requirements into robust on-chain and off-chain solutions.
- Own smart contract security practices, including coordinating third-party audits, running internal threat modeling, and implementing fixes for identified vulnerabilities.
- Evaluate and integrate relevant standards and tooling (e.g., ERC-20/721/1155, OpenZeppelin, Hardhat/Foundry, The Graph) and stay current on EVM upgrades and Ethereum roadmap changes.
- Design and oversee upgrade patterns, multisig/governance structures, and key management practices for deployed contracts.
- Establish CI/CD pipelines, testing frameworks (unit, integration, fuzz/invariant testing), and monitoring for on-chain systems.
- Represent the engineering team in technical discussions with auditors, partners, and external stakeholders.
Required Qualifications
- 10+ years of professional software development experience, including 5+ years building production Solidity smart contracts on Ethereum or EVM-compatible chains.
- Proven track record leading or architecting blockchain projects from design through mainnet launch.
- Deep understanding of EVM internals, gas optimization, and common smart contract vulnerabilities (reentrancy, integer overflow, access control, oracle manipulation, etc.).
- Hands-on experience with Solidity development frameworks such as Hardhat, Foundry, or Truffle, and testing/fuzzing tools.
- Strong knowledge of token standards (ERC-20, ERC-721, ERC-1155), DeFi primitives, and/or DAO governance mechanisms, depending on product focus.
- Experience with smart contract security practices, including working alongside auditors and remediating findings.
- Solid background in at least one general-purpose language (TypeScript, JavaScript, Go, Rust, or Python) for building supporting infrastructure and tooling.
- Experience leading or mentoring engineers, with the ability to set technical direction and review others' code constructively.
- Familiarity with Web3 libraries (ethers.js, web3.js, viem) and node infrastructure (Infura, Alchemy, or self-hosted nodes).
Preferred Qualifications
- Experience with Layer 2 solutions (Optimism, Arbitrum, Base, zkSync) or cross-chain bridging.
- Contributions to open-source blockchain projects or published smart contract audits.
- Familiarity with formal verification tools (Certora, Slither, MythX).
- Experience with on-chain governance, multisig frameworks (Gnosis Safe), or DAO tooling.
- Background in financial systems, DeFi protocols, or regulatory considerations around digital assets.
What We Offer
- Competitive salary and equity package
- Comprehensive health, dental, and vision coverage
- Flexible hybrid work schedule
- Professional development budget and conference attendance
- A high-ownership role shaping the technical direction of our blockchain products
How to Apply
Linkedin profile is mandatory.
USA, Canada or Europe Candidates are preffered.
Interested candidates should submit a resume along with links to relevant GitHub repositories, deployed contracts, or audit reports demonstrating prior work within next 20 days through [email protected]
How do I get a job at DeFi?
Getting a job in the DeFi (decentralized finance) industry can be a competitive process, but there are a few steps you can take to increase your chances of finding a job in this field:
- Build up your skills and knowledge: To work in DeFi, you'll likely need to have a strong understanding of blockchain technology, as well as other related technologies such as smart contracts and cryptocurrency. Consider taking online courses or earning a degree in a relevant field to build up your skills and knowledge.
- Network with industry professionals: Attend meetups and conferences related to DeFi and make connections with professionals in the industry. Networking can be a valuable way to learn about job openings and get your foot in the door at a DeFi company.
- Create a strong online presence: Many DeFi companies will look at your online presence (such as your LinkedIn profile and personal website) when considering you for a job. Make sure to showcase your skills and accomplishments online and keep your profile up to date.
- Apply for relevant job openings: Keep an eye out for job openings at DeFi companies and apply for positions that align with your skills and experience. Apply for DeFi Jobs without Experience. Tailor your resume and cover letter to the specific job you're applying for and highlight any relevant experience or skills you have.
- Consider internships or volunteer work: DeFi Internships or volunteer work can be a great way to get your foot in the door and gain valuable experience in the DeFi industry. Many companies also offer internships to students, so consider applying for an internship if you're still in school.
- Be persistent: keep trying if you don't get a job right away. It can take time to find the right opportunity, but with the right skills and determination, you can land a job in the DeFi industry.
