Lead Engineer, Custody Engineering (Tokenization)

Skills

About the Role

You will own the technical roadmap for tokenization and scale the foundational architecture. You will drive asset issuance, controlled transfer, settlement mechanics and on chain verification. You will oversee secure design, implementation and audits of the smart contracts that hold customer assets and the backend for workflows interacting with the contracts. You will define and enforce auditable security controls meeting institutional standards. You will act as the primary cross functional technical interface translating cryptographic and security requirements into actionable engineering work for engineering product and operational compliance teams. You will mentor a team of engineers and uphold high standards for code quality, security review and engineering judgment.

Requirements

• 6+ years of experience architecting and scaling production grade systems.
• Proven ability to lead cross functional technical initiatives and mentor high performing engineering teams to deliver high impact solutions.
• Expert level fluency in secure public chain smart contract development such as Solidity and the Ethereum Virtual Machine (EVM) with command of industry standard security frameworks and libraries such as OpenZeppelin.
• Deep authoritative knowledge of token standards (e.g. ERC-20 ERC-3643 Token-2022) and advanced wallet and custody architectures (e.g., ERC-4337 Account Abstraction, Gnosis Safe).
• Strong command of architecting secure off chain services (e.g. in TypeScript), APIs, and event indexers.
• Hands-on depth with modern Web3 development and testing frameworks (e.g., Foundry, Hardhat) and interaction libraries (e.g., Viem, Ethers.js).
• A paranoid security mindset, with proven expertise preventing and mitigating common smart contract vulnerability patterns (re-entrancy, oracle manipulation, access control flaws), use of static analysis and fuzzing tools, and a track record of leading teams through smart contract audits.
• The ability to communicate protocol logic and security trade-offs to both technical and non-technical stakeholders across global teams.
• Degree in Computer Science, Engineering, or a related technical field (or equivalent professional experience).

Responsibilities

• Lead the evolution of the foundational architecture and engineering roadmap for tokenization.
• Own the full tokenization lifecycle including asset issuance controlled transfer and on chain verification.
• Lead the secure design implementation and audit of the smart contracts that hold customer assets and the backend for workflows interacting with the smart contracts.
• Define and enforce auditable security controls that meet institutional standards for asset safety and regulatory compliance.
• Act as the primary cross functional technical interface translating cryptographic and security requirements into actionable engineering work for engineering product and operational compliance teams.
• Mentor engineers and set the standard for code quality security review and engineering judgment.
