Vault Infrastructure Engineer

We are seeking a Vault Infrastructure Engineer to develop institutional-grade Web3 vault asset management infrastructure. The project will use smart contract-based pooled vaults and multi-party computation (MPC) custody technology to automate yield generation, tokenized asset pooling, and treasury security. It is a new 3-year R&D project, funded under the Innovation and Technology Fund (ITF) Research Talent Hub (RTH-SPC).

Key Responsibilities

• Research vault architectures for pooled asset management and related yield-generation strategies.
• Design smart contracts for vault share issuance, deposits and redemptions, rebalancing, fee mechanics, and strategy allocation.
• Develop APIs to integrate vault workflows with custody, accounting, and reporting systems.
• Implement MPC-based treasury infrastructure: threshold-signature signing, quorum policies, address whitelists, withdrawal limits, and transaction-monitoring mechanisms.
• Build prototypes and test cases covering depeg events, oracle failures, emergency withdrawals, circuit breakers, and exceptions.
• Evaluate alternative blockchain architectures, vault standards (e.g., ERC-4626), and settlement mechanisms.
• Document research findings, technical specifications, risks, limitations, and test results.
• Present prototypes and findings to management and business stakeholders.

Requirements

• Bachelor's or Master's degree in Computer Science, Financial Technology, Information Systems, Engineering, or a related discipline.
• Understanding of blockchain, digital assets, distributed ledger technology, and smart contracts.
• Programming experience in Solidity, JavaScript, TypeScript, Python, Rust, or Go.
• Knowledge of token and vault standards, APIs, wallet integration, and smart-contract security.
• Exposure to MPC/threshold-signature custody or institutional wallet infrastructure is an advantage.
• Experience in DeFi, asset management, treasury operations, or financial services is an advantage.
• Strong analytical, problem-solving, and documentation skills.
• Hong Kong permanent resident or holder of a valid visa permitting full-time employment in Hong Kong.
