• At least 5 years of software engineering experience, including significant backend development experience.
• At least 3 years of hands-on blockchain or distributed ledger technology experience.
• Strong in TypeScript/Node.js, Java, Solidity; experience building APIs, microservices, and secure systems.
• Understanding of digital asset lifecycle (custody, wallets, tokenisation, settlement, reconciliation) and blockchain fundamentals.
• Experience with distributed system design and on-chain/off-chain architectures, including data consistency and integration patterns.
• Familiar with CI/CD, Docker, Kubernetes, cloud platforms, and operating production systems with observability and SLAs.

Preferred Qualifications

• Experience working in a bank, fintech, capital markets firm, payments company, or regulated financial institution.
• Experience working in asset tokenisation, tokenised deposits, stablecoins, CBDCs, purpose-bound money, payments, settlements, custody and related.
• Knowledge of Singapore financial services regulations, technology risk expectations, or MAS-aligned control environments.
• Familiarity with cloud platforms such as AWS, Azure, or Google Cloud.
