- Establish and document API standards (naming, authentication, versioning, pagination, error handling, etc.) and drive consistent adoption across teams.
- 🔹 Multi-Currency and Cross-Border Enablement
- Ensure the API layer is designed to support multiple currencies, jurisdictions, and transaction types (e.g., wallet-to-wallet, bank-to-wallet, crypto conversions).
- Work closely with compliance and legal to embed country-specific regulatory requirements into API behavior where applicable.
- 🔹 Developer Experience & Ecosystem
- Champion the developer experience, ensuring that APIs are intuitive, well-documented,and easy to test and integrate.
- Lead the creation of developer portals, sandbox environments, and tools for external and internal API consumers.
- 🔹 Monitoring, Governance & Lifecycle Management
- Define success metrics (API adoption, latency, error rates) and collaborate with engineering to set up dashboards and monitoring.
- Oversee API versioning, deprecation strategy, and long-term maintainability.
Qualifications
- Bachelor's or Master’s degree in Computer Science, Engineering, or related field.
- 7+ years of product management experience, ideally with 3+ years in API/platform product roles in fintech, payments, or SaaS.
- Strong understanding of RESTful API design, OAuth2/security standards, and backend systems.
- Experience working with multi-currency, multi-jurisdictional financial products is a strong plus.
- Excellent cross-functional communication skills; ability to write clear product specs and manage competing priorities.
- Passion for simplifying complex systems and delivering seamless developer experiences.
- Be fluent in both English and Mandarin.
Why Join Us
- Be part of the global regulated leading crypto and digital payments company.
- Help build a next-generation payment infrastructure with real-world impact.
