Description

  • Design preventive, real-time, and detective controls to protect funds across deposit, withdrawal, and trading flows.
  • Build account security controls, including account-status management, fund freezing and unfreezing, sensitive-operation protections, and abnormal-behavior detection.
  • Integrate with banks and third-party payment providers, ensuring reliable callbacks, status synchronization, idempotency, and retries.
  • Collaborate with internal accounting, clearing, and settlement teams to align fund flows with the ledger and define accounting models and fund-flow standards.
  • Build and automate channel, internal, and multi-party reconciliation processes, including break detection, suspense-account handling, and adjustments.
  • Develop reconciliation checks and fund-loss alerts; lead investigation, containment, and post-mortems for fund-related incidents.
  • Apply LLMs and AI tools to anomaly detection, reconciliation, root-cause analysis, and operations support.

Requirements

  • 5+ years of experience in financial services, such as payments, banking, or exchanges, with hands-on fund-security and reconciliation experience.
  • Expertise in Java, JVM internals, concurrency, distributed systems, and highly available, strongly consistent systems.
  • Experience with Spring Boot, Spring Cloud, MyBatis, MySQL, Redis, Kafka, or RocketMQ.
  • Experience designing and delivering end-to-end financial systems using distributed transactions, idempotency, and eventual consistency.
  • Knowledge of clearing and settlement processes, double-entry bookkeeping, and bank-integration methods including APIs, SFTP reconciliation files, ISO 20022, and SWIFT messages.
  • Hands-on experience building LLM applications, including prompt engineering, RAG, and agents, and using AI tools daily.
  • Strong risk awareness, attention to detail, ownership, and communication skills.
  • Bilingual English and Mandarin, with ability to coordinate with overseas partners and stakeholders.

Benefits

  • Competitive salary and company benefits.
  • Remote-first, work-from-home arrangement, depending on role and team needs.
  • Career-growth and continuous-learning opportunities.
  • Autonomy to work on challenging projects in a fast-paced environment.
  • Collaboration in a global organization with a flat structure.
