• Supervise the development of core backend modules, including trading system, payment settlement system, user management system, asset management system, risk control system, and API gateway, ensuring that system functions meet business requirements and regulatory standards.
• Manage backend system iteration and maintenance work, monitor system operation status, collect and analyze system performance data, identify and solve system bottlenecks, fix online bugs in a timely manner, and continuously optimize system performance and stability.
• Coordinate with the DevOps team to build and optimize the CI/CD pipeline, improve the automation level of system deployment, testing, and operation and maintenance, reduce manual operations, and improve system deployment efficiency and stability.

3. Backend Security & Compliance Management

• Establish and improve the backend system security management system, formulate security standards and specifications, and ensure that the backend system meets data security, user privacy protection, and digital asset security requirements.
• Lead the security development of backend systems, conduct regular security audits, vulnerability scans, and penetration tests, identify and fix security risks (such as data leakage, malicious attacks, and transaction tampering), and ensure the security of user assets and transaction data.
• Ensure that backend system development and operation comply with global regulatory requirements (FATF, MiCA, local regulations), cooperate with the compliance and risk control teams to complete system compliance reviews, regulatory filings, and security assessments, and provide relevant technical materials and explanations.
• Establish a system disaster recovery plan and emergency response mechanism, conduct regular disaster recovery drills, ensure business continuity in case of system failures or emergencies.

4. Team Management & Talent Development

• Build, manage, and develop the backend development team, formulate team structure, OKRs, performance assessment standards, and talent training plans, and improve the team’s overall professional capabilities (backend development, architecture design, security development, etc.).
• Arrange daily work assignments for the team, supervise work progress, solve complex technical difficulties in the development process, and create a positive, collaborative, and high-performance technical team atmosphere.
• Guide team members’ professional growth, cultivate technical backbones and system architects, organize technical training, technical sharing, and skill assessments, and build a professional backend talent echelon.
• Manage team performance, conduct regular performance reviews, motivate team members to achieve work goals, and retain core technical talents.

5. Cross-departmental Collaboration & Technical Coordination
