• Define scalable, secure, and high-performance system architecture to support nationwide and global expansion
• Establish standards for APIs, service communication (REST, gRPC, event-driven), and data flow across services
• Design and implement identity and access management (OAuth2, OpenID Connect, JWT)
• Drive cloud infrastructure decisions (AWS preferred), ensuring high availability, fault tolerance, and cost efficiency
• Architect
• Multi-tenant systems to support multiple products and user bases under a single platform
• Collaborate closely with Product, Engineering, and DevOps to translate business needs into technical solutions
• Conduct architecture reviews and guide teams on best practices, scalability, and system design
• Balance speed, scalability, and maintainability while making critical technical decisions
• Own and evolve the long-term architecture roadmap for the platform
• Solid understanding of distributed systems, event-driven architecture, and API gateways
• Experience with containerization (Docker) and orchestration (Kubernetes)
• Proven experience designing and scaling large, distributed platforms serving high-volume users and multiple products
• Define architectural governance, engineering standards, service ownership models, and system documentation practices
• Design strategies for observability, centralized logging, monitoring, disaster recovery, and fault isolation
• Architect secure tenant isolation, API governance, service discovery, and interoperability across platform services
• Ensure platform readiness for regional and international scale, including GCC and US market expansion
• Drive technical decision-making around performance optimization, resilience, scalability, and long-term maintainability
