Job Summary We are seeking a hands-on, high-impact Senior Technical Architect (Platform Backend) to lead the architecture, scaling, and continuous evolution of our core platform infrastructure. In this role, you will operate at the intersection of high-throughput transactional systems and cloud-native architecture. You will be responsible for driving high-level and low-level designs (HLD/LLD), establishing engineering guardrails, optimizing complex data pathways, and collaborating directly with product and engineering leaders to ensure absolute reliability, performance, and low latency at scale. Key Responsibilities: System Design Architectural Leadership: Own the end-to-end High-Level Design (HLD) and Low-Level Design (LLD) for core platform services, asynchronous processing components, and enterprise ERP/bank integration adapters. Facilitate a smooth transition from monolithic legacy boundaries into clean, highly cohesive microservices domains without impacting uptime or data integrity. Establish architectural governance, lead Architecture Review Boards (ARBs), and review critical pull requests to safeguard code quality, clean architecture principles, and SOLID design patterns. Scalability, Performance Reliability: Architect multi-tenant, cloud-native frameworks capable of handling high-concurrency and petabyte-scale financial transactions with strict SLAs.
