About the Role We are seeking a Lead Full Stack Architect – Backend Focus to architect, build, and optimize high-performance, large-scale systems. This role is backend-focused but requires solid frontend problem-solving skills. You will lead development across multiple interconnected modules, ensuring the system is designed for high scalability, modular decoupling, and future feature extensibility . You’ll tackle real-world performance issues , design solutions for millions of data records with complex queries, implement efficient caching strategies , and handle high-frequency API traffic without system degradation. Your work will directly influence system reliability, developer productivity, and overall product scalability . Key Responsibilities Backend Leadership Lead architecture and development for backend-heavy, modular systems. Design solutions for large datasets (millions of records) with multi-level joins, nested sorting, and pagination . Implement fault-tolerant designs to avoid infinite loops, bottlenecks, or cascading failures under high-frequency requests. Drive performance optimization , caching strategies (Redis, in-memory), and query tuning. Full Stack Contribution Solve complex frontend challenges when needed (React/Next.js preferred). Build dynamic, data-driven UIs capable of handling large paginated datasets efficiently. System Scalability & Maintainability Design architecture that allows modules to be tightly integrated yet easily decoupled for future replacements or upgrades. Write maintainable, modular, and clean code with clear documentation . Monitoring & Debugging Implement real-time monitoring and logging for performance tracking. Diagnose and resolve production incidents , including “API success but null response” and CPU spikes. Mentorship & Code Quality Review pull requests for performance, security, and scalability considerations. Mentor developers in backend best practices and advanced SQL/NoSQL optimizations. Requirements Technical Skills Backend Expertise : 5+ years in Node.js or NestJS with deep knowledge of event loops, async patterns, clustering, and process management. Expert in SQL databases (PostgreSQL/MySQL/SQL Server) with query optimization, indexing, and execution plan analysis . Experience in large-scale API design , pagination strategies, and cache invalidation logic. Frontend Knowledge : Proficient with React.js / Next.js and state management (Redux, Zustand, etc.). Understanding of performance optimization in frontend rendering with large datasets. Architecture & Scalability : Designing decoupled, modular architectures capable of being restructured without major rewrites. Experience with message queues, microservices, and distributed systems. Performance & Monitoring : Redis/memcached caching at scale. Strong debugging skills with tools like New Relic, Datadog, or custom monitoring solutions. Soft Skills Strong problem-solving mindset for real-world production scenarios . Ability to lead a team and set technical direction. Excellent communication skills for cross-functional collaboration. Nice to Have Experience with multi-tenant architectures . Knowledge of containerization (Docker, Kubernetes). Familiarity with high-traffic systems (100k+ requests per minute).
The Lead Full Stack Architect Backend Focus is responsible for architecting, building, and optimizing high-performance, large-scale systems with a backend focus, while also possessing strong frontend problem-solving skills. You will be leading development across multiple interconnected modules to ensure scalability, modular decoupling, and future feature extensibility of the system. Your responsibilities include leading architecture and development for backend-heavy, modular systems, designing solutions for large datasets with complex queries, implementing fault-tolerant designs, and driving performance optimization and caching strategies. Additionally, you will contribute to solving frontend challenges, building dynamic UIs, and designing architectures for system scalability and maintainability. Monitoring and debugging are vital aspects of the role, where you will implement real-time monitoring and logging for performance tracking, diagnose and resolve production incidents, and mentor developers in backend best practices and advanced SQL/NoSQL optimizations. Your expertise in Node.js or NestJS, SQL databases, frontend technologies like React.js/Next.js, and architecture & scalability principles will be crucial for success in this role. The ideal candidate should possess strong problem-solving skills for real-world production scenarios, the ability to lead a team and provide technical direction, and excellent communication skills for cross-functional collaboration. Experience with multi-tenant architectures, containerization, and high-traffic systems would be advantageous.,
