Roles and Responsibilities

Backend Development

● Design and implement mission-critical backend services in Java (8+) and Spring Boot.
● Build real-time APIs for telemetry, inventory synchronization, and payment reconciliation.
● Ensure services meet <200ms latency targets and scale to 100K+ concurrent connections.
● Write clean, maintainable, and testable code following best practices.

DSA & Problem Solving

● Apply advanced algorithms for concurrency control, distributed caching, lock- free data structures, and event-driven workflows.
● Resolve performance bottlenecks in systems processing millions of events/day.
● Conduct Big-O complexity analysis to optimize time and space efficiency.

System & Backend Design

● Architect microservices-based, event-driven systems with guaranteed delivery (Kafka/RabbitMQ).
● Design for zero-downtime deployments and multi-region failover strategies.
● Create efficient database schemas, sharding strategies, and indexing for high- volume transactional systems.
● Define API contracts, inter-service communication, and observability standards.

Qualifications

● Strong proficiency in Java (8+) and Spring Boot.
● Expertise in REST API design and SQL/NoSQL databases (Postgres, MongoDB).
