Job Description

We are seeking a Java Technical Lead who is deeply strong in system design, design patterns, and backend architecture. You will own the technical direction of critical backend services, define architectural standards, and lead a team of engineers to build scalable, resilient, and high-performance systems. Key Responsibilities - Own end-to-end system design and architecture for key backend services and platforms. - Define and drive system architecture decisions: service boundaries, decomposition strategies, integration patterns, and data models. - Apply and institutionalize design patterns and architectural styles (layered, hexagonal, DDD, CQRS, event-driven, etc.). - Lead design and implementation of scalable microservices, APIs, and event-driven systems (REST/gRPC/GraphQL as needed). - Create and maintain design documents, architecture diagrams, sequence diagrams, and API contracts. - Conduct rigorous design reviews and code reviews; ensure adherence to architectural and coding standards. - Mentor senior, mid, and junior engineers on clean design, modularity, performance, and reliability. - Partner with product, frontend, QA, DevOps, and SRE to translate business requirements into robust technical solutions. - Drive non-functional requirements: scalability, latency, throughput, availability, resilience, observability, and security. - Define technology standards, evaluate new tools/frameworks, and contribute to the long-term architecture roadmap. - Lead incident analysis and post-mortems from an architectural and system-design perspective.



Must-Have Skills - 12+ years of strong Java backend development experience; 2+ years in a lead / tech lead / architect capacity. - Expert-level understanding of object-oriented design, design patterns, and system design principles. - Proven track record of designing large-scale distributed systems and microservices architectures. - Deep expertise with Spring Boot, Spring Framework, and the Spring ecosystem (Spring Cloud, Spring Data, Spring Security, etc.). - Robust command of data structures & algorithms and their impact on system performance and design choices. - Extensive experience in API design (REST; gRPC/GraphQL is a plus) and service-to-service communication. - Solid knowledge of databases (SQL/NoSQL), indexing, transactions, caching (Redis, etc.), and messaging (Kafka/RabbitMQ/SQS). - Hands-on with concurrency, async processing, and performance tuning in Java. - Ability to produce clear design docs, architecture diagrams, and sequence diagrams and walk teams through them. - Strong leadership, communication, and stakeholder management skills. Good-to-Have - Experience with domain-driven design (DDD), event sourcing, or CQRS in production systems. - Exposure to cloud platforms (AWS/Azure/GCP) and cloud-native patterns (serverless, containers, Kubernetes). - Background in high-scale domains: fintech, payments, trading, BFSI, or large-scale SaaS. - Experience setting up or contributing to architecture councils, design guilds, or internal tech forums. - Familiarity with observability stacks (metrics, logging, tracing) and SRE practices.
