Total Experience : 3 - 5 years

Technical Expertise to Look For :

- Deep Java & Spring Boot Knowledge : Proven experience in building and scaling secure, high-performance RESTful APIs and microservices using Java and the Spring Boot framework, with familiarity with Spring Cloud distributed systems as a plus.

- Expert-Level Relational Databases (e.g., PostgreSQL, MySQL) : Strong data modeling skills, extensive experience with optimizing complex queries, and a deep understanding of database security features, including indexing strategies, transaction management, connection pooling, and replication.

- Authentication & Authorization : Hands-on experience implementing complex Identity and Access Management (IAM) concepts such as OAuth 2.0, OpenID Connect (OIDC), SAML, JWT, and role-based access control (RBAC).

- Security Best Practices : A security-first mindset with experience in data encryption (at rest and in transit), hashing algorithms (e.g., bcrypt, scrypt), and preventing common vulnerabilities (e.g., SQL injection, XSS, CSRF, insecure deserialization).

- Unit & Integration Testing : Proficiency with testing frameworks like JUnit, Mockito, and Spring Test, as well as experience with integration testing and end-to-end testing methodologies.

- Caching & Messaging : Experience with caching mechanisms (e.g., Redis, Memcached) and message brokers (e.g., Kafka, RabbitMQ) for building highly performant and scalable systems.

Role & Responsibilities :

- Architect and build the core backend services, including robust user authentication, session management, and access control logic.

- Design and optimize relational database schemas, ensuring scalability, high availability, and robust security.

- Write critical, high-performance, and maintainable Java code, setting the standard for the backend codebase.

- Lead a "Backend Pod" for 3 - 4 junior to mid-level developers, fostering a collaborative and productive environment.

- Conduct thorough code reviews to enforce best practices in coding standards, security, performance, and API design.

- Mentor junior developers on advanced Java backend development principles, efficient database interactions, and secure API design.

- Break down complex backend features and tasks into manageable stories and subtasks for the development team.
