Senior Java Backend & Database Lead (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. Familiarity with Spring Cloud distributed systems is 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. Crucial knowledge includes 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. 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.
