About the job

Key Responsibilities: • 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.
