Senior Java Developer-Early Joiner

Role & responsibilities

Critical Requirement: Proficiency with AI coding tools (GitHub Copilot, Cursor, Augment Code, etc.) to accelerate development while maintaining high code quality.

Required Technical Skills

• AI-Assisted Development(*) - Daily use of AI coding tools (GitHub Copilot, Cursor, Augment Code) for code generation, refactoring, testing, debugging, and documentation to achieve 10x development velocity while balancing AI assistance with critical thinking.
• OAuth 2.0 & Enterprise Authentication - Implement OAuth 2.0 flows (Authorisation Code, Refresh Token, Client Credentials) with token management for Google APIs, Microsoft Graph, Salesforce, SailPoint, ServiceNow, Okta, and enterprise SSO protocols (SAML, OIDC).
• RESTful API Integration - Build integrations with enterprise APIs (Google Workspace, Microsoft 365, Salesforce, SailPoint,ServiceNow, Workday) using third-party Java SDKs with rate limiting, pagination, retry logic, and asynchronous/GraphQL patterns.
• Annotation-Based Framework Development - Design custom annotation-based frameworks using Java annotations,annotation processors, JAX-RS/Jersey, and compile-time code generation with reflection.
• Dependency Injection (HK2/Guice/Spring) - Implement loosely coupled architectures using dependency injection patterns

(@Inject, @Service) with scope management and factory patterns.

• Validation & Error Handling - Build multi-layered validation frameworks with error categorisation (INPUT_ERROR, LOGIC_ERROR, SYSTEM_ERROR), retry mechanisms, and remediation workflows.
• Webhook & Event-Driven Architecture - Develop webhook receivers with subscription management, asynchronous event processing, delta queries using ExecutorService and thread pools.
• Telemetry & Monitoring - Implement comprehensive metrics collection, structured logging (SLF4J, Log4j), distributed tracing,

and performance monitoring.

• State Management & Caching - Design distributed state management with token caching and thread-safe data structures for concurrent access.
• Asynchronous Processing - Master Java concurrency (ExecutorService, CompletableFuture) with thread pool management and deadlock prevention strategies.
• Documentation & Developer Experience - Create comprehensive technical documentation (Markdown, Docsify),
• API documentation and Javadoc using AI-assisted documentation tools.
