Java Developer – Spring Boot, AWS & AI Integration

Job Title: Senior Java Developer

Responsibilities Design and implement RESTful APIs and backend services on Spring Boot; maintain or extend Spring MVC where the product still uses it. Work with Oracle: development aligned to existing schemas, tuning of queries and procedures for transactional and reporting workloads; collaborate on data modelling with the team. Participate in HR / Payroll delivery: workflows, validations, and integrations—with appropriate care for PII and pay data. Contribute to LLM-augmented features in a governed way: tool/function use with clear boundaries, retrieval / grounding on approved internal data, observability, and adherence to enterprise security and compliance—not ad-hoc prompt-only scripts. Write concise technical designs, unit and integration tests where they add value; take part in code reviews and production troubleshooting.

Requirements 3–5 years of professional experience building backend systems in Java, including Spring Boot services in production. Bachelor’s degree or above; computer-related or equivalent field. Strong Java and a solid grounding in core APIs, concurrency, and service structure. Solid REST API design (errors, versioning, idempotency where relevant, auth aligned with platform). Strong Spring Boot and Spring MVC in real systems. Hands-on Oracle: SQL and PL/SQL as needed; basics of performance. Exposure to HR, HCM, or Payroll is a plus; sensitivity to PII/pay and regulated processes matters. Beyond using AI as an end user: practical involvement in LLM-augmented systems—e.g. orchestration, tool/function calling, grounding on internal data, evaluation or production monitoring. Able to debug and own problems through to resolution; works well in a team with clear written communication and willingness to pick up unfamiliar areas.

Nice-to-haves Spring AI, vector databases, or integration with external model providers under enterprise constraints. Event-driven architecture; Kafka or RabbitMQ. Cloud (e.g. AWS), CI/CD, containers. Payroll engines, localization, or statutory filings in relevant geographies.
