KEY RESPONSIBILITIES

- Design, develop, and enhance backend services and APIs using Java and Spring Boot.
- Build high-throughput and resilient event-driven components using Kafka.

• Integrate Large Language Models (LLMs) such as OpenAI, Claude, or Gemini into backend services via REST APIs and SDKs.

- Build and maintain AI-powered microservices including RAG (Retrieval-Augmented Generation) pipelines, semantic search, and document intelligence features.
- Develop and expose AI agent workflows using frameworks such as LangChain4j, Spring AI, or similar Java- native AI toolkits.
- Implement prompt engineering strategies, context management, and output validation layers for LLM interactions.
- Design vector database integrations (Pinecone, Weaviate, pgvector) for embedding storage
- Participate in code reviews, refactoring efforts, and optimisation of system performance.
- Ensure best practices for coding standards, security, maintainability, and AI model governance.
- Troubleshoot production issues and provide root cause analysis and long -term fixes.
- Support CI/CD pipeline integration, model deployment automation, and MLOps tooling.
- Contribute to documentation, technical specifications, and architectural diagrams.
