About the Role
We're looking for a Full Stack Engineer with a strong foundation across front-end, back-end, and AI/ML technologies to join a forward-thinking engineering team. In this role, you'll build and maintain web applications powered by modern frameworks while integrating cutting-edge AI capabilities — including Large Language Models (LLMs) and agentic AI patterns — into real-world business workflows. If you enjoy working across the entire stack and are excited about bringing AI from prototype to production, this is the role for you
What You'll Do
- Build & maintain fron t-end interfaces using Angular (or equivalent component-based frameworks), delivering clean and responsive user experiences.
- Develop back-end services in Java 21+ and Spring Boot, including REST APIs, data persistence with Spring Data JPA, and foundational security with Spring Security
- Design and manage database interactions with Oracle Database — writing optimized SQL, managing joins, indexing, stored procedures, and JPA/Hibernate entity mappings.
- Architect and document RESTful APIs following best practices, with clear documentation via OpenAPI/Swagger.
- Build and deploy AI/ML pipelines in Python, leveraging LLM orchestration frameworks (LangChain, LangGraph, LlamaIndex, or similar) and serving them through FastAPI or equivalent frameworks.
- Integrate LLM APIs (OpenAI, Azure OpenAI, Anthropic, Cohere, etc.) into applications using prompt engineering best practices.
- Implement agentic AI patterns including tool-calling, function calling, ReAct workflows, Retrieval-Augmented Generation (RAG), and vector store integrations.
- Translate ambiguous b usiness problems into clear technical requirements by interpreting SOPs, process documents, and workflow diagrams.
- Collaborate cross-functionally in an Agile team environment, communicating technical concepts clearly to non-technical stakeholders
