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
