- Build responsive and accessible user experiences using React and modern web development practices.
- Develop scalable backend services and APIs using Python, FastAPI/async frameworks, and Java.
- Build and integrate LLM-powered and agentic AI applications using frameworks such as LangGraph, LangChain, AutoGen, or similar technologies.
- Design Retrieval‑Augmented Generation (RAG) solutions using embeddings, vector/hybrid search, and enterprise knowledge sources.
- Build and maintain data ingestion pipelines and work with large datasets using Azure Databricks and Delta Tables.
- Develop cloud‑native applications leveraging AKS/Kubernetes, Azure API Management, Azure Service Bus, MongoDB/Cosmos DB, and vector databases.
- Establish and maintain automated build, integration, and deployment pipelines using GitHub Actions.
- Implement strong engineering practices across testing, code reviews,



observability, security, performance, and reliability.
- Troubleshoot complex production issues, conduct root-cause analysis, and drive issues through resolution.
- Partner with product, design, QA, engineering, and business stakeholders to translate requirements into effective technical solutions.
- Contribute to architectural decisions and advocate for scalable, consistent engineering standards across the stack.
- Take ownership of individual deliverables and drive work forward with minimal supervision.

What You Bring

- 3+ years of skilled software engineering experience, with strong backend and full-stack development expertise.
- Hands‑on development experience with Python, Java, and React.
- Experience developing backend services and APIs using FastAPI, asynchronous Python frameworks, or similar technologies.
- Practical experience building LLM-based or agentic AI solutions using LangGraph, LangChain, AutoGen, or comparable frameworks.
- Hands‑on experience developing RAG solutions, including embeddings, vector or hybrid search, and enterprise data sources.
- Data engineering experience with Azure Databricks, data ingestion pipelines, Delta Tables, and large datasets.
- Experience with cloud‑native technologies such as AKS/Kubernetes, GitHub Actions,



Azure API Management, Azure Service Bus, MongoDB/Cosmos DB, and vector databases.
- Strong understanding of application security, including authentication, authorization, input validation, and data protection.
- Strong verbal and written communication skills, with the ability to clearly explain technical approaches and trade‑offs to both technical and business audiences.
- A collaborative mindset combined with the ability to independently own and deliver work.

Nice to Have

- Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Software Engineering, Information Technology, or a related discipline.
- Experience with Azure AI Search, Azure OpenAI, Azure AI Foundry, or comparable AI platforms.
- Experience with intelligent document processing, including OCR, document extraction, classification, and data validation.
- Working knowledge of Model Context Protocol (MCP), tool calling, and AI integration patterns.
