We are seeking a forward-thinking AI Software Engineer to design, build, and scale intelligent applications powered by modern AI technologies. This role goes beyond traditional software engineering — focusing on Generative AI, Retrieval-Augmented Generation (RAG), and AI-assisted development using tools like Claude, GPT, and other LLM platforms.

You will play a key role in shaping our AI roadmap by building production-grade AI systems, optimizing developer productivity with AI tools, and integrating intelligent workflows into our healthcare platforms.

• Design and implement RAG (Retrieval-Augmented Generation) pipelines using modern vector databases and embeddings.
• Build and optimize LLM-powered applications (chatbots, copilots, automation agents).
• Leverage tools like Claude, GPT, and AI coding assistants to accelerate development and improve code quality.
• Develop agentic AI workflows using frameworks that enable reasoning, tool usage, and multi-step decision-making.
• Design and orchestrate multi-agent workflows including orchestrator/supervisor patterns, agent handoffs, and tool routing

• Architect and deploy AI solutions using Azure AI Foundry / Azure OpenAI / Azure ML.
• Manage scalable deployments using Azure Kubernetes Service (AKS), Docker, and Helm.
• Implement semantic search and vector indexing using tools like Qdrant or Azure Cognitive Search.
• Build model-agnostic AI routing layers ( this is to abstract the LLM provider dependencies and create pipelines where we can change models on the fly)

• Build and maintain full-stack applications integrating AI services:
  • Frontend: Angular / modern JS frameworks
  • Backend: FastAPI, Spring Boot, Node.js
  • Data: SQL/NoSQL systems
• Integrate AI services into existing enterprise systems and APIs.

• Use AI tools (Claude, Copilot, etc.) for:
  • Code generation and refactoring
  • Debugging and optimization
  • Test generation and documentation
• Continuously evaluate and adopt new AI tools to improve engineering velocity.

• Build and maintain CI/CD pipelines (Azure DevOps) for AI applications.
• Optimize system performance, scalability, and reliability of AI workloads.
• Monitor and improve model performance, latency, and cost efficiency.

• Bachelor’s degree in Computer Science, IT, or related field + relevant experience.
• Strong experience with:
  • Python (FastAPI preferred)
  • Modern backend or full-stack frameworks
• Hands-on experience with:
  • RAG architecture, embeddings, and vector databases
  • LLMs (GPT, Claude, or similar)
• Experience deploying applications on Azure (AKS, Azure AI services).
• Familiarity with Docker, Kubernetes, and cloud-native architectures.
• Experience with MS SQL, Azure storage, Azure App services, APIM.

• Experience with Azure AI Foundry or similar GenAI platforms.
• Strong understanding of:
  • Prompt engineering
  • Context management in LLMs
  • Fine-tuning / evaluation techniques
• Experience with vector DBs like Qdrant, Pinecone, or Azure Cognitive Search.
• Exposure to agent frameworks (LangChain, Semantic Kernel, AutoGen, etc.).
• Prior experience building AI copilots or internal AI tools.
