About the role
- Develop AI‑powered applications using state‑of‑the‑art LLMs
- Build and deploy applications for internal customers, selecting the right models (e.g., GPT‑4o, Claude Sonnet 4, Gemini 2.5 or open‑source alternatives)
- Implement retrieval‑augmented generation (RAG) pipelines and agents using LangChain, LangGraph, LlamaIndex, and other emerging frameworks
- Integrate ML models with front-end apps, REST APIs, and backend systems
- Design and build end-to-end AI systems—ranging from chatbots and recommendation engines to vision-based pipelines
- Build robust logic around ML models to address edge cases, failovers, and complex business rules
- Leverage prebuilt models or services (e.g., OpenAI API, Azure Cognitive Services, HuggingFace) to accelerate development cycles
- Fine‑tune and customize models using LoRA, prompt tuning, or RLHF techniques
- Occasionally perform custom model training—but more often fine-tune or adapt existing models to meet business needs
- Work with vector databases (e.g., Pinecone, Weaviate) and explore graph-based approaches (e.g., GraphRAG, Knowledge Graphs)
- Ensure privacy and compliance with HIPAA, including encryption, PHI protection, and vendor due diligence
- Prototype multi‑agent systems using frameworks like CrewAI or Stands SDK and evaluate emerging agent orchestration solutions
- Collaborate cross-functionally with product managers, data scientists, and compliance teams
- Mentor junior engineers, lead innovation discussions, and continuously evaluate emerging LLM architectures
