AI Engineer, Python FastAPI & LLM Systems
Overview
Own the design and deployment of an AI-powered support bot for Hypercare query resolution, processing thousands of enterprise queries daily. You will build RAG pipelines, Agentic AI Workflows, and integrate Large Language Models into production. Work with Python and FastAPI in an onsite Sunnyvale, CA team. This role stands out for its focus on agentic systems and knowledge assist, requiring deep technical ownership from day one.
What You'll Do8
- 1Build the core RAG pipeline using Python and FastAPI to retrieve and synthesize answers from enterprise knowledge bases.
- 2Design Agentic AI Workflows that break down complex queries into sub-tasks, coordinate tool calls, and produce reliable resolutions.
- 3Ship LLM-based features such as prompt chaining, context windowing, and model routing to optimize response accuracy and latency.
- 4Integrate the support bot with internal data sources and APIs to enable real-time Hypercare query handling.
- 5Debug and tune LLM performance, managing token budgets and logging traces to minimize hallucination.
- 6Drive testing and evaluation of retrieval quality, using RAG metrics to refine chunking and embedding strategies.
- 7Scale the FastAPI service to handle high concurrency, implementing caching and async patterns.
- 8Collaborate with product and data teams to define knowledge schemas and ingestion workflows for the assistant.
Requirements8
- 15+ years building AI applications with Python and FastAPI in production environments.
- 23+ years hands-on with LLM frameworks like LangChain, LlamaIndex, or Haystack for RAG systems.
- 32+ years designing Agentic AI Workflows, including tool orchestration and autonomous decision-making.
- 4Experience integrating enterprise knowledge bases (e.g., Elasticsearch, Pinecone, Weaviate) with vector search.
- 5Proven track record shipping end-to-end AI products from prototype to production, including monitoring and observability.
- 6Strong understanding of prompt engineering, fine-tuning, and model evaluation for support chatbots.
- 7Bachelors or Masters in CS or related field, with a focus on AI/ML.
- 8Onsite availability in Sunnyvale, CA for the length of the contract.
