We are looking for a Lead Python AI Engineer to build robust, AI-powered API services and agentic workflows. In this role, you will bridge the gap between traditional backend systems and modern language models, focusing on secure and scalable LLM interactions with internal systems, vector databases, and external tools via orchestration frameworks.

Responsibilities

End-to-End Ownership
Own API contracts and service reliability end-to-end. AI edge cases must fail gracefully without compromising system integrity
Rigorous Systems Engineering: Integrate LLMs with a strong engineering foundation—baking in evaluation, comprehensive observability, robust fallback handling, and cost awareness
Reusable Frameworks
Build reliable, reusable orchestration frameworks and logic designed for downstream developer consumption
Design and build scalable backend API services and advanced LLM orchestration layers
Implement and maintain complex RAG (Retrieval-Augmented Generation) pipelines, covering document ingestion, chunking, embedding, and retrieval optimization
Develop and connect agent tools using LangChain, LangGraph, and potentially MCP (Model Context Protocol)
Ensure top-tier security, privacy, enterprise-grade observability, and comprehensive test coverage across all backend workflows
Contribute actively to architecture decisions and engineering standards within your pod
