As a Senior AI Engineer at United Airlines, you will be a key member of the Digital Technology team involved in the Mosaic Program, which aims to modernize the Passenger Service System (PSS) through a cloud-based platform. Your role will involve transforming legacy applications into cloud-based ones, as well as designing, developing, and deploying advanced LLM-powered applications to enhance the overall Software Development Life Cycle (SDLC) process. You will play a crucial role in driving efficiency and accelerating the transition to a modern, cloud-native PSS ecosystem. **Key Responsibilities:**
**SDLC Acceleration:** Engineer AI agents and workflows to automate the reverse engineering of legacy codebases and expedite the migration to cloud-native microservice architectures. - **AI Orchestration:** Design and develop stateful, multi-agent reasoning systems using LangGraph to handle complex logic transformation and code generation. - **Hybrid Development:** Maintain proficiency in writing high-quality .NET/C# code for core PSS services while building Python-based AI tools to support them. - **RAG Implementation:** Build Retrieval-Augmented Generation (RAG) pipelines to index and query vast technical documentation and legacy specifications. - **Model Integration:** Deploy and optimize LLMs (OpenAI, Claude, LLaMA, AWS Bedrock) to automate testing, documentation, and code generation/refactoring. - **Observability:** Implement LangSmith to evaluate agent performance, ensuring that AI-generated outputs meet United's standards for safety and reliability. **Qualifications:**
**Minimum Qualifications:**
5+ years of experience as a manager or Technical lead
10+ years in Programming with dual proficiency in Python (for AI) and .NET/C# (for application development)
