Senior Full-Stack Software Engineer - AI/LLM

About the role

The client is seeking a Senior Full-Stack Software Engineer to join the GenAI Discovery and Prototyping team. This individual will help deliver a major platform upgrade that connects enterprise data pipelines, large language models (LLMs), and rapid application prototypes. This is a true full-stack delivery role. The engineer will build scalable application layers using C# on the back end and React with TypeScript on the front end. A core focus of the position will be designing reliable software solutions that securely ingest, validate, process, and return LLM outputs within an enterprise ecosystem. The ideal candidate has a strong engineering foundation, understands LLMs as statistical tools, and has direct, hands-on experience building applications powered by generative AI. Because this team operates in a fast-paced prototyping environment inside a mature enterprise, the engineer must be comfortable navigating secure data environments, collaborating across multiple staging environments, and adapting quickly as platform requirements evolve.
