Are you an experienced software engineer who has moved into the AI space?

I'm working with a VC-backed SaaS company helping product and engineering teams build, document, and scale design systems used across global organisations.

They're now investing heavily in AI and are looking for a Senior AI Engineer to help build the foundations of an agentic platform that connects documentation, design systems, codebases, and AI-powered workflows.
