Our client is building an AI App Builder — a platform that allows anyone to create functional applications through natural interaction with AI. Users describe their ideas — and the system builds the app.
Their small, high-impact team is shaping the foundation of the product: architecture, interface, and AI integration layer. They’re looking for an experienced engineer with strong leadership skills, technical vision, and hands-on experience in AI-related projects, someone who can see the full picture — from code to product — and drive the team toward clean, scalable solutions
