About The Position

Trainual is looking for a Full Stack AI Product Designer— otherwise known as a “Product Design Engineer”. A designer-first role for someone who pairs exceptional product design craft with a strong understanding of modern AI workflows and frontend development. You’ll design high-quality user experiences, contribute to product squads, and help evolve how design and engineering work together in an AI-augmented development environment. While design excellence is the core of this role, you’ll also bring enough frontend and technical fluency to help bridge the gap between design and engineering. You’ll partner closely with other designers, engineers, and product managers to ship thoughtful, polished experiences while helping ensure our design system and workflows work seamlessly in an AI-driven product development world. You’re a designer at heart with exceptional UX and visual craft who is energized by the intersection of design, engineering, and AI. You love designing intuitive experiences, but you’re also curious about how things are built and how emerging tools can make teams faster and more creative. You thrive working inside product squads while also helping elevate the broader design team.

5+ years designing SaaS products
Exceptional UX and UI craft — you care about the details and visual polish

Want to help ensure design systems and product interfaces are ready for AI-assisted and agentic development environments
