Principal Product Designer, Mobile

Otto is building a personal AI assistant that runs on a dedicated device and connects to the apps people use every day. Our mobile and desktop apps let people talk to Otto, connect their accounts, and control the actions their assistant takes. We’re looking for a Principal Product Designer to own the mobile experience—from setting up a device for the first time to making Otto part of someone’s daily routine.

Lead end-to-end mobile product design, from research and early concepts through prototypes, implementation, and iteration.

• Design clear experiences for device setup, AI conversations, connected apps, permissions, and approvals.
• Establish interaction patterns that work across mobile and desktop while respecting platform conventions.
• Build and evolve our design system, including components, typography, motion, and accessibility.
• Work closely with engineers to ensure the shipped experience meets the design intent.
• Set a high standard for design craft and help the team make thoughtful product tradeoffs. A portfolio of shipped consumer mobile products showing strong product thinking, interaction design, and visual craft.
• Experience leading complex design work at a principal, staff, lead, or equivalent level.
• Deep understanding of iOS and Android conventions and accessible mobile design.
• Connected devices, device onboarding, or software that spans hardware and mobile.
• Designing for React Native applications.
• Building consumer products in an early-stage team. You’ll shape how people interact with a personal AI assistant across software and hardware. Share your résumé or LinkedIn profile and your portfolio. Include one mobile product you’re proud of, explaining what you owned, what shipped, and what you learned.
