Onix is the Personal Intelligence platform. Each onix is a small language model trained exclusively on a single expert’s private corpus: clinical notes, unpublished research, proprietary methods that have never been on the internet and never will be. Onix lets you summon the actual judgment of a health and wellness expert who has spent a career on your problem, private and personal: names already live on the App Store include Dave Rabin, Mark Sisson, Ashley Koff, William Li, and Elissa Epel.

We need someone to own where the design of Onix goes next: apps, platforms, surfaces, flows, screens, UI/UX, and the design system underneath them. The ideal candidate has experience building consumer mobile products with heavy daily usage. We need someone used to environments where design decisions survive millions of live sessions, rather than just looking valuable in a portfolio.

You’ll be building this collaboratively, working in person with our team in Old Montreal. Product design. Design system.

Own the foundation: color, type, spacing, and components, so engineering, product,



and marketing can build from it directly. Ship with engineering. Sit next to the people building your work, specify clearly, review builds, and hold the line on the details that matter.

Present and defend design decisions to the founders regularly, work with the feedback, and come back with something better. Shipped consumer mobile products with real usage behind it, and you can walk us through the decisions, not just the screens. Built or substantially owned a design system, including the rules and the documentation behind it.

Prefer to stay hands-on and ship the work yourself. You want a remote job. You want to build and manage a design team rather than do the work yourself. You have shipped meaningful changes to the app, not just explorations.

Our design system has written usage rules, and everyone builds from it independently. Design decisions land with you directly. Design reviews with the founders move from fixing problems to shaping what comes next.
