Principal Product Designer
About the role
Stardust is a design-led reproductive health app used by over 2 million monthly active users. We blend scientific insights with wonder and ancient wisdom — offering lunar cycle syncing, friend syncing, a best-in-class pregnancy experience, and a partner option. Our engineering team of 7 spans iOS, Android, backend, and web. We are a seed-stage company building with the ambition and complexity of a much larger organization.
Roles & Responsibilities
Shape the Core Product Experience
Millions of people open Stardust every day to understand what's happening in their body. You decide what that experience looks and feels like.
Lead design across all core features: cycle and temperature tracking, predictions, sleep, mood logging, pregnancy mode, and partner view
Turn complex health data into interfaces that feel like art, never clinical. Set the bar for how health information should look and feel
Write your own briefs, own the spec, and hand off clean enough to ship right
Track what ships, review what works, report back. Define and Evolve the Design System
The design system is the foundation everything else is built on
Own the Stardust design system end-to-end and evolve it as the product grows
Maintain consistency and quality across iOS, Android, and web while respecting what makes each platform different
Write contribution guidelines so engineers can build inside the system without you
Drive Growth through Design
Great design isn't just how it looks. It's how it converts, retains, and brings people back
Work with growth team to design A/B experiments on high-leverage funnel steps with a bias toward learning fast
Build a modular component library so experiments don't require full redesigns
Use data to find drop-off, form hypotheses, iterate
What We're Looking For
Comfortable designing for both iOS and Android native apps as well as web. You understand the nuances of each platform and know when the rules differ
6+ years of product design experience, including significant time as the lead or sole designer on a consumer mobile app
Exceptional visual craft. You make interfaces that feel alive, not just usable. Your work doesn't look like anyone else's
You run your own process — you don't need a PM to write your brief or a manager to set your priorities
Figma fluency. You've built and maintained design systems, not just used them
A portfolio showing real range: systems thinking, complex health or data UI, growth surfaces, and rich visual design
You know how to ship specs and prototypes. You know when to use what, and you follow through to production
Strong point of view on what makes a product feel distinctive and you push back when something is generic
Experience in health, wellness, femtech, or consumer subscription apps
Bonus: Familiarity with motion and interaction design
