Job Description

We are looking for a visionary Senior UX/UI Designer to take the helm of our design strategy and execution. Mobile messaging is at the heart of how people connect, and in this role, you won’t just be "working on an app" - you will own the end-to-end design experience across our entire mobile app.

You will drive the Vision and own product design across our platform.

You will lead UI and UX from discovery through delivery.

You will be the architect of our Figma design system, maintaining its integrity while evolving it to meet new product challenges.

Reporting directly to Product and partnering intimately with Engineering, you’ll bridge the gap between "what's possible" and "what's beautiful."
