Principal Product Designer — UX/UI

Job Responsibilities:

You will be the lead designer on a small, senior Growth pod — you, an engineer, and a data analyst — reporting directly to the Chief Growth Officer. The pod's job is to ship experiments and UX improvements at high velocity across both the parent-facing app and the child-facing experience.

This is not a features role, and it is not measured in mockups shipped. You will be held accountable to one KPI: retention across our [REDACTED] Phone, [REDACTED] Watch, and [REDACTED] App install base.

• Own retention as a design problem. Diagnose where subscribers lose momentum, disengage, or churn across the [REDACTED] Phone, [REDACTED] Watch, and [REDACTED] App, and design the changes that keep them getting value.
• Lead the ground-up redesign of [REDACTED]'s app experience . Incremental testing alone won't fix a product that customers find unintuitive. You'll own a larger overhaul of the parent and child app UI — setting a clear, opinionated point of view on what "intuitive" looks like for [REDACTED], sequencing the work into shippable phases, and organizing the pod to deliver it without stalling the experiment engine. This demands strong taste, sound judgment about what to change and what to leave alone, and the ability to turn a big vision into an execution plan others can rally behind.
• Run a high-velocity experiment engine with your engineer and analyst — framing hypotheses ("if we do X, retention metric Y improves by Z"), designing the variants, and shipping A/B and multivariate tests continuously. Most experiments won't win; the point is to learn fast and compound the wins.
• Design for two very different users. The parent-facing app (setup, alerts, controls, insight) and the child-facing experience have different needs, literacy levels, and constraints. You'll design for both.
