Senior UX Interface Designer with Security Clearance

We are seeking a Senior UX Interface Designer with a genuine, discerning visual sensibility who can recognize the difference between a screen that merely functions and one that commands attention, builds trust, and makes an athlete want to keep coming back. This is not a role for someone who executes a design system without aesthetic judgment. We need a designer who has a point of view, can defend it, and can elevate our product visually while remaining disciplined within our design constraints.

This role owns the Presentation Layer - how the product is formatted in terms of fonts, graphics, and animation, along with intuitive navigation. Key focus areas include innate visual design sensibility applied to a premium dark-surface consumer product; identity-driven, personalized experiences that adapt to each user's performance profile; high-quality motion and interaction design that communicates performance and progress; and action-oriented workflows that eliminate passive data consumption.

This is a startup environment where the ideal candidate thrives building from 0-1, is comfortable with ambiguity, and takes ownership rather than waiting for direction. We move fast, hold a high visual standard, and ship against hard dates. We also leverage modern AI-assisted development tools to accelerate delivery; comfort in these environments is a must. Key Tasks & Responsibilities Visual Design Leadership (Defining Responsibility)
* Own the overall aesthetic standard of the product: typography application, spatial rhythm, depth hierarchy, color restraint, icon quality, and component polish
* Ensure the product reads as a premium consumer tool - not a clinical health app, generic fitness tracker, or scaled-up spreadsheet
* Apply visual judgment to commercial surfaces (marketplace, subscription tiers, upsell moments) while maintaining trust in the system
* Build and maintain the authoritative Figma (or equivalent) design system: token library (colors, type ramps, spacing, radius, motion), component library, and identity cell documentation Identity-Driven & Personalized Experience Design
* Design the identity recoloring moment in onboarding as the signature emotional beat of the product - a real-time ambient palette transition that feels intentional, earned, and beautiful
* Ensure the primary dashboard identity symbols function coherently as both the user's visual identity expression and the entry point to the AI coaching layer
* Design the shareable identity card in both quiet (clean, restrained) and expressive (gamified, bold numbers) aesthetic modes
* Ensure scoring loops, streak mechanics, and progression tier displays feel motivating and identity-consistent - not a generic gamification model Motion Design & Interaction (Critical)
* Design and spec all animated moments, including the readiness score arc animation, the pre-launch cinematic welcome experience, identity ambient recolor, mission/achievement completion states, AI coaching insight reveals, and score/pillar change reveals
* Define motion standards for the full product: screen transitions, micro-interactions, press states, loading states, skeleton screens, empty states, and error states
* Produce implementation-ready motion specs for multiple devices:
Bodymovin/Lottie files, timing curves, duration values, and engineering handoff notes UX/UI Design Across the Full Screen Inventory
* Design action-oriented experiences that tell the user what to do next; every screen should have a clear direction rather than a passive display of data
* Translate complex biomarker, wearable, and AI-generated data into interfaces that are immediately readable and emotionally resonant - not dense, clinical, or overwhelming
* Design the dashboard priority engine as the product's daily engagement surface - one that feels like a coach, not a notification list
* Design an AI coaching modal as a distinct experience layer, and maintain high-fidelity designs across iOS, Android, and Web simultaneously (design once, build anywhere) Cross-Platform Consistency & Engineering Collaboration Ensure a unified visual and interaction experience across iOS, Android, and Web - respecting platform-specific behaviors without fracturing the design system Education & Experience
* 5+ years of experience in UX/UI and product design, with at least 2 years designing for mobile (iOS/Android) at a consumer product company Must Demonstrate
* Understanding of color as a functional system communicating status, identity, causality, and trust
* Proficiency in Figma or equivalent - component libraries, auto-layout, design tokens, prototyping, and developer handoff
* Proficiency in motion/animation tools (Lottie, After Effects, Framer, or equivalent) with demonstrated ability to spec animations for engineering implementation
* Comfort with AI-assisted development tools such as Lovable, Cursor, or similar, and willingness to adopt new tooling quickly

Preferred Qualifications
* Experience designing for health,…
