Senior UX Interface Designer

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, fitness, performance, or biomarker applications

Experience designing consumer commerce surfaces in a trust-sensitive context, including in-app purchases, subscription tier presentations, or health/telehealth marketplaces

Familiarity with React Native / Expo design constraints: safe areas, platform-specific scroll physics, gesture models, and native component behavior

Light front-end knowledge (TypeScript, React Native, CSS) sufficient to assess implementation fidelity and communicate specific divergence from design intent

Experience designing gamification and progression systems: achievement states, streak mechanics, leaderboard displays, tier progression

Familiarity with identity-adaptive or multi-theme design systems: real-time palette shifts, persona-keyed visual treatments, multi-tier token management

Experience with cinematic or motion-heavy product moments (brand launch surfaces, product reveal animations, celebration states) and demonstrated ability to art-direct sound, motion, and timing together

Certifications

Applicable certifications are a plus

Other (Travel, Work Environment, DoD 8570 Requirements, Administrative Notes, etc.)

Fast-paced, milestone-driven startup environment with hard ship dates; role leverages AI-assisted development tools (Cursor, Lovable, and equivalents) to accelerate design and development velocity
