About our client

Purpose is creating the world's first AI-powered personal growth coach—helping people move from "I'm doing fine" to "I know who I am, what I care about, and how to live with clarity." They are building the visual language of personal transformation.

The foundation is proven:

• Co-founded by Mark Manson (20M+ readers, The Subtle Art of Not Giving a F***) and Raj Singh (100M+ users, last AI product acquired by Revinate)

The Role: Mobile Development with Polish and Purpose

This individual will be a key part of the mobile team building the React Native app that guides people through their personal growth journey. Purpose needs someone who cares deeply about creating smooth, polished mobile experiences—where every transition feels natural and every interaction delights users.

Mobile app development

• Build and enhance the React Native app with smooth animations and micro-interactions
• Implement the AI avatar system with engaging, personality-driven animations
• Create polished UI transitions: section expansions, modal presentations, gesture responses
• Develop visual feedback systems that celebrate user progress and breakthroughs

Core technical work

• Build robust real-time systems with streaming AI responses: WebSockets/SSE/GraphQL subscriptions handling queued/sending/streaming/complete/failed states
• Optimize performance for long conversation threads: virtualization, memory profiling, 60fps consistency
• Ship core user experiences: onboarding flows, conversation threads, search/export, weekly insights, privacy controls
• Integrate seamlessly with backend: auth, billing, analytics, push notifications with offline sync

React Native expertise:

• 4+ years shipping React Native apps with polished animations and smooth interactions
• Strong experience with React Native Reanimated for transitions, gestures, and micro-interactions
• Proven ability to maintain 60fps performance and optimize memory usage for mobile apps
• Portfolio showing attention to polish: smooth transitions, thoughtful loading states, delightful interactions

Mobile development foundation:

• Real-time systems experience: WebSockets, Server-Sent Events, or GraphQL subscriptions for streaming data
• TypeScript fluency with clean architecture patterns that scale
• Testing mindset: Jest, React Native Testing Library, Detox experience
• End-to-end ownership: App Store deployment, CI/CD pipelines, feature flags, rollout strategy

Mission alignment

• Excitement about using animation to create delightful, engaging experiences that keep people motivated on their personal growth journey
• Interest in how visual feedback affects behavior change and habit formation
• Belief that thoughtful design can create a welcoming environment for personal reflection and self-discovery

Bonus experience

• Expo EAS expertise and over-the-air update strategies
• Backend familiarity: Node.js, serverless patterns, API design
• Experience with character animations or avatar systems

Why This Opportunity Matters

• Creative impact: The mobile development work will be the first thing users see when they're exploring new insights, working toward goals, or celebrating progress. This isn’t just about building features—it’s about creating the digital experience that supports personal transformation.
• Technical growth: Opportunity to build the mobile architecture from the ground up as Purpose scales from hundreds to hundreds of thousands of users.
• Purpose-driven impact: This role shapes a product that genuinely improves people's lives—not optimizing ad revenue or engagement metrics, but building technology that helps people understand themselves and grow as individuals.
• Early-stage ownership: Direct input on technical decisions, architecture choices, and product direction as they build something meaningful from the ground up.
• Meaningful work: Every smooth interaction and thoughtful detail helps someone understand themselves better. This isn't just another productivity app.
