What We're Building
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." We're 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)
Launching in Q4 2025 to Mark's established audience
Seed-stage startup with runway to build something meaningful

The Role : Mobile Development with Polish and Purpose

You'll be a key part of our mobile team building the React Native app that guides people through their personal growth journey. We need 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 our React Native app with smooth animations and micro-interactions

Implement our 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

What You Bring

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 :

Advanced React Native animation libraries : Lottie for vector animations, complex gesture handling

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 :

Your mobile development work will be the first thing users see when they're exploring new insights, working toward goals, or celebrating progress. You're not just building features—you're creating the digital experience that supports personal transformation.

Technical growth :

Build our mobile architecture from the ground up as we scale from hundreds to hundreds of thousands of users.

Purpose-driven impact :

You'll help shape 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 we 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.

Salary :

$80k – $160k

0.5% – 1.0% equity

Purpose is an equal opportunity employer committed to creating an inclusive environment where everyone can bring their authentic selves to work. We encourage applications from candidates of all backgrounds who share our mission of making personal growth accessible through thoughtful technology.
