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)
• 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

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.

• 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

What They’re Looking For

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

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