You're not just a technical leader - you're someone who believes that the best software feels invisible, that elegant architecture enables beautiful experiences, and that the most powerful feature is often the one you don't have to think about. You've built systems that scale, but more importantly, you've built systems that matter . You understand that when we're processing 100,000 newsletters daily, we're not just moving data - we're preserving thousands of hours of human creativity and enabling millions of moments of discovery and reflection. 🌿 A Final Thought "Reading deserves a sanctuary. We're not here to fight for attention. We're here to protect it." We're building Inbo.club for everyone who has ever saved a newsletter to read later, only to lose it in the noise. For everyone who believes that the best technology is the kind you don't have to think about. For everyone who thinks the internet could be a little more thoughtful, a little more human. If you're someone who wants to build technology that serves human flourishing rather than exploiting human attention, we should talk.

Our React Native app is live with real users, and we're building v2 with AI recommendations. You won’t just design screens. You’ll shape how people feel when they open Inbo — from the first impression to the reading rituals they form every day. We’re looking for someone to co-design the product, not just the pixels. Someone who will think: “How should reading feel on a phone?” “How do we balance content density with calm design?” “How does AI show up gently, without stealing focus?” “What’s a streak or highlight system that motivates, not overwhelms?” You’ll be designing mobile-first, yes, but also reader-first. What You’ll Work On Mobile-first UI/UX : Design core screens like Inbox, Reader, Highlights, and Discovery Microinteractions : Create small moments of delight — from streaks to swipes AI Features : Visualize summaries, reading insights, and smart actions Dark Mode & Typography : Craft a cozy, long-form reading experience Touch-first UX : Swipe gestures, bottom navigation, one-handed reading Onboarding & First Use : Help users fall in love from the first tap User Analytics & Feedback Loops : Design ways to show and collect insights ✅ What We’re Looking For Portfolio that includes mobile app design (especially reading or productivity apps) A designer who’s shipped at least one mobile app or MVP Strong visual and UX skills (Figma is your sketchpad) Systems thinking — you design flows, not just screens Sensitivity to content-driven design (you care about whitespace, legibility, and flow) Self-driven, proactive, and open to feedback Bonus: experience designing reading tools, productivity apps, or slow-tech products What You'll Design The core mobile app: inbox → reader → discovery → highlights AI summaries, reading insights, and intelligent prompts Onboarding, streak flows, pro experiences Highlight tools, note systems, save/share flows Visual themes (dark/light), font size control, mobile typographic system Subscription management, gesture-based UX, mobile-only interactions First-use flows, empty states, and thoughtful nudges Upcoming Design Challenges You’ll Face Designing touch-friendly, readable layouts for long-form content Making AI tools feel helpful but invisible Creating delightful streaks and progress features without addiction loops Helping users organize and revisit what they read Handling edge cases like Gmail imports, failed loads, or empty inbox days Designing for a productivity user , but in a playful, calm environment We believe design isn’t just about how something looks — it’s about how it feels, how it flows, and what it invites people to do with their time. If you’re the kind of designer who thinks about the in-between moments — the scroll, the pause, the subtle animation, the way content breathes — we’d love to build this with you. Let’s create something slow, useful, and beautiful.
