We build modern web & mobile apps for global clients using React, React Native, Next.js, and TypeScript - and we’re looking for more Makers to join us. If you’re the kind of person who takes pride in clean, maintainable code and enjoys having real ownership over what you ship, you’ll fit right in. 🌳 🧩 What you’ll do Build and maintain mobile applications (the current case is strictly native iOS, but React Native will be a plus in the long term). You are comfortable doing native development with Swift. Collaborate directly with clients and teammates - from feature discussions to deployment. Review PRs, give feedback, and help keep our codebase elegant and reliable. Contribute ideas: we value people who think beyond the ticket. 🧠 What we value Solid experience (4+ years) with native iOS development , and relevant modern tooling/libs. Comfort working independently and asynchronously in a remote setup. Consistently reporting on progress via PRs, demos via recorded screenshare videos and up-to-date project boards. Ability to use AI/LLMs as a force multiplier in delivering your work. Optional, but welcome: interest to work with React Native in the future. Curiosity, humility, and kindness. We like people who make the team better. 🚀 Why Makers’ Den 100% remote - no offices, no micromanagement. Founders are active senior devs - we code, review, and mentor (when we have time 😅). Annual in-person meet-up (company-paid travel, hotel, and dinners). A culture of autonomy, craft, and learning - no unnecessary managerial layers. 🔍 The process Short intro call. Small take-home coding challenge (reasonable and realistic). 90-minute conversation - we’ll discuss your work and ours. Offer, if we’re a match. 👉 Learn more about us in our Maker Handbook 📕 . We look forward to hearing from you!
