You've made real decisions, not just about implementation, but about what the right product and technical approach was. An eye for detail. Strong opinions about how things should work. The kind of person who thinks about how something fits into the bigger picture, not just whether the code works. Drawn to work that compounds. Curious how great products work. ## Description You'll ship across web (React, Next.js), desktop (Electron, Swift), mobile (React Native), and backend. You'll work on AI-powered outcomes, search, transcription, on-device recording, performance, and automations. You'll experiment with new AI models and techniques. And you'll raise the bar for the team through code review and building reusable tools. We're a small team that moves fast. You'll ship real features to thousands of paying customers every week, not sit in planning meetings. ## Related Videos - [But, you're not Facebook](https://www.wearedevelopers.com/videos/378-but-you-re-not-facebook) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Next, Nest, Nuxt… Nust?](https://www.wearedevelopers.com/videos/421-next-nest-nuxt-nust) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [16 Best Free React UI Libraries in 2025](https://www.wearedevelopers.com/magazine/148-16-best-free-react-ui-libraries-in-2025) - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding)
