Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Software Engineer, Mobile - **Company:** Custral, LLC - **Location:** New York, NY, United States - **Salary:** $130,000.0 - $170,000.0 - **Contract:** Permanent contract - **Skills:** Application Programming Interfaces (APIs), Artificial Intelligence, Software Applications, Mobile Application Software, PostgreSQL, Node.Js, Web Applications, React Native - **Published:** September 24, 2026 - **Apply:** https://www.thejobnetwork.com/job/software-engineer-mobile-509975523 ## About the Role * You're deeply fluent in TypeScript and strong in React Native, ideally with Expo * You've shipped and maintained an app in both app stores, including the review and release parts nobody enjoys * You've handled offline state, sync and conflict resolution in a real product * You're comfortable enough on the backend to build the endpoints your screens need, in Node and Express against Postgres * You have taste about what belongs on a phone and can defend cutting things * You do your own research and move work forward without waiting for direction Useful, not required: native modules and the bridge; push and deep linking at scale; Electron; building with AI coding tools, which is how we work. Don't apply if you only want to build screens against someone else's API. There isn't someone else. Strong candidates ship real functionality without cutting corners, explain their tradeoffs, and leave the system better than they found it. ## Description Most CRMs stop at the closed deal. Everything after it, implementation, support, renewal, product feedback, ends up spread across five tools that don't share a record. Teams bend their process to fit the software and keep the real work in spreadsheets. Custral is one workspace for the whole loop. Marketing, sales, onboarding, success and product work from the same customer records. You shape the objects, views and workflows around how you run, instead of the other way around. AI agents live in the data model rather than on top of it, with real scoping, tool gating and model selection across OpenAI and Anthropic. Stella, our assistant, works the same records the rest of the product does, and asks before she sends anything. It is early. We're letting teams in a few at a time. The role Own Custral on the phone. The mobile app is Expo and React Native, built out of the same monorepo as the web app and the Electron desktop app, sharing types, SDK and UI packages with both. That sharing is the interesting constraint: the phone is not a shrunken CRM, and deciding what belongs there and what doesn't is most of the job. You'd own it end to end. Product decisions, the React Native work, the Node and Express endpoints behind it, offline and sync behavior, push, and the release train through both app stores. Nobody is going to hand you a spec for the phone, because nobody else is working on it. ## Related Videos - [There's an app for that - on the role of cross platform development in the app development ecosystem](https://www.wearedevelopers.com/videos/278-there-s-an-app-for-that-on-the-role-of-cross-platform-development-in-the-app-development-ecosystem) - [Challenges of building React and React Native apps](https://www.wearedevelopers.com/videos/448-challenges-of-building-react-and-react-native-apps) - [Stop using Node.js like in 2020!
