The New Architecture
Fabric, TurboModules and JSI — and the work of upgrading the libraries that haven't caught up yet.
Senior / Staff
Mobile engineers who ship iOS and Android apps from one TypeScript codebase — with native modules where the platform demands them, and release pipelines that don't depend on one person's laptop.
Role profile
Seniority and experience are agreed in the proposal, and you interview every engineer before they start. These are the skills that interview should test.

FAQ
Answered the way we would on a call. If yours isn’t here, send it — we reply within one business day.
For most product apps, yes. The New Architecture removed the old asynchronous bridge, and animations can run on the UI thread. For heavy graphics or deep platform features, we write native modules — or recommend going native for that part.
Expo EAS Update ships JavaScript and asset changes directly to installed apps. Changes to native code still go through App Store and Google Play review, and the stores' rules on what an update may change still apply.
