Software Engineer, Mobile
Join the Product team building Hermes Agent on mobile. This role owns the phone experience end to end: the native iOS and Android apps, the shared cross-platform layer behind them, and the backend work that makes the agent feel fast and reliable in your pocket.
Responsibilities:
-
Build and own the Hermes Agent mobile apps on iOS and Android, from UI down to the APIs that feed them.
-
Ship native-quality experiences: smooth interaction, offline resilience, push notifications, and responsible battery and data use.
-
Work across the mobile stack, from Swift/Kotlin where it counts to a cross-platform layer (React Native or similar) where it speeds us up, and help decide where each fits.
-
Partner closely with Product and Design to turn ideas into polished mobile features, then iterate on real usage data.
-
Handle the app-store realities: release pipelines, review processes, versioning, and staged rollouts.
-
Keep the mobile experience consistent with desktop and web without flattening what makes each platform good.
-
Build automated testing that keeps releases reliable across devices and OS versions.
-
Work with Research and AI teams to bring new model capabilities into the mobile app.
Qualifications:
-
5+ years of software engineering experience with a strong focus on mobile.
-
Shipped and maintained production iOS and/or Android apps that real people use.
-
Strong with native mobile development (Swift, Kotlin, or both) and comfortable with a cross-platform framework like React Native.
-
Solid backend and API sense: you can build the endpoints your app needs, not just consume them. TypeScript/Node.js or Python experience is a plus.
-
Real product intuition and a high bar for how a mobile app should look and feel.
-
Comfortable owning features end to end in a fast-moving environment.
Preferred:
-
Experience with app-store submission, review, and release management on both platforms.
-
Familiarity with offline-first architecture, local storage, and sync.
-
Interest in AI agents and open-source software; bonus if you've used Hermes Agent yourself.
-
Experience integrating with LLM or streaming APIs on mobile.
