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.
