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.

5+ years of software engineering experience focused on mobile; production iOS or Android app experience; Swift or Kotlin; React Native; backend and API development; end-to-end product ownership.
