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.
