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.
