Role description
Nous ResearchSoftware 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.
