Software Engineer, Mobile

About the role

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Software Engineer, Mobile based in United States. This is an opportunity to own the mobile experience of an AI agent from end to end, across both iOS and Android.

Responsibilities

• Build, ship, and own production mobile applications across iOS and Android, from user interfaces through the APIs and services that power them.
• Deliver native-quality experiences with smooth interactions, offline resilience, push notifications, and responsible battery and data consumption.
• Work across the mobile stack using Swift and/or Kotlin where native capabilities are important, while leveraging React Native or a similar cross-platform framework where appropriate.
• Partner closely with Product and Design to translate ideas into polished mobile features and continuously improve them using real-world usage data.
• Manage mobile release operations, including app-store submissions, review processes, versioning, release pipelines, and staged rollouts.
• Maintain a consistent product experience across mobile, desktop, and web while preserving the strengths and conventions of each platform.
• Build and maintain automated testing to ensure reliable releases across devices, operating systems, and application versions.
• Contribute to backend APIs and services when needed to ensure mobile features have the reliable infrastructure and performance they require.

Requirements

• 5+ years of professional software engineering experience with a strong focus on mobile development.
• Proven experience shipping and maintaining production iOS and/or Android applications used by real customers.
• Strong proficiency in native mobile development with Swift, Kotlin, or both.
• Practical experience with a cross-platform framework such as React Native and the ability to determine when cross-platform versus native implementation is appropriate.
• Solid understanding of backend services and APIs, with the ability to build the endpoints and supporting functionality required by mobile applications rather than simply consuming existing APIs.
• Experience with TypeScript/Node.js or Python is a plus.
• Strong product intuition and a high standard for mobile usability, visual quality, responsiveness, and overall user experience.
• Able to own features end-to-end, make sound technical decisions, and operate effectively in a fast-moving environment.
• Strong collaboration and communication skills, with the ability to work closely with Product, Design, Research, and AI teams.
• Experience with app-store submission, review, and release management across iOS and Android is preferred.
• Familiarity with offline-first architecture, local storage, synchronization, and mobile reliability patterns is an advantage.
• Interest in AI agents and open-source software, with hands-on experience using AI products or agent technologies considered a plus.
• Experience integrating LLM or streaming APIs into mobile applications is an advantage.

Benefits

• Full-time remote opportunity for candidates based in U.S.
• Opportunity to own the mobile experience of an AI-powered agent across iOS and Android.
• Significant technical ownership across native mobile, cross-platform architecture, backend APIs, and release infrastructure.
• Closer collaboration with Product, Design, Research, and AI teams.
• Opportunity to work with emerging AI agent and LLM technologies and bring new model capabilities directly to mobile users.
• Fast-moving engineering environment with substantial influence over product and technical direction.
• Opportunity to build a product experience designed for real-world mobile usage, including offline reliability, performance, and efficient battery and data consumption.
