Mobile Principle Software Engineer

Role overview A principal-level mobile engineer will lead a mobile team through a shift toward AI-centered product development. The role combines hands-on iOS and Android work, mobile and participant platform architecture, and engineering leadership, with some contribution to a Python backend. It calls for close partnership with Product and Design to shape user problems, choose when to prototype, and build durable foundations where needed.

Responsibilities - Guide the mobile team’s technical direction, delivery, and continued growth. - Establish development workflows using AI coding agents, including evaluation and review practices. - Shape a thin-client architecture that keeps mobile apps focused while placing shared business logic in backend services. - Contribute Python backend capabilities when required by mobile product needs. - Set direction for participant APIs and the broader participant platform. - Improve delivery processes, operational practices, and continuous delivery across partner teams. - Mentor engineers and contribute to security and compliance work.

Requirements - Principal or Staff-level impact as a product-focused software engineer, with 10+ years of experience evolving or launching applications. - Significant hands-on experience with both iOS and Android development. - Practical experience using AI coding agents to deliver production work, with sound judgment about their use. - Ability to work beyond mobile when needed, including contributing to Python services. - Experience leading technical improvements, mentoring engineers, and setting direction with limited oversight. - Strong product judgment and ability to work as a peer with Product and Design.
