Mobile Principle Software Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Mobile Principal Software Engineer based in the United States. The Mobile Principal Software Engineer will lead the evolution of a mobile engineering team as it transitions toward an AI-first product platform. This hands-on technical leadership role combines mobile architecture, AI-assisted development, backend collaboration, and product strategy. You will help reshape the participant experience across iOS, Android, and web while building development practices that enable teams to deliver high-quality software at unprecedented speed. Working closely with Product, Design, and engineering partners, you will balance rapid experimentation with scalable, maintainable architecture. You will mentor engineers, improve delivery processes, and influence the direction of the broader participant platform. This is a remote-first opportunity for a product-minded technical leader who thrives in a fast-moving, collaborative environment. Accountabilities - Lead the mobile engineering team, guiding its technical maturity, architecture, and evolution to support an AI-native product platform. - Establish an AI-native software development lifecycle for mobile engineering, incorporating AI coding agents, evaluation frameworks, review loops, and quality controls to sustain rapid delivery. - Drive a thin-client architecture for the participant experience, moving business logic toward backend services to keep mobile applications streamlined and maintainable. - Contribute to Python-based AI backend services when new capabilities are required by mobile, using AI coding agents to accelerate implementation. - Define the direction of participant APIs and the broader participant platform, influencing technical decisions beyond the mobile team.

- Allocate approximately 70% of time to supporting the product team and 30% to self-directed technical leadership, platform improvements, and strategic initiatives. - Improve engineering processes across the mobile team and partner teams, identifying opportunities to increase efficiency, quality, and collaboration. - Apply DevOps principles to strengthen continuous delivery pipelines and improve the reliability and operational performance of SaaS and mobile systems. - Mentor engineers, support their professional growth, and contribute to the continued development of the wider Engineering organization. - Participate in organizational security and compliance initiatives, supporting a platform operating within SOC 2 and HITRUST certification requirements. - Collaborate with Product and Design as a strategic partner, helping define problems, evaluate trade-offs, test assumptions through prototypes, and build durable technical foundations where appropriate. - Manage multiple initiatives simultaneously, identifying dependencies, potential conflicts, and opportunities for shared solutions while maintaining alignment with business priorities. Requirements: - More than 10 years of software engineering experience, with substantial mobile development expertise and Principal- or Staff-level technical leadership scope. Demonstrated impact and delivery are more important than job titles. - Experience developing for both iOS and Android, with the flexibility to work beyond the mobile ecosystem when business or technical needs require it. - Hands-on experience using AI coding agents such as Claude Code, Cursor, Codex, or similar tools to deliver meaningful production work, along with a clear perspective on designing an effective software development lifecycle around AI agents. - Strong systems architecture experience spanning backend API design, databases, mobile DevOps, and the trade-offs involved in designing connected product systems. - A proven track record of leading technical improvements, mentoring engineers, and helping engineering teams grow.
