About the role

Our partner is looking for a Staff Mobile Engineer, Tech Lead based in the United States. This is a senior individual contributor role responsible for shaping the long-term technical direction of a high-scale mobile platform serving more than one million users each week. You will lead architecture and engineering strategy across iOS and Android through React Native, with a strong focus on performance, reliability, and scalability. The role combines deep hands-on engineering with cross-functional technical leadership across Engineering, Product, Design, Data, and business teams. You will help advance AI adoption in mobile development, including agentic coding tools, on-device intelligence, and AI-powered product experiences. You will establish engineering standards around architecture, testing, observability, CI/CD, release quality, and mobile development practices. As a technical leader, you will mentor engineers, influence organization-wide decisions, and lead complex initiatives that span multiple teams. The environment values ownership, experimentation, operational excellence, collaboration, and continuous improvement while giving engineers significant influence over the evolution of the platform.

Responsibilities

• Define and drive the long-term technical vision, architecture, and infrastructure strategy for the mobile platform across iOS and Android using React Native.
