Impact

As a Senior Principal Engineer on the Member Marketplace(Frontend Engineering) team, you will own the technical vision and platform architecture for Shipt’s Member Marketplace across both web and mobile app. You’ll lead the design, implementation, and evolution of core frontend systems—including component libraries, cross-platform UI foundations, and design systems—that empower multiple teams to deliver feature-rich, high-performance experiences. With a focus on modern React and React Native application architecture, you will guide best practices in Next.js (SSR/SSG), app development patterns, state management, routing, async data handling, lazy loading, and achieving world-class responsiveness on every device.
You will be a principal voice in platform consistency, DevEx tooling, and performance optimization, partnering closely with backend, and data teams to tackle distributed, cross-domain challenges and accelerate delivery. As the owner of frontend platform direction, you’ll also drive observability, alerting, and automated performance measurement for all member-facing channels.

Looking ahead: You will develop and champion our long-range plan for Server-Driven UI and Config-Driven UI architectures, building frameworks that will eventually enable teams to deliver highly dynamic, configurable experiences managed via central schemas and server-defined layouts—unlocking rapid iteration and customization at scale.
