Senior Principal Engineer

ImpactShipt is transforming the way people shop for everyday essentials — and the Member Marketplace is the front door to it all. As a Senior Principal Engineer on the Member Marketplace team, you’ll lead the charge in architecting and scaling the core user-facing experiences across desktop, mobile web, and native apps. This is a high-impact, high-visibility role where you’ll shape the technical direction of the platform that millions of members interact with daily.

This is a career-defining opportunity for an engineer who thrives at the intersection of technical excellence, system design, and customer-centric product thinking. You’ll set the tone for engineering excellence, champion performance and accessibility, and lead cross-functional efforts to modernize and future-proof our frontend platforms.

In this role you will own the technical vision and architectural strategy for Shipt’s Member Marketplace experience across web and mobile and be responsible for designing and evolving component libraries, design systems, and cross-platform UI foundations to support multiple teams and product surfaces. You will lead modern React and React Native application architecture, using Next.js for SSR/SSG and Apollo GraphQL for data orchestration and scale best practices for state management, routing, async data handling, lazy loading, and cross-device responsiveness. Additionally, you will collaborate across domains to solve complex problems that span backend, data, and mobile platforms, influence the frontend platform strategy through contributions to performance monitoring, observability, and alerting practices, and contribute to clean GraphQL schema design, GraphOS federation strategies, and scalable data-fetching paradigms.

What You’ll Need to Be Successful

Core Technical Expertise

• 10+ years of experience in frontend engineering with a strong foundation in JavaScript/TypeScript

• Deep knowledge of React, React Native, and Next.js for building modern, scalable SPAs and mobile-first applications

• Strong understanding of Apollo GraphQL and best practices around client-side schema management, caching, and federated GraphQL

• Experience with component libraries, design systems, and tools like Storybook, Figma, and Chromatic

• Mastery of CSS strategies: CSS-in-JS, Tailwind, SCSS, CSS Modules, or equivalent

• Fluency in cross-platform architecture and experience with mobile-specific constraints

• Strong grasp of state management patterns (Redux or context API)

• Expertise in building and scaling frontend CI/CD pipelines

• Familiarity with Web Vitals, Lighthouse, Core Web performance metrics, and observability tools (Datadog, New Relic, Sentry)
