We're looking for a Senior Frontend Engineer (TypeScript/Angular/React) to help build and evolve the user-facing side of our ecommerce platform. You'll work on our existing Angular applications today while playing a key role in shaping our next-generation frontend: a single platform, potentially React-based, designed to deliver a fast, consistent experience across desktop, tablet, and mobile, including offline-capable and installable experiences.

You'll work closely with Product, Design, and backend engineers to turn complex B2B workflows into intuitive, performant interfaces. Beyond writing code, you'll mentor other engineers, help define frontend architecture and standards, and drive engineering best practices across the team.

• Design, develop, and maintain customer-facing web applications for buyers, sales reps, and brands.
• Help define the architecture of our next-generation frontend platform, including component design, state management, routing, data fetching, and build tooling.
• Evaluate and implement cross-platform approaches (Progressive Web Apps, React Native/Expo) to deliver a great experience across desktop, tablet, and mobile.
• Build offline-capable, resilient experiences for users working with intermittent connectivity.
• Build and maintain a reusable, accessible component library and design system.
• Maintain our existing Angular applications and help lead a possible migration to new technology, such as React.
• Collaborate with backend engineers to design REST and GraphQL APIs that are intuitive, efficient, and well-suited to frontend needs.
• Ensure frontend code meets PCI DSS and security requirements.
• Own frontend performance: bundle size, rendering performance, Core Web Vitals, and perceived responsiveness on real-world devices and networks.
• Champion engineering best practices including code reviews, automated testing, CI/CD, observability, and documentation.
• Use AI-assisted development tools (e.g., Claude Code, Cursor, GitHub Copilot) to accelerate delivery, while owning the correctness, security, and maintainability of everything you ship.
