Senior Staff Software Engineer-Frontend

About the role

The Senior Staff Frontend Engineer on the Customer Experience team at Scout Motors will set the technical direction for the customer-facing experiences that define how people buy a vehicle with us. This role involves defining and driving the frontend architecture across the customer purchase journey, building high-quality, performant customer-facing experiences, and leading the evolution of our shared component library and design system.

Responsibilities

• Define and drive the frontend architecture across the customer purchase journey, making deliberate decisions about component design, state management, rendering strategy, and application structure that the team builds on for years.
• Build high-quality, performant customer-facing experiences end-to-end, from pixel-perfect UI implementation through API integration, error handling, and production monitoring.
• Own the frontend performance and reliability bar: Core Web Vitals, load time, rendering performance, and the resilience of the UI when backend services or third-party integrations are degraded.
• Lead the evolution of our shared component library and design system, ensuring consistency, accessibility, and developer ergonomics across all customer-facing surfaces.
• Partner deeply with product and design, shaping interaction patterns and UX decisions from a technical perspective and pushing back when proposed experiences would compromise performance, accessibility, or maintainability.
• Drive cross-team frontend initiatives, establishing standards and patterns that other teams building customer surfaces adopt and benefit from.
• Conduct deep code and design reviews, author frontend architectural decision records, and establish the engineering practices that define quality for the team.
• Mentor and grow senior frontend engineers, expanding their architectural thinking, design system instincts, and ownership of the customer experience.
• Champion accessibility and inclusive design as first-class engineering requirements, not post-launch afterthoughts.
• Champion pragmatic AI-assisted development, evaluating tools, setting team norms, and helping engineers use them effectively across the UI development lifecycle.

Requirements

We are looking for a Senior Staff Frontend Engineer with 12+ years of experience, a Bachelor’s or Master’s degree in Computer Science or a related technical field, and deep expertise in modern frontend technologies including WebGL, GSAP, Framer, and Astro, with a focus on building performant, maintainable systems. Expertise in React and TypeScript, including advanced patterns, performance optimization, and large-scale application architecture is also required. Proven experience owning and evolving component libraries or design systems at scale is essential. Strong instincts for UX and interaction design, thinking about the customer experience and not just the implementation, and mastery of frontend performance are key. Additionally, experience with Full-stack engineering experience - micro frontend architecture and mobile platform foundations (iOS, Android, React Native) is a plus.

Qualifications

Qualified candidates will have a proven track record of leading frontend technical strategy across teams, authoring RFCs, driving architecture reviews, and influencing peers and leadership. They should also have excellent communication skills, able to make frontend tradeoffs legible to product, design, and non-frontend engineering stakeholders.
