Staff Software Engineer, Frontend Platform Architecture and Infrastructure

About the role

The Staff Software Engineer will serve as the front-end platform authority for Wayfair's customer-facing Next.js monolith. They will own and drive front-end standards, tooling, and governance across teams in the Customer Tech and Promotes organizations. They will lead the ongoing Next.js and React major version upgrade, diagnose performance degradations, drive resolution, and align contributing teams. They will define and evangelize front-end infrastructure best practices for performance, scalability, and developer experience.

Responsibilities

• Serve as the front-end platform expert and technical authority for Wayfair's customer-facing Next.js monolith
• Own and drive front-end standards, tooling, and governance across teams in the Customer Tech and Promotes organizations
• Lead the ongoing Next.js and React major version upgrade — diagnose performance regressions, drive resolution, and align contributing teams
• Define and evangelize front-end infrastructure best practices for performance, scalability, and developer experience
• Act as a community leader for Wayfair's front-end engineering community, influencing technical direction beyond your immediate team
• Partner closely with engineering leads across teams to ensure platform consistency and scalability as the codebase grows

• Mentor engineers across seniority levels and contribute to raising the front-end engineering bar across Customer Tech

Requirements

• 8+ years of software engineering experience with deep expertise in front-end infrastructure
• Substantial, hands-on Next.js experience at enterprise scale — you've operated and scaled a large Next.js application, not just built with it
• Strong React and TypeScript fundamentals with the ability to reason about performance at the framework level, not just the component level
• Demonstrated experience with front-end platform and infrastructure work: build tooling, scalability, performance optimization, monorepo governance, or similar
• Track record of architect-level autonomy — defining technical roadmaps, making opinionated decisions, and bringing engineering communities along
• Experience driving technical standards across large engineering organizations with many contributing teams
• Strong communicator who can build consensus across engineering leadership and serve as a visible technical voice
• Comfort operating mid-stream in complex, high-traffic systems where the stakes are high and the answers aren't obvious
• Familiarity with performance observability tooling (Datadog, Lighthouse, Web Vitals) and experience navigating major framework upgrades in active production environments is a plus
