Staff Software Engineer, Frontend Platform Architecture and Infrastructure

Staff Software Engineer

Wayfair's Customer Tech organization is at the heart of everything our customers experience at Wayfair.com. We own the Next.js-based monolith that powers the full customer-facing storefront — the platform that hundreds of engineers build on every day to bring the world's largest online home destination to life. We are a team of builders, architects, and community leaders who believe that great infrastructure unlocks great product. We set the standards, govern the codebase, and ensure every team shipping into our monolith has the tools and guardrails to move fast and do it right.

We are looking for a Staff Software Engineer to serve as the front-end platform authority for Customer Tech. You'll be embedded at the platform layer, working autonomously to drive technical direction across approximately 200 engineers contributing to a single codebase.

You'll step into an active, high-stakes environment: we're in the middle of a major Next.js and React upgrade, and we need someone who can go deep, diagnose performance degradations, align front-end teams across the organization, and govern our way through to a stable, scalable outcome. This is a role for someone who thinks at the architect level and leads through technical credibility.

You'll act as a community leader and technical authority across Customer Tech and the broader Wayfair front-end engineering community — partnering with engineering leads, mentoring engineers across seniority levels, and establishing patterns that scale to hundreds of contributors.

What You'll Do

• 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
• Identify and address architectural gaps, establishing patterns that can scale to hundreds of contributors
• Mentor engineers across seniority levels and contribute to raising the front-end engineering bar across Customer Tech

We Are A Match Because You Have

• 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
