• Work on the foundation that makes product teams faster, while staying connected to real user-facing experiences.
• Core Areas Of Ownership
• Web Architecture
• Define and evolve our frontend architecture (Next.js, SSR strategy, routing)
• Lead large-scale migrations (e.g., monolith to modern frameworks)
• Drive decisions around code structure, modularity, and scalability
• Performance
• Own Core Web Vitals (LCP, CLS, INP) and overall page performance
• Build and enforce performance guardrails (Lighthouse CI, budgets, monitoring)
• Develop real-user monitoring dashboards and insights
• Developer Experience
• Improve build systems, tooling, and local development workflows
• Design AI-forward developer workflows and productivity improvements
• Optimize build times, previews, and deployment pipelines
• Design System Infrastructure
• Build the foundations of the design system (tokens, theming, versioning)
• Define governance and scalability patterns (not component implementation)
• Platform Capabilities
• Build frameworks for experimentation (feature flags, client-side assignment)
• Support internationalization (i18n) and accessibility at scale
• Enable automated a11y validation in CI

What We're Looking For

• Strong experience building modern frontend applications using: React, TypeScript, Next.js
• A track record of shipping real, user-facing product features
• Experience owning shared systems or platform capabilities such as: Design system infrastructure (tokens, theming), Build tooling or developer workflows, Performance systems or observability, Experimentation or localization frameworks
• Ability to think beyond individual features and design systems other teams use
• You've worked on both product features and foundational platform systems
• You've led migrations, scaled frontend architecture, or improved performance at scale
• You bring a balanced mindset: shipping fast while building for the long term
• You're not just an infrastructure specialist—you understand end-user impact

Why This Role

• High impact across the entire frontend ecosystem
• Influence architecture, performance, and developer experience at scale
• Work on meaningful product experiences—not just internal systems
• Collaborate closely with product and engineering leaders
