• Design and evolve scalable web experiences, services, APIs, and data models for Browse, Navigate, Preview, App Shell, window chrome, and shared web capabilities.
• Make architecture and scope tradeoffs balancing customer needs, delivery constraints, reliability, performance, security, privacy, and maintainability.
• Improve observability, testing, incident readiness, and on-call health; lead debugging and production-risk decisions when systems fail.
• Use approved AI and automation tools for implementation, testing, debugging, documentation, and operational workflows, validating outputs to preserve engineering quality.
• Align cross-team dependencies and create leverage through reusable components and services, design and code reviews, runbooks, technical documentation, and mentoring.

• Experience designing, shipping, and operating large-scale, customer-facing web applications and multi-component systems.
• Strong frontend engineering skills with TypeScript or JavaScript and modern web frameworks such as React, plus experience with at least one backend language such as Python, Go, Java, or C++.
• Demonstrated end-to-end ownership of ambiguous, multi-phase initiatives, including adjusting scope based on customer, business, and technical constraints.
• Experience making architecture tradeoffs across frontend systems, APIs, data models, reliability, performance, observability, and production operations.
• Ability to learn unfamiliar systems, codebases, and approved AI or automation workflows while validating generated output for correctness, security, privacy, and maintainability.

• Experience with large-scale content, file, collaboration, or productivity systems.
• Deep experience with React and TypeScript together with backend APIs, services, and data modeling.
• Experience with AI-assisted product experiences, recommendation systems, or operational automation.
• Experience leading cross-team migrations, staged rollouts, or platform integrations and improving SLOs, observability, or test strategy.
