Why This Role Exists
SiftHub reaches users across multiple surfaces: a web app, a Chrome extension that surfaces AI intelligence mid-call and mid-workflow, a Microsoft Office add-in, and a Google Sheets add-on. The frontend experience is the product. We need a senior engineer who can own it across all of these: architecture, performance, and the bar enterprise users will hold us to.

What You’ll Own
• The Chrome extension, Office add-in, Sheets add-on, and React/TypeScript web app: architecture, performance, reliability, and cross-surface consistency




• Component systems and design token infrastructure the team builds on
• Frontend performance: load times, rendering, memory, and extension lifecycle
• Integrating AI outputs into clean, responsive UIs, working closely with NLP and backend engineers
• The frontend quality bar: code reviews, patterns, and technical standards

•

Must-have
• 4+ years of production experience with React and TypeScript
• Strong command of the modern frontend stack: state management (Redux, Zustand, or similar), Webpack or Vite, and testing with Jest/Vitest, React Testing Library, or Playwright
• Deep experience with at least one non-web surface (browser extensions, Office add-ins, or Google Workspace add-ins), including its platform constraints, lifecycle, and edge cases
• Robust opinions on component design and state management, with the ability to reason about trade-offs, not just implement
• Hands-on performance profiling and opt
