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 add-in for Office users, and a Chrome extension for Google Sheets. The frontend experience is the product. We need an 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 SiftHub Chrome extension, Microsoft add-in, and React/TypeScript web application layer — architecture, performance, reliability, and cross-surface compatibility (including Chrome extension APIs, Office add-in constraints, Google Sheets integration, and web app parity)
• Component systems and design token infrastructure that the team builds on
• Frontend performance: load times, rendering, memory, and extension lifecycle
• Collaboration with NLP and Backend engineers to integrate AI outputs into clean, responsive UIs
• Code quality bar: reviews, patterns, and technical standards for the frontend team

Experience & Core Skills

• Bachelor's or Master's degree in Computer Science or a related field, or equivalent practical experience
• 1-3 years of production experience with React and TypeScript
• Strong understanding of modern frontend stack including React, TypeScript, Redux or Flux, Webpack, and testing frameworks such as Jest, Mocha, Enzyme, or React Testing Library
• Experience building for platforms beyond web apps such as browser extensions, Office add-ins, or spreadsheet integrations. You understand platform constraints, lifecycle, and edge cases across Chrome Extension APIs, Office.js, Google Sheets API, and service workers
• Strong opinion on component design and state management, with the ability to reason about trade-offs and not just implement
• Experience with performance profiling and optimization in production environments
• Writes tests as a core part of development, not as an afterthought
• Strong grasp of UI principles with the ability to build clean, accessible, and maintainable interfaces, and clearly articulate design decisions

Good to Have 

• Experience with content scripts, background workers, and extension messaging patterns
• Experience working with AWS and CI/CD tools such as GitHub Actions
• Experience at a B2B SaaS company with an understanding of enterprise UI expectations
• Exposure to AI or LLM-powered product surfaces

Who You Are

• You care about the last 5%, the micro-interactions, edge cases, and polish that separate good from great
• You push back on UX decisions when something does not feel right, and you have the design intuition to back it up
• You are energised by the ambiguity of early-stage product and can build a path when there is not one
• You take ownership end to end, from design review to production monitoring
• You communicate clearly across disciplines and can work effectively with designers, PMs, and backend engineers
