Designed to replicate how top-performing reps execute deals. Trusted by revenue teams at Saviynt, Everlaw, Allego, Superhuman, Sirion and more.

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

Must-have:

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

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

What We Offer

Work on genuinely hard AI problems, not CRUD apps

Direct access to founders

Access to best-in-class dev tools and AI assistants to help you do your best work
