Full Job Description

ABOUT ASSEMBLED Great customer support requires human agents and AI in perfect balance, and Assembled https://www.assembled.com/customers is the only unified platform that orchestrates both at scale. Companies like Canva, Etsy, and Robinhood use Assembled to coordinate their entire support operation — in-house agents, BPOs, and AI — in a single operating system. With AI Agents that resolve cases end-to-end, AI Copilot for agent assistance, and AI-powered workforce management that optimizes both human and AI capacity, Assembled helps teams deliver faster, better service while making smarter decisions about how to staff and automate. Backed by $71M from NEA, Emergence Capital, and Stripe, we're building the platform that makes AI and human collaboration actually work. THE ROLE In this role, you'll own the foundations our frontend is built on, include the infrastructure, tooling, and component system that the entire engineering team relies on. You'll set the standard for performance, quality, and best practices in the frontend and make it faster and safer for every engineer to ship great UI. You'll also partner closely with designers and PMs on the product itself. Our front-end stack consists of React and TypeScript, and we use Figma for design. We're in-person 5 days a week from our bright, airy offices in the Mission (San Francisco) and Chelsea Market (New York). RESPONSIBILITIES: - Own frontend infrastructure & deployment: Build and maintain the tooling our frontend runs on (bundling, linting, type-checking, testing setup, and CI/CD). You'll own the frontend developer experience end to end. - Build and evolve our component system: Design and maintain our design system and component library, ensuring we focus on clean component APIs, theming, accessibility, and documentation and drive adoption so teams build on consistent, high-quality building blocks. - Champion frontend performance & best practices: Set and uphold patterns for performance, code quality, and archite
