About AssembledGreat customer support requires human agents and AI in perfect balance, and Assembled 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 roleAt Assembled, we're rebuilding how design and engineering create products from the ground up - a brand-new design system and the AI-native workflows that bring it to life. We're looking for a Software Engineer to lead the technical vision for that work: defining the architecture of the system, building the infrastructure around it, and helping shape the next generation of design-to-code workflows.
Working closely with our Design Systems Designer, you'll make foundational decisions that influence every product team at Assembled - from component APIs and token architecture to performance, accessibility, developer experience, and how AI coding agents generate production-quality UI.
What you'll do- Own the technical direction of our design system, from token architecture and components to tooling, testing, and adoption
- Shape how AI coding agents build UI, through component APIs, documentation, guardrails, and developer workflows
- Modernize our frontend foundations, including component architecture, tooling, and development patterns
- Raise the bar for frontend quality, including performance, accessibility, responsiveness, and interaction detail
- Build the infrastructure that keeps the system reliable at scale, including testing, visual regression, CI/CD, and versioned releases
- Establish frontend best practices across teams, helping engineers build more consistent, maintainable, and high-quality user experiences
- Influence product decisions early, surfacing technical constraints, tradeoffs, and opportunities throughout the design process
We're looking for someone who:- Has 3+ years of experience building frontend products, with meaningful ownership over architecture and technical direction
- Has owned or significantly evolved a design system used across multiple teams or products
- Has deep frontend expertise, including TypeScript, component architecture, and modern frontend tooling.
- Has raised the quality bar of a product, improving performance, accessibility, usability, and interaction design
- Has strong product and design instincts, with a sharp eye for craft and user experience
- Communicates clearly and collaborates effectively, especially across engineering and design
- Is excited about AI-assisted development workflows, and how design systems can help guide and accelerate AI-generated code
Nice to have- Experience with our full stack: React, Storybook, and data visualization libraries such as visx, D3, or Chart.js
- Experience building B2B SaaS or highly interactive, data-rich applications
Our U.S. benefits- Generous medical, dental, and vision benefits
- Flexible time off
- Monthly credits for professional development, general wellness, Assembled customers, and commuting
- Paid parental leave
- Catered lunches every day (M-F) and fully stocked SF office
- 401(k) plan enrollment
The estimated base salary range for this role is $160,000 - $270,000 per year. The base pay offered may vary depending on location, job-related knowledge, skills, and experience. Stock options are provided as part of the compensation package, in addition to a full range of medical, financial, and/or other benefits, dependent on the position offered.
