About HappyRobot

HappyRobot is the infrastructure for enterprises to build and orchestrate AI workforces. Our AI workers don't just communicate - they make decisions, take action, and run operations autonomously across voice, email, and enterprise systems. Born in Y Combinator (S23) and backed by a16z and Base10 with over $60M raised, we power critical operations for global enterprises worldwide.

Our platform is battle-tested in the most demanding environments - where AI has real consequences. We started in logistics, built our own voice stack, models, and orchestration layer from the ground up, and are now bringing that infrastructure to every enterprise that runs the real economy.

You’ll collaborate closely with product, design, and engineering to shape the product in real time and ship quickly.

If you enjoy building beautiful, intuitive interfaces and sweating details, but also care deeply about performance, maintainability, and real users then this role is for you.

What You’ll Do

- Design and build high-quality, user-facing product experiences end-to-end

- Translate product ideas and UX concepts into clean, production-ready frontend code

- Own UI patterns, interaction design, and visual polish across the product

- Collaborate closely with engineers, designers, and product managers in tight feedback loops

- Rapidly prototype, iterate, and ship — balancing speed with craft

- Help evolve our frontend architecture as the product scales

What We’re Looking For

- Strong frontend engineering skills (TypeScript, React, Next.js)

- Excellent visual and interaction design taste. You care about spacing, motion, hierarchy,...
