About the role

Our team is small, the impact is large, and we ship real product to real users frequently.

Design compelling, clear UI/UX and produce high-quality mocks that demonstrate strong product taste.
Turn design mocks (yours or others') into pixel-perfect, production-ready frontends using modern web tech.
Iterate on existing interfaces by improving layout, interaction quality, motion, and design consistency.
Work closely with engineers, partners, and stakeholders - you'll own the design and implementation of features end-to-end.
Contribute to design systems, component libraries, and patterns that raise the bar for frontend quality across YC.
Strong UX and visual design skills with proven taste and craftsmanship.
Frontend engineering experience - comfort building real UI in React, TypeScript, and modern CSS.
Ability to move fluidly between design tools (Figma, etc.) and frontend code.
Comfort with ambiguity: you'll often define your own scope and drive things forward with little direction.

Background in internal tools, admin dashboards, or developer-facing products.
Why this role at YC
We work on a small, tight-knit team where your decisions matter, and you'll ship real product quickly, often interacting directly with users.
You'll also be plugged into the heartbeat of the startup ecosystem, surrounded by founders and builders working on the hardest problems.
You must live in the SF Bay Area or be willing to relocate.
