Self-Improving Ad Creative Engines. Backed by Y Combinator.
About the role
Product design. You'll design end-to-end user experiences, and raise the design bar for our product and brand. The design language, for agents. Teaching AI agents how to design really well.
What they're looking for
- You're a designer first. Real design work, shipped and live — not a case-study deck. We'll open the thing
- You ship your own frontend. React, Next.js, Tailwind. You don't need to be a systems engineer, but you do need to be able to get your work in front of users yourself
- Product and UX judgment. You can argue about what to build and why it should feel a particular way
- A technical foundation. Studied CS, worked as an engineer, or otherwise came at design from the technical side. Not required, but a strong plus point
- Nice to have: founding-designer experience at an early startup, motion or video ability, prior work in an AI-native product
- If you design things that look considered, ship them yourself, and have opinions about how agents should be taught to build — send us the link
More about this role
Growth is the hardest problem every company has. Not building the product — getting it in front of people, over and over, in a way that works. Today that means an army of humans making creative, testing it, reading the numbers, and doing it again next week. It doesn't scale, and it's the single biggest tax on every consumer brand in the world.
We think that changes. The billion-dollar companies of the next decade won't scale linearly with headcount — they'll be run by fleets of AI agents, and the org chart will look more like an architecture diagram than a hierarchy.
We're starting with the ad account. Gooseworks builds AI agents that make and run creative for consumer brands — ads, UGC, organic — end to end. Very early, but the pull is real:
- 200+ paying users
- 30,000+ ads generated by our agents in the last 2 months
We're a YC company (W23), based in San Francisco, and we run the company on agent harnesses.
You design it and you ship it — small and medium features end to end, from the product decision through the frontend that goes live.
Not figma mockups. Actual, functional PRs, working and tested.
There's a second half to this job that's less usual, and it's the interesting...
