Native ads powered by real-time intent matching — not borrowed from the last era. The monetization layer for AI apps. Backed by South Park Commons.
About the role
We're looking for a product designer to own the advertiser and publisher experiences – the creative tools, dashboards, and integration flows that make Koah work for both sides of the marketplace. On the advertiser side, we're building toward a world where campaign agents do the heavy lifting – generating creative, selecting formats, optimising toward goals – and advertisers steer with goals and guardrails. You'll design the tools that give advertisers that power.
What they're looking for
- You think in systems and can balance immediate user needs with long–term product vision
- You've designed for multi–sided products – marketplaces, developer tools, ad platforms, or similar
- You're excited about designing AI–augmented workflows, not just traditional dashboards
- You care about craft because it compounds into trust
- You're comfortable at the design–engineering boundary – schemas, structured data, component APIs
- You're comfortable moving fast without a full spec and drive clarity through design
More about this role
Koah is building AI–powered ad formats that work across any surface. In a chat app, a Koah ad feels like part of the conversation. On a publisher's website, it feels like editorial content. In a sidebar, a feed, an email – it adapts its layout, density, and tone to belong wherever it appears.
We're using AI to make ads better everywhere – composing the right format for the right surface with the right content in real time.
We're backed by Theory Ventures, live in AI apps serving millions of users, and we recently closed our Series A .
