Product Designer

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.

On the publisher side, you'll design the SDK integration experience - how publishers describe their surfaces, configure preferences, and see value from Koah.

You'll also shape the ad format system itself - how formats compose, adapt, and render across surfaces.

What You'll Do

• Design the advertiser experience end-to-end - campaign creation, AI-assisted creative tools, reporting
• Shape how advertisers and campaign agents collaborate to produce and deploy ad creative at scale
• Design the publisher integration experience - SDK onboarding, surface configuration, performance dashboards
• Contribute to the ad format library - how formats adapt across different rendering contexts
• Connect the dots across advertiser tools, publisher surfaces, and end-user ad experiences

You Might Be a Fit If

• 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
