The Opportunity Kargo is hiring a Senior Solutions Architect to be the technical authority that gets new advertising surfaces live on the Kargo platform—from first partner conversation to scaled, revenue-generating integration. This role sits at the intersection of engineering, partnerships, and product, owning the custom code, SDK work, and troubleshooting that turns novel ad environments into reliable inventory. When this role is firing, Kargo is expanding into new surfaces faster than competitors can follow. This is a hybrid role requiring onsite presence 4 days per week.
