We’re looking for a Senior Ad Operations to join our team in São Paulo and play a key role in shaping the future of neuro-contextual advertising at a global scale.

Who We Are

Seedtag is the leading Neuro-Contextual Advertising Company.
We are redefining how advertising works in a privacy-first world by moving beyond keywords and cookies, towards understanding human emotion, intent, and context.

Powered by advanced AI and neuroscience, our proprietary technology, Liz, delivers a deep, human-like understanding of content and attention. This enables brands to connect with audiences at the right moment, in the right mindset, with ads that are relevant, engaging, and respectful of the user experience.

Founded in 2014 by two ex-Googlers, Seedtag has grown into a global company with 500+ Seedtaggers across 17 countries, backed by €250M in funding, and expanding rapidly across the open web and Connected TV.

We’re not just building technology, we’re rewriting the rules of advertising.
