Mision: Lead Seedtag evolution from a promising start-up to a global unicorn

Seedtag has massively grown over the past years. We are now at an inflection point facing one of our biggest challenges yet: have a best-in-class ad-serving technology.

We are looking for a talented Product Owner to lead this revolution. It’s responsibilities will include:

  • Create the new Seedtag buying ecosystem: Seedtag has its own publisher network to serve ads. We now want to go beyond that to be able to serve ads in space that are currently beyond our reach. The ideal candidate needs to be comfortable around SSP, DSP, programmatic buying, header-bidding and any other technology that will allow Seedtag to buy inventory outside our current network. Additionally, he/she will need to be comfortable with technological conversations with external providers, translating our needs to their tech teams and vice versa, allowing for the closest possible collaborations and seamless integrations
  • Ensure top-notch KPIs: Seedtag is characterized by its top-notch KPIs (VW, CTR, VTR, etc.). The expansion we are looking for should never be in detriment of our current standards in terms of KPIs. The ideal candidate will need to ensure that, being able to understand the root causes of possible problems, define A/B testing to confirm hypothesis and draw possible solutions together with the squad
  • Build up from a rock to a castle: As Product Owner, the ideal candidate will become part of a squad including developers, adtech experts and other types of profiles. Together with the Engineering Manager, the ideal candidate will need to understand development timings, be comfortable around MVPs to find possible short-cuts while understanding the tradeoffs made in the resulting technology, define future iterations to build up the best technology while ensuring its producing impact from the very beginning


Lead the revolution: As Product Owner, you will become the nexus from our Operations and Design team, Salespeople and external stakeholders to your squad. The ideal candidate will need to translate the needs of its stakeholders into development needs, bring both points of view together, align and lead the entire squad with the mission and vision of the company to bring Seedtag to unicorn

  • You have a degree in engineering or science
  • Have fluent command of Spanish and a good level of English
  • Are energetic, proactive and very eager to work in a startup environment
  • Have great communication skills and is not afraid to take risks
