The Sr Account Executive is a critical quota-carrying role responsible for driving new partnerships with agencies and brand-direct marketers.

Who you are: - 6-8 years of sales experience, ideally in programmatic, digital advertising or AdTech. - Proven experience selling into media agencies and/or brand-direct marketers, with the ability to navigate multiple stakeholders and complex deal cycles. - Strong hunter mentality — history of balancing prospecting, working warm leads and closing net-new business. - Track record of success in quota-driven environments. - Skilled communicator able to translate technical, multi-product and platform based concepts for executive-level audiences. - Established relationships with small to mid-size agencies or brand-direct marketers (a strong plus).
