Read the overview of this opportunity to understand what skills, including and relevant soft skills and software package proficiencies, are required.

This is a senior individual contributor role. Rather than managing a team, you will operate as the strategic lead for your portfolio: building and executing multi-quarter account plans, identifying and closing growth opportunities, and partnering closely with internal operations, product, and technical teams to ensure we deliver against revenue commitments. You will be the voice of your partners inside SE7EN and the voice of SE7EN in the market.

This role is ideal for someone who thrives in an ambiguous, fast-paced environment, excels at building executive-level relationships, and is energized by owning a number.

Strategic: SE7EN values deep partnerships with the media owners who monetize through our SSP. You will move beyond day-to-day account management to build durable, multi-quarter strategic plans for each of your Tier 1 partners grounded in a strong point of view on where the supply landscape is heading and how your partners should position for it.

Growth-Oriented: You treat your book as a business. You know where the revenue is today, where the upside sits, and what must happen to capture it. You are constantly seeking opportunities to add value, deepen integrations, and grow yield for your partners and for SE7EN.

Collaborative: To retain and grow Tier 1 supply accounts, you will work cross-functionally with product, technical teams, and internal operations to become a subject matter expert on the SE7EN platform and to make sure the commitments you make externally are ones we can operationally deliver.

Communicative: You will engage a wide set of partner and internal stakeholders at any given time and will be expected to communicate effectively in both directions. This is a highly visible, partner-facing role where building trusted relationships at the senior and executive level is essential.

Accountable: You own revenue outcomes for your portfolio. You forecast credibly, track delivery against targets and OKRs, escalate early, and drive issues to resolution without needing a perfect playbook.
