Director, Supply Account Management

SE7EN is seeking a Director, Supply Account Management to join our US team. In this role, you will own a book of approximately 10 Tier 1 supply partners our largest and most strategically significant media owners and carry full accountability for their retention, growth, and long‑term success on our platform.

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.
