Senior Manager, Advertiser Partnerships & Growth.

About the Role

Were looking for a proactive, commercially sharp Senior Manager, Advertiser Partnerships & Growth to own one thing above all: the success of our advertisers, so they win with us, spend more, and stay.

Advertisers reach us through several paths, directly, through agencies, or through network platforms. These are routes to the advertiser, not boundaries on the role. Whoever holds the budget and wherever they sit, this role owns their outcome.

This is a growth role, not an account-servicing one. Check-ins and reviews are the vehicle, not the job. The job is making advertisers successful and turning that success into incremental spend, actively managing the people who control budget, growing what they spend, and keeping it from quietly eroding.

What Youll Own

Advertiser growth. Own the success and growth of advertisers across every path to them, direct, agency-managed, and network-intermediated, in any market. Win incremental spend inside existing relationships (new categories, more campaigns, larger budgets, better terms), and convert warm inbounds and referrals into growing accounts.

Agency growth. Grow agency relationships as a multiplier, expand existing agencies into their wider advertiser portfolios, and develop agencies as an ongoing channel that brings advertiser budgets over time. One agency relationship can unlock many advertisers; treat it accordingly.

Identifying the right advertisers. Use performance data and cross-network visibility to spot which advertisers are worth winning, where demand is underserved, and which categories are converting, then bring them in through the relationships and channels you own.

Networks as a growth lever. Work network-platform relationships to grow the advertisers reachable through them, securing offer visibility, placement, and better terms that drive volume. You own the commercial side; Ad Operations owns integration.

Active book management. Read the performance curve and act on it, reactivate declining advertisers before they churn, respond where competitive terms are costing volume, and build growth plans against each advertisers goals (ROAS, CPA, conversion).

Coordination. Ad Operations (delivery), and Publisher Success (mobilizing the right publishers behind priority advertisers) so opportunities move fast and nothing falls between teams.

Leadership, as it scales. Build and lead the function as the book grows, and set a culture of commercial ownership where a warm opportunity is advanced, not deflected.
