📦 Managing enterprise brands · Individual contributor, no direct reports
As one of the top 5 Amazon sellers in the US, Luminize runs the full growth layer for 80-100 consumer brands. As a Principal Account Manager / Principal Brand Manager you own a book of a handful of enterprise brands as their primary strategic partner. You own the forecast, PPC strategy, catalog, and more through the quarterly business review, with our advertising, content and supply chain specialists executing alongside you.
This is a senior individual-contributor role. You will own a book of brands, not a team of people.
What you will actually own
The forecast. You set it, you defend it, and you are the one explaining the variance.
The advertising strategy , executed by our advertising strategists. You set the direction and own the number; they are in the console.
The QBR. You run the room. These are S-tier clients and the expectation is that you handle them with minimal involvement from leadership.
The escalation. When something breaks across catalog, supply chain and content at once, it routes to you and the fix is yours to design.
The growth case. You find the opportunity in the account before the client asks for it.

Base salary, no bonus or equity.
