Senior Amazon Marketing & Account Manager (Seller Central)

About Gravity Defyer

Gravity Defyer is a direct-to-consumer footwear brand focused on medical and orthopedic footwear — shoes engineered for comfort, support, and everyday wear for people who need more from their footwear than the average brand delivers. We've built a loyal customer base through our own DTC channel, and Amazon is our next major growth engine.

We're looking for a proven Amazon expert to own the channel end to end — someone who has personally grown Amazon accounts, knows Seller Central inside and out, and treats our sales numbers like their own.

The Role

You will own Gravity Defyer's entire Amazon business: strategy, advertising, listings, brand content, inventory, account health, and P&L. This is not a support role and not an agency-coordination role — you are the operator. Your job is simple to describe and hard to do: grow our Amazon sales and revenue profitably, starting in your first month, not after a long ramp-up.

You'll have real ownership, direct access to leadership, budget authority within agreed targets, and the freedom to run the channel the way a top-tier Amazon operator would.

Key ResponsibilitiesAccount Ownership & Strategy

• Own the complete Amazon Seller Central account (FBA and FBM) for the U.S. marketplace, with a roadmap to expand into Canada, UK/EU, and other marketplaces.
• Build and execute a 12-month Amazon growth plan with clear revenue, margin, ranking, and market-share targets.
• Own the Amazon P&L: revenue, ad spend, FBA fees, storage, returns, and net contribution margin.
• Report weekly and monthly on performance, with clear insight into what's working, what isn't, and what you're changing.

Amazon Advertising (PPC)

• Plan, launch, manage, and optimize all Amazon Ads campaigns: Sponsored Products, Sponsored Brands, Sponsored Display, and Amazon DSP where appropriate.
• Manage the ad budget to hit TACoS/ACoS and total-sales targets — scale what works, cut what doesn't.
