Do you thrive in a role that dives deep into hands-on Amazon execution while steering high-level channel strategy?

Have you successfully scaled 7- or 8-figure Amazon Seller Central accounts in the dietary supplement space while navigating strict FDA/FTC compliance?

Are you an Amazon SME who excels at managing agencies, mastering PPC/SEO, and taking total ownership of account profitability in a fast-paced, remote environment?

If you answered yes to these questions, we want to talk to you.

We are a high-growth, mid-sized dietary supplement brand seeking a hungry, operator-first Amazon Marketplace Manager to assume end-to-end commercial ownership, operational execution, and net profitability of our Amazon Seller Central (3P) account. Balancing hands-on execution with high-level channel strategy (roughly 70/30), you will serve as our internal Subject Matter Expert (SME), offloading daily operations from senior leadership to drive revenue in a fast-paced, remote environment.

In this role, you will own keyword ranking and Amazon SEO, manage PPC campaigns, optimize listing efficiency, strictly enforce dietary supplement regulatory compliance, and direct our external agency partner to maximize output.

Organics Ocean is a premium DTC supplement brand empowering health through science-backed, clean, and effective products. We are building a trusted wellness authority rooted in transparency, education, and long-term customer loyalty.

We operate in a high-growth, fast-paced environment where we constantly test, optimize, and innovate. Our team consists of high-performing operators who move with urgency and take pride in their craft. We maintain a collaborative, low-ego culture where feedback is direct, expectations are clear, and strong ideas win regardless of title. We believe our next stage of expansion requires A-players who thrive in ambiguity and hold a high bar for excellence.
