Own a category like it is your own business.
Location: Remote, based in Spain
Compensation: $42,000–$55,000 USD/year base, plus performance bonuses tied to category profit and in-stock rate
LifeSupplyUSA is one of the fastest-growing e-commerce retailers of household essentials in the US: air filters, HVAC filters, extension cords, and home goods. We sell across Amazon, Walmart, Shopify, and Canada with a lean, high-performance remote team, and we are building a sharper, more scalable company with better dashboards, cleaner SOPs, and real ownership.
This is not a Catalog Manager role in the usual sense of listing maintenance or backend cleanup. This is a Category Merchant role: you own a P&L;, you own pricing and in-stock calls, and you are measured on margin and category profit, not on tasks completed. If you are looking for your first marketplace role or a purely execution-level position, this is not it.
THE ROLE

Cualquier información adicional que necesite para este trabajo se encuentra en el texto a continuación. Asegúrese de leerla detenidamente y luego envíe su solicitud.




You will own a defined block of our catalog (starting with extension cords, our largest category) like a P&L.; You will know your category and your top competitors cold, watch your listings every day, and make the pricing, inventory, and advertising calls that protect rank and margin.
This is a judgment and ownership role. Not data entry. Not catalog cleanup. Not dashboard watching.
WHAT YOU WILL OWN
Category P&L;: in-stock rate, contribution margin, TACOS, and category profit. You run it like an owner.
Daily monitoring of your top SKUs: competitor pricing, deals and lightning deals, stock positions, Buy Box, and listing health.
Pricing decisions within a clear rule set, including our low-stock governor (when a winner runs low, you decide whether to raise price or pull ad spend to protect rank instead of going out of stock).
In-stock discipline on core winners, working with forecasting and sour
