The posting

Workana is the largest remote work platform for talent in Latin America. Our division focuses on matching exceptional professionals with leading and innovative companies around the globe.

About the Client

Toolbox Widget is a U.S.-based company that designs and manufactures innovative tool organization products, tool mats, and shop storage solutions. With an expanding product catalog and partnerships with major industry players like Snap-On, the company is rapidly growing its global footprint across direct-to-consumer, retail, and digital marketplace channels.

We are looking for a hands-on E-Commerce Marketplace Manager to take full ownership of Toolbox Widget’s third-party digital marketplace strategy, bringing their Amazon store in-house and launching their presence on Walmart.com from the ground up.

This is a fully remote opportunity for professionals based in Latin America, working closely with an international team in an English-speaking environment.

Role Overview

As the E-Commerce Marketplace Manager, you will serve as the single accountable lead for ToolBox Widget’s marketplace channels, managing catalog integrity, listing content, platform advertising, inventory coordination, and overall P&L performance across Amazon and Walmart.com.

You will lead the end-to-end launch of Walmart Marketplace within the first 120 days while transitioning Amazon management fully in-house. You will work directly with executive leadership, internal content creators, and pay-per-click specialists to drive marketplace profitability, optimize contribution margins, maintain pricing discipline across channels.

Selection Process

The process usually consists of 3-4 stages and takes on average 2-3 weeks to be completed, depending on eventual additional technical rounds or conversations.

  • Initial interview with Workana's recruiting team
  • Technical interview with the client
  • Cultural fit interview with the client's manager

As Workana has multiple clients, if you pass the first round with Workana's recruiting team, you may also be considered for other relevant opportunities if the initial opportunity does not move forward.

Responsibilities

  • Own and execute the end-to-end strategy, listing setup, and launch of ToolBox Widget’s catalog on Walmart Marketplace.
  • Transition Amazon Seller Central operations (FBA and FBM) in-house, establishing SOPs and eliminating agency reliance.
  • Build and manage per-SKU contribution margin P&L models accounting for platform fees, ad spend, storage costs, and freight.
  • Create, optimize, and manage Sponsored Products, Brands, Display, and Walmart Connect advertising campaigns.
  • Ensure 100% catalog integrity, rich media, A+ content, variations, and compliance across all active SKUs on all marketplaces.
  • Manage inventory forecasting, reorder triggers, and stock allocation in coordination with 3PL partners (ShipBob) and internal teams.
  • Coordinate marketplace pricing with DTC and wholesale strategies to prevent MAP erosion and channel cannibalization.
  • Troubleshoot seller account issues, including case creation, listing suppressions, Brand Registry, and reimbursement claims.

Requirements

  • 3+ years of hands-on experience as an Amazon Seller Central operator managing account health, listing creation, and Brand Registry.
  • Demonstrated hands-on experience with Walmart Marketplace, including item setup, catalog health, WFS vs. seller-fulfilled setups, and Walmart Connect.
  • Direct hands-on experience running and optimizing PPC campaigns on both Amazon Seller Central and Walmart Connect.
  • Strong P&L literacy with the ability to analyze unit economics, contribution margins, and platform fee structures.
  • Experience with e-commerce inventory forecasting, stock allocation, and 3PL fulfillment operations.
  • High level of autonomy, ownership mindset, and experience collaborating with cross-functional creative and marketing teams.
  • Fluent English is mandatory, as the role involves regular collaboration with an international team.
  • Must be based in Latin America.

Bonus Points

  • Prior experience transitioning marketplace management from an external agency to an in-house operation.
  • Familiarity with Shopify integration and multi-channel e-commerce architectures.
  • Experience in the tools, hardware, automotive accessory, or consumer hardlines categories.
  • Hands-on experience selling on additional platforms such as eBay, Target Plus, or international marketplaces (UK, AU, CA, EU).

Benefits

  • Competitive compensation in USD
  • Fully remote work within Latin America with flexible time schedules
  • Career growth with international clients and dynamic projects
  • This is a long-term independent contractor agreement with no additional benefits such as paid time off, health insurance, etc.

Why it works

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
