Kramer America, Inc. | Smartliner USA

About Us

We're an established direct-to-consumer automotive aftermarket brand selling custom-fit vehicle accessories online and across major marketplaces, with a large, fitment-specific product catalog. Company name is shared once we're in direct conversation with candidates.

The Role

We're hiring a Shopify & Marketplace Manager to own our entire online selling footprint: the Shopify DTC storefront itself, and every marketplace channel built on top of it — Amazon (Vendor Central and Seller Central/FBA/FBM), Walmart Seller Center, and eBay. This is a hands-on, technical role. You should be comfortable inside the Shopify Admin at an expert level — themes, apps, metafields, basic Liquid/HTML/CSS — and equally comfortable running the day-to-day of Amazon, Walmart, and eBay seller operations. Coding ability is a strong plus: the more you can build, fix, and customize yourself, the less this role depends on outside developers.

Responsibilities

Shopify site

• Own day-to-day Shopify Admin operations: theme edits, page builds, app configuration and integrations, site performance and uptime

• Troubleshoot and resolve site issues — broken pages, app conflicts, checkout errors, tracking/GTM breaks — without always waiting on a developer

• Manage the ~1,300-SKU catalog structure: collections, metafields, variants, and product data integrity

• Write or edit basic custom code (Liquid, HTML/CSS, light JavaScript) for site fixes and enhancements

• Coordinate with outside developers or agencies on larger builds while handling day-to-day changes in-house

Marketplaces

• Own the Amazon Vendor Central relationship: purchase orders, chargeback disputes, co-op terms, A+ content

• Own Amazon Seller Central operations: FBA inventory and replenishment, FBM fulfillment workflows, fee management

• Own Walmart Seller Center: listings, fulfillment, Walmart Connect advertising, policy compliance

• Own eBay Seller Hub: listings, Promoted Listings, policy compliance

• Keep fitment data, pricing, and inventory in sync across Shopify and every marketplace channel

• Monitor Buy Box win rate, account health, and listing suppressions; resolve issues quickly

• Report weekly/monthly on channel-level performance, fees, and site health



What You Bring

• Genuine, hands-on expert-level experience across all of: Shopify Admin, Amazon Vendor Central, Amazon Seller Central (FBA/FBM), Walmart Seller Center, and eBay Seller Hub — not just one or two of these

• Comfort reading and writing basic code (Liquid, HTML/CSS, light JavaScript); any app-building or API integration experience is a strong plus

• Experience managing a large, fitment-based or variant-heavy product catalog

• Strong troubleshooting instincts — you can diagnose a broken listing, a tracking issue, or a site bug yourself before escalating

• Excellent organization across many concurrent platforms and workstreams

Compensation

$80,000–$110,000 base, depending on experience — flexes higher for candidates with strong coding/development skills — plus
