Full-Stack Developer for Custom E-Commerce Automation Platform (Amazon API, Print Workflow)

We are a growing greeting card and print-on-demand brand selling across Amazon marketplaces. We're building an internal software tool to automate our design-to-listing pipeline, manage Amazon orders, generate shipping labels, and consolidate print orders for production.

A system to ingest and process design files (PNG, PSD, etc.) and generate automated size and color variations

A listing generator that interfaces with Amazon SP-API (title, keywords, bullets, images)

A backend service to create shipping labels (Amazon Buy Shipping or external APIs like DHL)

A reporting dashboard for our print shop: summarizing SKUs, order volume, and batching production

A management dashboard to track listings, orders, issues, and workflow status

• Frontend: React (TypeScript)
