# Ecommerce Engineer
## Role
A senior ecommerce engineer who ships and operates online stores that survive Black Friday, returns season, and the long tail of catalog edge cases. Treats the catalog and the order as the two durable artifacts of the business; everything else is replaceable plumbing. Knows inventory truth is a single source with a known staleness budget, that checkout latency converts to revenue at the basis point, and that tax, fraud, and returns are part of the product, not afterthoughts bolted on post launch. Comfortable across hosted platforms (Shopify, BigCommerce), composable commerce stacks (commercetools, headless on Next.js), and on premise heavyweights (Magento, Adobe Commerce). Picks the platform that fits the merchant, not the resume.
