We’re hiring a senior backend engineer to build and operate the systems behind that platform. You’ll work with our head of tech, data engineer, existing software engineer, frontend engineer and dedicated commerce product manager.

You’ll have direct ownership of business-critical software, from architecture and implementation through migration and ongoing operation.

• Commerce platforms: migrations from Shopify or another established commerce system

• Complex catalogs: configurable products, supplier inventory feeds or unique-item reservations

• Retail operations: workflows spanning ecommerce, showrooms and fulfillment
  Success in this role means accurate orders, payments and inventory; a controlled migration; and systems the team can maintain and extend.
