The Role

You will own the kataoka e-commerce platform end to end — its architecture, performance, integrations, and day-to-day operations.

• Configure and maintain payment systems, tax logic, and shipping integrations
• Oversee SEO structure and implement ongoing optimizations
• Manage marketing and analytics integrations
• Coordinate with the Tokyo atelier and New York boutique to ensure the platform accurately reflects current inventory, pricing, and brand presentation
• Identify and communicate technical debt and improvement opportunities to leadership
• Lead the eventual migration from CS-Cart to Shopify, including scoping and execution
• Internal IT support as needed
