Build the order-orchestration engine that handles thousands of cross-border orders daily.

About the role

You will own the order-orchestration service that sits at the heart of our cross-border operations — the system that decides when an order is fulfilled, which marketplace handles it, and how customer service gets notified.

What you’ll do

  • Design and ship Go/Node services that orchestrate orders across multiple marketplaces.
  • Define service contracts with our operations team and our marketplace integrations.
  • Own observability — dashboards, alerting and runbooks for what you ship.
  • Mentor 2–3 mid-level engineers; review code thoughtfully.

What you bring

  • 5+ years building production backend services.
  • Strong SQL, comfortable designing schemas for high-throughput, multi-tenant data.
  • Experience with eventual-consistency systems — webhooks, queues, idempotency.
  • Clear written communication; you can explain a tradeoff in a paragraph.

Nice to have

  • Experience with eCommerce platform APIs (Shopify, Amazon SP-API, Rakuten, etc.).
  • Reading or speaking Japanese.
