<h2>募集要項</h2>
This is not a role where you simply take over an existing codebase or work within a narrowly defined technical area.
You will have the opportunity to own the product lifecycle end-to-end—from understanding business requirements and defining specifications to architecture, implementation, deployment, and operations.
Our product covers the entire workflow from:
Ordering Design Payment Manufacturing Logistics
You will work across these areas and help determine how the system should be designed as we scale globally.
Because our current product was initially developed during the MVP phase with external development partners, you will also have the opportunity to review, redesign, and rebuild existing components when necessary.

<li>Establish engineering guardrails such as typing, testing, code review, and development standards.</li>
</ul>
Product &amp; Business Collaboration
