Build the Future of Manufacturing

Manufacturing is a $13 trillion industry, and most of it is still held together by spreadsheets, phone calls, and fax machines. MISUMI Americas is rewriting that.

We've been building a cloud-based, AI-powered digital manufacturing platform that takes companies from prototype to production faster than the industry thought possible. Our platform pairs intelligent software with a global network of vetted manufacturing partners, powering innovation across electric vehicles, robotics, and next-generation consumer products.

We're scaling fast, and we're looking for engineers who'd rather untangle hard, real-world problems than push pixels on a toy app.

You'll join the team that owns costing, pricing, lead time, and DFM (design for manufacturability) for our instant quoting platform.  When a customer uploads a part, our systems decide what it costs, when it ships, and whether it can be made.  Accuracy matters; our output directly drives revenue and customer trust.

We build with AI agents as a core part of how we work.  We're looking for strong engineers who use agents to plan, implement, and test faster, and who have the judgment to know when the output is wrong.

What You'll Do

As a Senior Backend Engineer, you'll help build and scale the systems running our global manufacturing ecosystem:

• Design and develop highly available, scalable backend services in AWS
• Build and maintain event-driven, asynchronous systems using Node.js
• Create robust APIs (REST / GraphQL) powering customer-facing and internal tools
• Use AI coding agents to take features from design through implementation and testing, while owning the correctness of every change
• Write specs, tests, and repo context that make agent-driven development reliable in a large, established codebase
