Role summary

MISUMI Americas is seeking a Senior Backend Engineer to join their team and help build and scale their cloud-based, AI-powered digital manufacturing platform. This role focuses on the costing, pricing, lead time, and DFM aspects of their instant quoting system, directly impacting revenue and customer trust. The engineer will design and develop highly available, scalable backend services using Node.js, AWS, and event-driven architectures, creating robust APIs (REST/GraphQL). A key aspect of the role involves leveraging AI coding agents for development and testing, while ensuring the correctness of AI-generated code. The position requires strong skills in backend engineering, distributed systems, testing, system design, and production reliability, with a commitment to code quality and collaboration.

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

Partner closely with product, frontend, and infrastructure teams to ship features that actually move the business

Contribute to technical design discussions and drive best practices across the team

Help shape how the team works with AI: sharing patterns, tooling, and lessons learned

Debug production issues and improve system reliability

Continuously improve code quality through testing, observability, and documentation

What You Bring

5 + years of backend engineering experience

Strong skills in Node.js, JavaScript/TypeScript

Experience building systems on AWS (SQS, Lambda, EC2, RDS, etc.)

Solid understanding of distributed systems and event-driven architectures

Experience designing and maintaining REST or GraphQL APIs

Familiarity with SQL and NoSQL databases

A commitment to writing unit and integration tests

Knowledge of system design, caching, and security best practices (OWASP Top 10)

Hands-on experience shipping production code with AI coding agents (e.g., Claude Code, Cursor, Copilot agent mode), with clear examples of where you had to step in, correct, or override them

Strong code review skills, applied just as rigorously to AI-generated changes

Must be a U.S. citizen or lawful permanent resident (green card holder)

Nice to have:

AWS certification

Experience with high-scale or business-critical systems

Experience with pricing, quoting, or other numerically sensitive business logic

Experience building agent workflows, custom tools, or MCP integrations for your team

How You Work

You take ownership and ship clean, maintainable, production-ready code

You treat AI as a force multiplier, not a substitute for understanding the system

You communicate clearly and collaborate across teams

You solve problems proactively, even outside your immediate scope

You enjoy mentoring others and raising the bar for engineering excellence

You stay curious and keep learning new technologies and patterns

Why MISUMI Americas?

Work on real-world problems impacting global supply chains

Join a fast-growing company at the intersection of AI, software, and manufacturing

Collaborate with teams building products used by top hardware innovators

Competitive compensation and benefits

Flexible, West Coast-friendly work environment

Minimal travel (0–10%)
