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.

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

• 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

• 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)

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

• AWS certification

• Experience with high-scale or business-critical systems

• How You Work

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

• 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%)
