By integrating a vast catalog of components with a world-class digital manufacturing platform, MISUMI Americas empowers engineers and procurement teams to accelerate innovation across the entire product lifecycle. With operations in the San Francisco Bay Area and Chicago, the company serves as a vital partner for the most innovative companies in the Americas.

Impact in this Role: 
MISUMI Americas is bringing together MISUMI and Fictiv to build the future of manufacturing — combining standard, configurable, and custom parts into one powerful platform for engineers and manufacturers. We’re creating a faster, smarter, AI-enabled way to go from design to production, backed by global scale, deep supply chain expertise, and a culture that moves with startup speed. For builders, problem-solvers, and people who want to make a real impact, this is a rare opportunity to help transform how the world makes things.

Areas of Responsibility: Essential Functions

  • Technical Expertise — Write clean, well-tested code across the full stack. Build highly available, business-critical services in AWS using Node.js and event-driven architectures. Translate complex requirements into reliable, maintainable solutions.
  • Delivery — Consistently ship high-quality, defect-free code with tests and documentation. Own your work end to end — from design through deployment — with minimal oversight. Hold yourself to a high bar on code quality and system reliability.
  • Collaboration — Partner closely with adjacent teams and stakeholders to clarify requirements and unblock progress. Communicate proactively on task status and project impact. Contribute actively to technical design reviews and serve as a resource other engineers can rely on.
  • Team Orientation — Show up for the team. Help debug production issues, clear blockers, and improve shared systems — even when the issue isn't yours. Model the collaborative engineering culture you want to work in.
  • Continuous Improvement — Stay curious. Explore new patterns and technologies, share what you learn, and apply it to raise the quality of what we build together. Contribute to our Quality Management System (QMS).
  • All employees are expected to maintain and contribute to the QMS.

Desired Traits: Distinguished skills, abilities, features, character, and quality.

  • 3–6 years of relevant full-stack engineering experience
  • Strong proficiency in Node.js, JavaScript/TypeScript, React, and Next.js
  • Hands-on experience with AWS services, including SQS, Lambda, EC2, RDS, API Gateway, CloudWatch, AWS File Transfer Family, and Amazon Bedrock
  • Demonstrated ability to develop, version, and maintain applications, microservices, and APIs with clean, maintainable, and efficient code
  • Commitment to quality through unit and integration testing (Jest required; Vitest a plus
  • Experience with both SQL and NoSQL databases
  • Proficiency with Datadog for monitoring, logging, and performance analysis
  • Experience deploying, scaling, and securing modern web applications on AWS and Vercel
  • Ability to analyze and understand existing applications across front-end and back-end layers, including reverse-engineering legacy or undocumented code
  • Hands-on experience with AI-assisted development tools — code generation, testing, debugging, and solution design — while upholding quality and development standards
  • Proven ability to take ownership of ambiguous tasks and projects, providing direction and driving them to completion
  • Strong organizational skills with the ability to manage multiple timelines and deliver on schedule
  • Experience with distributed systems, caching, and security fundamentals (OWASP Top 10) is a strong plus
  • .NET development experience is a plus

Compensation range for this role is $100,000 - $130,000 USD annually
