- MISUMI Americas builds the digital infrastructure behind how the world’s hardware gets designed and manufactured
- We’re looking for a Lead Cloud DevOps Engineer to take ownership of the AWS infrastructure that runs our multi-regional, global platform — someone who wants to be hands-on with CloudFormation and Node.js every day, not just architecting on a whiteboard
- This is a builder’s role. You’ll lead infrastructure projects end to end — architecture, implementation, debugging, optimization — while writing the Node.js tools and services that keep deployment, monitoring, and platform operations running smoothly
- You’ll work closely with engineering, security, and product teams to keep our systems reliable, secure, scalable, and cost-efficient as we grow
- Design, build, and maintain AWS infrastructure using CloudFormation as our primary Infrastructure-as-Code tool
- Own and evolve our AWS environments for high availability, scalability, failover, and security
- Lead infrastructure projects from planning through execution, mentoring and guiding a small team
- Build and maintain Node.js–based tools and services for automation, deployment workflows, monitoring, and platform operations
- Design, implement, and maintain CI/CD pipelines for infrastructure and application deployments
- Set up and manage logging, monitoring, and alerting across our AWS environments
- Perform infrastructure upgrades and improvements while minimizing downtime
- Troubleshoot and resolve complex production issues across infrastructure, applications, and CI/CD systems
- Drive initiatives that improve performance, reliability, security posture, and cloud cost efficiency
- Collaborate cross-functionally with engineering, security, and operations
- Maintain clear documentation of infrastructure, automation, and operational processes
- Contribute to and uphold MISUMI Americas’ Quality Management System (QMS)
