What the job involves

• MISUMI Americas builds the digital infrastructure behind how the world’s hardware gets designed and manufactured

• 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)
