• Act as the hands-on security lead across IT and engineering, and the main point of execution for security work
• Help decide which security projects and initiatives to tackle first across MISUMI Americas' global operations
• Help write, shape, and enforce security policies, standards, and governance alongside security leadership

• Serve on our cross-departmental threat detection and incident response team, investigating incidents hands-on and helping coordinate the response
• Act as the escalation point for IT, providing direction, mitigations, or solutions when an issue goes beyond routine
• Dig into root cause on tougher problems and put fixes in place so they don't recur

• Keep infrastructure secure across physical networking and cloud — firewalls, segmentation, wireless, and cloud account/workload configuration
• Design and manage IAM at the infrastructure level: roles, security groups, and permission policies scoped to least privilege
• Review and tighten application permissions and access policies as the environment grows; catch misconfigurations and permission drift early

• Run user access audits and regular access reviews across identity and application layers
• Determine what user groups and roles are needed to manage system access
• Handle access changes as people join, move, and leave, keeping permissions aligned with policy

• Manage enterprise AI tools such as Claude, keeping configurations, roles, and access current
• Evaluate new AI capabilities (e.g., Claude for Chrome) and decide whether to enable them and what guardrails they need
• Vet new AI integrations before launch, including automated scans and manual review of any new local MCP server
• Turn AI security decisions into reusable policies and practices

• Review systems for security issues, including running automated scans
• Vet third-party and open-source components before adoption
• Partner with engineering to build security into how we ship software and infrastructure

• Gather and maintain audit evidence for J-SOX, NIST 800-171, CMMC 2.0, and SOC 2
• Run recurring compliance checks and validate controls across our global footprint
• Map controls and evidence to audit requirements and support audits start to finish, with a focus on evidence and remediation

• Turn manual security work into documented practices, runbooks, and repeatable processes
• Automate access reviews, monitoring, alerting, and reporting
• Keep security documentation and the internal knowledge base current

• Senior-level, hands-on expertise across identity and access management, infrastructure/cloud security, governance and compliance, incident response, application/integration security, and AI/LLM security
• Hands-on incident investigation experience and the judgment to serve as an escalation point on user-facing threats like phishing and spam
• Strong experience securing infrastructure across networking and cloud — firewalls and segmentation on the network side; IAM, security groups, permission policies, and application permissions on the cloud side
• Cloud security experience (AWS, Azure, or similar) and comfort designing roles/RBAC in platforms like Microsoft Entra ID, Okta, or AWS IAM
• Familiarity with security monitoring and detection tools sufficient to support investigations
• Real experience running user access audits, access reviews, and compliance checks
• Experience supporting audit/compliance programs such as SOC 2, NIST 800-53/800-171, CMMC 2.0, and J-SOX, including evidence gathering and control validation
• Solid application security skills: automation tooling, secure code review, and secure integration practices
• Confidence to make independent security decisions and sort competing priorities
• Working understanding of AI/LLM security — administering AI tools, weighing new capabilities for risk, and evaluating integrations like MCP servers
• A habit of converting manual security work into repeatable process and automation
• Clear communication and the ability to work across a distributed, multi-site, global organization
