About the Role
We're looking for a hands-on Lead Security Engineer to own the full range of security engineering work across MISUMI Americas. You'll secure our infrastructure, run access audits, build and enforce controls, review our systems and code, and help investigate incidents — and you'll have a real voice in the policies and priorities that shape how we handle security company-wide.
A big part of the job is infrastructure: both physical networking and cloud. You'll keep IAM, security groups, permission policies, and application permissions tightly scoped to least privilege. You'll also sit on our cross-departmental threat detection and incident response group, and act as the escalation point when a routine security issue turns into something bigger than the IT team can handle alone.
You'll help decide which security projects matter most across our global operations, run the audits and reviews that back that up, and help shape security policy and standards alongside security leadership. A growing part of the role is AI: you'll manage how our AI tools (including Claude) are configured, decide what new AI capabilities are safe to turn on, and vet integrations — including reviewing new MCP servers — before they go live. You'll also work with Information Security to build and maintain evidence for J-SOX, NIST 800-171, CMMC 2.0, and SOC 2 across a global business.
What You'll Do
Security Decisions & Prioritization
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
Incident Response & Escalation
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
Infrastructure Security
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
Identity, Access & User Audits
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
AI Security
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…
