Lead Security Engineer Job Farmington Hills area,Michigan USA,IT/Tech

This is a hands-on security engineering job that covers the full range of a lead security engineer role across all of MISUMI Americas. You'll be the person who does a lot of the security day-to-day work: securing our infrastructure, running access audits, setting up controls, reviewing our systems and code, and helping investigate incidents. You'll also have a real say in the policies and priorities that shape how we handle security across the company
A good portion of your time will go to keeping our infrastructure secure. That spans both physical networking and cloud, and it means staying on top of IAM, security groups, permission policies, and application permissions so access to our systems is tight and scoped the way it should be
Threat detection and incident response at MISUMI Americas is handled by a group across multiple departments, and you'll be part of it. When something comes up, you'll help investigate, both hands-on and by helping coordinate the response. You will also be the escalation point for routine security issues that end up being more than expected or the existing teams can handle on their own
As Lead Security Engineer, you'll make security decisions and help us figure out which security projects matter most across MISUMI Americas' global operations. You'll be doing the audits, checks, and reviews, and you'll help shape our security policies and standards alongside security leadership
A big and growing part of the job is how we handle AI. You'll manage the way our AI tools are set up and help determine what's safe to turn on and what needs to be disabled. You'll also work closely with Information Security to contribute and maintain evidence for J-SOX, NIST 800-171, CMMC 2, and SOC 2 across a global business
Be the hands-on security lead across IT and engineering, making everyday security calls and acting as the main point of execution for security work
Look at security risk across the environment and help decide which security projects and initiatives to tackle first across MISUMI Americas' global operations
Help write, shape, and enforce our security policies, standards, and governance alongside security leadership
Serve as part of our threat detection and incident response group, a cross-departmental team, helping investigate incidents both hands-on and by coordinating the response
Act as the escalation point for the IT team, giving them direction, mitigations, or solutions when an issue is beyond the routine security task
Dig into root cause on the tougher problems and help put fixes in place so the same thing doesn’t keep coming back
Keep our infrastructure secure across both physical networking and cloud, from firewalls, segmentation, and wireless to the way our cloud accounts and workloads are set up and protected
Design and manage IAM at the infrastructure level, including roles, security groups, and permission policies, all scoped to least privilege
Review and tighten application permissions and access policies as the environment grows, and catch misconfigurations and permission drift before they turn into problems
Run user access audits and regular access reviews across our identity and application layers
Decide what user groups and roles we need to manage access to systems
Handle access as people join, move, and leave, and keep permissions in line with policy
Manage our enterprise AI tools such as Claude, keeping configurations, roles, and access up to date
Look at new AI capabilities one at a time (Claude for Chrome, for example) and make the call on whether to turn them on and what guardrails they need
Vet new AI integrations before they go live, including running automated scans and reviewing them by hand before any new local MCP server gets approved
Turn those AI…
