Advanced OT System Specialist

Collaborate with Innovative 3Mers Around the World

Choosing where to start and grow your career has a major impact on your professional and personal life, so it’s equally important you know that the company that you choose to work at, and its leaders, will support and guide you. With a wide variety of people, global locations, technologies and products, 3M is a place where you can collaborate with other curious, creative 3Mers.

This position provides an opportunity to transition from other private, public, government or military experience to a 3M career.

The Impact You’ll Make in this Role
In this role, you will help reduce operational risk across 3M’s manufacturing environments by identifying unintended connectivity, validating OT infrastructure, and uncovering unmanaged technologies that could create exposure between plant systems and broader company networks. Your work will strengthen site readiness, improve visibility into manufacturing technology environments, verify remediation effectiveness, and support repeatable technical validation practices that help protect operational continuity, system reliability, and 3M’s global manufacturing resilience.

As an Advanced OT System Specialist, you will have the opportunity to tap into your curiosity and collaborate with some of the most innovative people around the world. Here, you will make an impact by:

• Leading technical assessments across manufacturing sites to identify unintended connections between OT equipment, business networks, wireless networks, remote systems, and the internet
• Validating OT devices, infrastructure, remote-access tools, and configurations to identify conditions that may bypass established architecture or create unintended access pathways
• Performing site pre-assessment reviews that help field teams arrive with a targeted understanding of potential gaps and areas requiring investigation
• Verifying remediation actions to confirm identified connectivity and infrastructure gaps have been addressed and determine whether additional action is needed
• Establishing repeatable methods to improve visibility into unknown or unmanaged technologies, services, connections, and changes within manufacturing environments
• Conducting recurring technical reviews that help identify newly introduced risks and strengthen the security, reliability, and resilience of 3M’s global manufacturing operations
• Constructing and facilitating tabletop drills that validate operational response, escalation paths, roles and responsibilities, recovery processes, and site readiness

Your Skills and Expertise 

To set you up for success in this role from day one, 3M requires (at a minimum) the following qualifications:

• Bachelor’s degree or higher (completed and verified prior to start)
• Five (5) years of Cybersecurity and Information Assurance in a private, public, government or military environment
• Five (5) years of Offensive Security Experience in a private, public, government or military environment
• Current, valid Driver’s License.

Additional qualifications that could help you succeed even further in this role include:

• Advanced Technical Assessment Experience — Demonstrated ability to evaluate complex enterprise and manufacturing environments, identify unintended connectivity, technical weaknesses, and potential access pathways.
• OT / Critical Infrastructure Experience — Experience working with industrial, manufacturing, or other critical infrastructure environments where availability, operational continuity, and risk must be balanced.
• Network & Infrastructure Expertise — Strong technical knowledge of networking, firewalls, remote access, identity, endpoints, servers, wireless technologies, and internal/external connectivity.
• Technical Exposure & Validation Experience — Experience developing repeatable methods for evaluating external and internal systems, identifying gaps, validating corrective actions, and conducting recurring technical reviews.
• Tabletop Exercise Leadership — Experience developing, facilitating, and leading tabletop exercises that validate operational response, escalation paths, roles and responsibilities, recovery processes, and organizational readiness.
• Advanced Technical Credentials — Advanced industry certifications such as OSEE, OSEP, OSCP, CISSP, or equivalent, demonstrating deep hands-on technical assessment, systems, and advanced security expertise.
