Job Title
Lead Manufacturing Technology 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 strengthen the security, reliability, and scalability of 3M's manufacturing technology environments by designing secure OT architectures, engineering resilient infrastructure, and developing standardized industrial software and controls solutions. Your work will directly support critical production systems, improve consistency across manufacturing sites, reduce technical and cybersecurity risk, and enable secure modernization of legacy OT environments while maintaining operational continuity.

As a Lead Manufacturing Technology 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:

• Designing and Partnering with Security team to implement secure OT architectures, network segmentation, defense-in-depth controls, secure remote access, and technical remediation strategies for manufacturing environments
• Engineering resilient OT infrastructure solutions, including compute, virtualization, networking, backups, redundancy, power protection, and recovery capabilities that support critical production requirements
• Developing standardized industrial software architectures, reusable templates, libraries, naming conventions, and frameworks that can be deployed consistently across manufacturing sites
• Evaluating IoT and IIoT components, including embedded devices, controllers, gateways, firmware, communications protocols, authentication, encryption, interfaces, and update mechanisms
• Translating OT cybersecurity, engineering, and regulatory requirements into executable designs, validation methods, remediation strategies, and technical governance practices
• Mentoring technical teams and helping establish standards that improve consistency, reliability, and long-term sustainability across 3M's global manufacturing technology landscape

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 in Engineering, Automation, Computer Science, Information Technology, Cybersecurity, a Technical field (completed and verified prior to start)
• Professional Engineering or Advanced Technical Credentials - Professional Engineer license, advanced engineering credentials, advanced technical certifications, or equivalent demonstrated technical leadership in the design and delivery of complex industrial systems.
• Fifteen (15) years of experience designing, implementing, or supporting industrial controls, automation, OT systems, or manufacturing technology environments in a private, public, government or military environment
• Eight (8) years of experience with OT security architecture, network segmentation, secure remote access, industrial software platforms, controls engineering, or OT infrastructure resilience
• Eight (8) years experience leading technical initiatives across manufacturing, critical infrastructure, cybersecurity, engineering, automation, or industrial technology environments
• Current, valid Driver's License.

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

• Senior OT / Controls Engineering Experience - 15+ years of progressive experience designing, implementing, and supporting industrial controls, automation, and OT systems in complex manufacturing or critical-infrastructure environments.
• OT Security Engineering & Architecture - Demonstrated experience translating OT security requirements into implementable engineering standards, secure architectures, segmentation strategies, defense-in-depth controls, secure remote access, and technical remediation approaches while maintaining production availability.
• Industrial Software Architecture & Standardization - Advanced experience designing industrial software architectures and developing reusable templates, libraries, naming conventions, standards, and development frameworks for platforms such as Ignition or equivalent industrial application platforms.
• IoT / IIoT Component-Level Security & Engineering - Experience evaluating connected industrial devices at the component level, including controllers, gateways, embedded systems, firmware, communications protocols, authentication, encryption, interfaces, update mechanisms, and secure integration into OT environments.
• OT Infrastructure & Resilience Engineering - Experience engineering OT compute, virtualization, networking, backups, UPS and power protection, redundancy, recovery, and resilience solutions capable of supporting critical-line RTO/RPO requirements.
• OT Standards, Compliance & Technical Governance - Ability to translate OT cybersecurity, engineering, and regulatory requirements into executable designs, processes, validation methods, remediation strategies, and technical governance practices supporting critical-line compliance and requirements such as NIS2, MLPS, and TISAX.
