About The Position

The OT/IT Integration Security Architect will serve as a senior subject matter expert responsible for defining and executing secure integration strategies for mergers and acquisitions (M&A) across Thermo Fisher Scientific’s manufacturing, laboratory, and R&D environments. This role focuses on rapid assessment, risk mitigation, and the design of scalable, secure architectures that enable seamless integration of acquired OT and IT environments into the enterprise. Working across M&A, IT, OT, R&D, and business leadership teams, the Architect will assess acquired environments, define integration roadmaps, and ensure alignment with enterprise cyber security standards and regulatory requirements. This is a highly visible, fast-paced role requiring strong technical depth, architectural leadership, and the ability to influence stakeholders in dynamic and often ambiguous environments.

Requirements

• Extensive experience in OT cyber security architecture, IT security architecture, or integration architecture within industrial environments.
• Strong knowledge of industrial systems, ICS/SCADA technologies, and protocols (e.g., Modbus, OPC, Ethernet/IP, PROFINET).
• Proven experience designing segmentation strategies, DMZ architectures, and secure connectivity between OT and IT environments.
• Experience with enterprise identity platforms (e.g., Active Directory, Entra ID/Azure AD) and identity integration during M&A
• Experience leading or supporting M&A integrations, technical due diligence, or large-scale transformation initiatives.
• Deep understanding of cyber risks in OT environments and practical application of mitigation strategies.
• Experience working in fast-paced, high-ambiguity environments with competing priorities and aggressive timelines.
• Strong communication skills with the ability to present complex architectural concepts to executive and non-technical audiences.
• Demonstrated ability to influence stakeholders and drive alignment across global, matrixed organizations.
• Ability to operate both strategically and tactically, from high-level architecture design to hands-on assessment and guidance.
• Bachelor’s degree in Engineering, Computer Science, Cyber Security, or related field preferred.
• Strong familiarity with OT security standards such as ISA/IEC 62443 and NIST CSF.
• Expertise in network segmentation, zone/conduit architecture, and Zero Trust principles applied to OT/IT integration.
• Experience with OT security monitoring platforms and SIEM integration.
• Understanding of regulatory requirements impacting manufacturing, lab, and R&D environments (e.g., GxP, FDA).
• Experience with cloud, edge, and IIoT integration scenarios and associated security considerations.
• Familiarity with asset discovery and visibility tools in OT environments.
• Experience with threat modeling and risk-based security design for integrated environments.
• Ownership: Drive architecture and integration strategies for M&A activities with minimal oversight.
• Complexity: Operate independently in complex, high-pressure environments with evolving requirements.
• Leadership: Influence cross-functional teams and represent security architecture in executive discussions.
• Communication: Simplify complex technical risks and architectural decisions for diverse audiences.
• Adaptability: Respond effectively to changing priorities and incomplete information during integration efforts.
• Improvement Mindset: Continuously refine integration approaches based on lessons learned and emerging best practices.

Nice To Haves

• Relevant certifications (e.g., CISSP, CISM, GICSP, ISA/IEC 62443, CCSP) highly desirable.
• Equivalent work experience may substitute for formal education.
• Experience leveraging Generative AI to accelerate assessment, integration planning, or threat analysis is desirable.

Responsibilities

• Define and drive OT/IT integration security architecture strategies, standards, and roadmaps for M&A activities.
• Design secure integration architectures that align acquired environments with enterprise OT and IT security frameworks.
• Establish scalable patterns for repeatable and efficient integration of diverse manufacturing, lab, and R&D environments.
• Balance speed of integration with risk reduction, ensuring business continuity and operational resilience.
• Lead OT and IT cyber security assessments for acquisitions, including site evaluations and technical due diligence.
• Identify risks, gaps, and remediation priorities across acquired OT/ICS, lab, and IT environments.
• Develop integration strategies and phased roadmaps aligned to business timelines and risk tolerance.
• Provide actionable recommendations to leadership on integration sequencing, investment needs, and risk mitigation.
• Apply enterprise OT security standards and frameworks (e.g., ISA/IEC 62443, NIST) to integration activities.
• Design and implement segmentation strategies, including zone/conduit models and OT/IT DMZ architectures.
• Ensure integration of monitoring, detection, and response capabilities within acquired environments.
• Support development of security controls aligned with regulatory, quality, and compliance requirements (e.g., GxP).
• Bring deep understanding of industrial control systems (SCADA, DCS, PLCs), lab instrumentation, and manufacturing processes.
• Ensure secure integration of OT systems with enterprise IT platforms, including identity, logging, and monitoring systems.
• Evaluate and rationalize legacy technologies, balancing modernization with operational constraints.
• Ensure minimal disruption to manufacturing, lab, and R&D operations during integration activities.
• Partner with M&A, IT, OT, engineering, and site leadership teams to execute integration strategies.
• Act as a bridge between acquired entities and enterprise teams to align on security standards and expectations.
• Communicate risks, architectural decisions, and trade-offs clearly to technical and executive stakeholders.
• Influence stakeholders across a global, matrixed organization to drive consistent and secure integration outcomes.
• Develop reusable playbooks, templates, and standards for OT/IT integration in M&A scenarios.
• Stay current with emerging threats, technologies, and integration strategies relevant to OT and IT environments.
• Identify opportunities to improve speed, consistency, and security of future integrations.
• Leverage automation, analytics, and AI-driven capabilities to enhance integration and security processes.
• Travel Up to 50% travel to acquired sites globally to perform assessments, support integration, and engage stakeholders.
