Director - Security Architecture & Solution Engineering - OT Security

GSK remains committed to achieving bold commercial ambitions for the future. By 2031, we aim to deliver £40 billion in annual sales, leveraging our existing strong performance momentum to significantly increase our positive impact on the health of billions of patients globally. Our Ahead Together strategy is centred on early intervention to prevent and alter the course of disease, thereby protecting people and supporting healthcare systems.

Our diverse portfolio consists of vaccines, specialty medicines, and general medicines.

Through continuous innovation and a dedicated focus on scientific and technical excellence, we strive to develop and launch new, groundbreaking treatments that address critical health challenges.

Domain focus: OT Security (OT, ICS and IoT across manufacturing, laboratory and research sites); domain authority aligned to IEC 62443 and the Purdue Model.

Own OT Security architecture across GSK's global manufacturing, laboratory and research estate, leading a team of seven. You own IEC 62443 zone and conduit design, Purdue model segmentation, safety system boundaries, OT vulnerability and detection architecture, and the convergence of IT and OT security controls in a GxP-validated environment.

This role will provide you the opportunity to lead key activities to progress your career. These responsibilities include some of the following:

• →Own OT security architecture across the global manufacturing, laboratory and research estate.

• →Own IEC 62443 zone and conduit design and Purdue model network segmentation.

• →Own safety system boundary design and the constraints that follow from GxP validation.

• →Own OT vulnerability management architecture where standard IT patching cannot be applied, including compensating control design.

• →Own OT asset discovery architecture across sites with incomplete inventories.

• →Own OT detection architecture for handoff to the Cyber Defence SOC, which operates it.

• →Drive convergence of IT and OT security controls without importing IT assumptions that break production.

• →Lead four OT architects across the US, UK and India, plus Workday line management for three architects whose functional work sits in other domains — an administrative rather than a technical responsibility.

• →Lead the OT architecture contribution to the Future Ready OT programme, GSK's multi-year effort to bring manufacturing and laboratory sites to a common OT security baseline.

• →Assure vendor handover for OT tooling and retain architecture accountability.

• →Lead your team in using approved AI tools to improve productivity and ways of working, role-modelling responsible use and follow GSK's Responsible AI, privacy and security requirements.

• →Evaluate and select OT security tooling against the architecture model, and own the cost and value of the OT security estate across the site portfolio.

• 20+ years in security architecture, including managing matrixed reports across geographies — domain focus: OT Security (OT, ICS and IoT across manufacturing, laboratory and research sites); domain authority aligned to IEC 62443 and the Purdue Model

• OT network zone and conduit segmentation and OT monitoring integration using Claroty, Dragos or Nozomi Networks

• OT vulnerability management where IT patching cannot be applied — compensating controls, automated asset discovery and risk posture reporting — and OT detection patterns and playbooks for the SOC and vendor

• Leading an OT specialist team within GxP-validated manufacturing constraints, where a routine IT control can halt production

• Applying AI and ML to OT security — anomaly detection in OT networks, AI-assisted asset discovery and secure adoption of AI in manufacturing

• Leading an OT transformation or Future Ready OT style programme at enterprise scale

• OT asset discovery architecture across sites with incomplete or unreliable inventories

• NIS2 scoping and reporting obligations for manufacturing sites in scope, and the evidence a competent authority expects.

• OT risk posture reporting to executive leadership, including automated dashboards, and direct engagement with site engineering and operations teams

• Partnering with Cyber Defence on OT threat exposure management and OT SOC handoffs
• Qualifications: Bachelor's degree in a relevant discipline, or equivalent professional experience.
• Typical tools and technologies: IEC 62443 zone and conduit design, Purdue model segmentation, OT monitoring platforms including Claroty, Dragos and Nozomi Networks, unidirectional gateways and data diodes, ICS, SCADA and PLC security patterns, OT asset discovery, safety instrumented system boundaries, OT vulnerability management and compensating controls, GxP-validated change control.
