What makes this role different. OT security in pharmaceutical manufacturing is not IT security applied to different hardware. A control that is routine in IT can halt a production line or invalidate a GxP validation, and change design has to account for that from the start. You will need genuine IEC 62443 and Purdue model depth — IT security leadership alone does not transfer, and the interview will test this directly. Your team spans the US, UK and India, and you will also hold Workday line management for three architects whose day-to-day work sits in other domains.
Key responsibilities
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.
Basic Qualifications
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
Preferred Qualifications
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.
