OT Security Architect

GSK is seeking an OT Security Architect to own OT security architecture across its global manufacturing, laboratory, and research estate. The successful candidate will lead a team of seven and be responsible for 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.

Key responsibilities include:

• Owning OT security architecture across the global manufacturing, laboratory, and research estate
• Leading IEC 62443 zone and conduit design and Purdue model network segmentation
• Designing safety system boundaries and constraints that follow from GxP validation
• Managing OT vulnerability architecture where standard IT patching cannot be applied
• Leading OT asset discovery architecture across sites with incomplete inventories
• Developing OT detection architecture for handoff to the Cyber Defence SOC
• Driving convergence of IT and OT security controls without importing IT assumptions that break production
• Leading a team of OT architects across the US, UK, and India
• Contributing to the Future Ready OT programme, GSK's multi-year effort to bring manufacturing and laboratory sites to a common OT security baseline

The ideal candidate will have 20+ years of experience in security architecture, including managing matrixed reports across geographies, with a domain focus on OT Security (OT, ICS, and IoT across manufacturing, laboratory, and research sites).

Basic qualifications include:

• Experience with OT network zone and conduit segmentation and OT monitoring integration using Claroty, Dragos, or Nozomi Networks
• Knowledge of OT vulnerability management where IT patching cannot be applied
• Experience leading an OT specialist team within GxP-validated manufacturing constraints
• Familiarity with applying AI and ML to OT security

Preferred qualifications include:

• Experience leading an OT transformation or Future Ready OT style programme at enterprise scale
• Knowledge of OT asset discovery architecture across sites with incomplete or unreliable inventories
• Familiarity with NIS2 scoping and reporting obligations for manufacturing sites
