Position Summary Job Purpose: Own the Network and Zero Trust domain as design authority for GSK. Zero Trust is a current Cyber Architecture and Solutions priority being built from the ground up rather than maintained, so this role is designing where GSK has no incumbent framework. A two-person domain: you and one Principal Architectyou and one Senior Principal Architect, with no engineering function of your own — Security Solution Engineering builds to your specifications and a managed service vendor operates the result. About the team. Security Architecture and Solution Engineering sets the target-state security architecture for GSK and builds the solutions that realise it. The function brings IT and OT architecture under single ownership for the first time, spanning Network and Zero Trust, Application Security, Platform Security, MDR and Detection Engineering, VM and Configuration Management, Data Security, and OT Security across a global manufacturing, laboratory and research estate. Architecture sets the standards and reference designs, Solution Engineering builds, tests and packages them, and a managed service vendor operates them. Architecture accountability never transfers: Cyber Architecture and Solutions designs and builds, the vendor runs. Twenty roles, with standards applying in more than 100 countries. What makes this role different. You are building a Zero Trust framework from nothing, not operating one someone else designed. This is a design authority role with a very small team: one Principal Architectvery small team: one Senior Principal Architect, no engineering function of your own — Solution Engineering builds what you specify and the vendor operates it. If you need a large team or direct control of implementation to be effective, you will find this frustrating. Expect to be asked what failed in a Zero Trust programme you ran, not just what you designed. Key responsibilities: This role will provide you the opportunity to lead key activities to progress your career. These responsibilities include some of the following: Act as design authority for Network and Zero Trust architecture across GSK. Own the Zero Trust policy framework: device trust, identity trust and application access policy.
