Senior Principal Architect - Security Architecture & Solution Engineering - Shared Engineering

Overview

Lead the shared security engineering build function that turns architecture specifications across IT and OT security domains into built, tested and handover-ready solutions, leading seven engineers across four squads.

What you'll do

• Own build, test and packaging across all security domains, leading seven engineers across four squads.
• Own the quality of vendor handover packages so a managed service can operate what was built without Cyber Architecture and Solutions present.
• Build to the specifications the architecture domains set, escalating design problems rather than reinterpreting them.
• Own acceptance against the architecture specification and the operational readiness criteria, and refuse handover where test evidence does not cover the failure modes the design depends on.
• Own engineering standards, reusable build components and the solution testing playbook library.
• Arbitrate when two domain Directors both want the same squad in the same sprint, and hold the line on test coverage when a programme date is at risk.
• Lead and develop seven engineers, including three squad leads, an engineering excellence lead and the analyst and support roles.
• Own the configuration record standard the whole function builds to, sufficient to answer a GxP audit on who changed which control and under what change.
• Send back specifications that cannot be tested, with no stated success criteria, failure mode or rollback, rather than building to interpretation.
• Run vendor shadowing and reverse-shadowing through transition, and close the gaps their first 30 days expose back into the handover pack standard.
• Lead your team in using approved AI tools to improve productivity and ways of working, role-modelling responsible use and following GSK's Responsible AI, privacy and security requirements.
• Own hiring, performance management and succession across the four squads, and build the engineering bench the function will need as the vendor model matures.

What you'll need

• 15+ years in security engineering, including leading technical teams across geographies.
• Experience leading a security engineering team turning architecture into built, tested capability, with four squads matching the Product Management domains one for one, each working in parallel with its domain product owner on use cases, roadmap and build priorities.
• Experience with standard builds through automated pipelines, including build documentation, test evidence, configuration baselines and operational playbooks, plus a cross-domain security automation programme.
• Experience with vendor handover packs and operational-readiness sign-off before managed service takeover, and proof-of-value builds informing architecture and investment decisions.
• Experience engineering AI-enabled security solutions, including the build, test and documentation standards that agentic automation is held to.
• Bachelor's degree in a relevant discipline, or equivalent professional experience.

Nice to have

• Infrastructure as code, CI/CD and configuration management tooling (Terraform, Ansible, GitHub Actions).
• Security certification such as CISSP, or vendor certifications across SIEM, EDR or network security platforms.
• Regulated industry experience, including GxP.
• Experience running release management for security tooling where a failed EDR or proxy change has blast radius across more than 100 countries.
• Experience standing up a shared security engineering function from scratch, including the first build standards and the first vendor handover pack.

Details

• Location: Bengaluru, Luxor North Tower.
• Typical tools and technologies include build and test automation, infrastructure as code using Terraform and Ansible, CI/CD pipelines, containerisation and Kubernetes, security tooling integration and API automation, Python and PowerShell, and ServiceNow.
