About the job

The UK Security Operations (SecOps) team in Google Public Sector delivers, operates and secures private cloud services. We aim to provide the flexibility, reliability, and scalability of public cloud for customers with exceptionally high security requirements that can only be met in a private cloud environment. We deliver and operate these private cloud deployments for the most critical customers, helping scale, secure and maintain the deployment whilst working closely with Google product teams to continually improve our technology. This Principal Security Architect role is pivotal in supporting and guiding Google's public sector customers by acting as their executive, trusted security advisor.

As a Principal Security Architect, you will directly advise customers at all levels, from C‑suite to engineering, on security best practices, risk management, and compliance. You will be a key advisor and a primary point of contact for customer security strategy, translating technical concepts into clear, actionable recommendations. You will focus on building trusted relationships, fostering customer confidence, and ensuring their long‑term success and security on our cloud services.

In this role, you will be responsible for collaborating with and guiding customers on the development and implementation of comprehensive security architectures on Google's cloud platforms. This involves defining secure patterns, standards, and best practices that ensure their infrastructure, applications, and data are resilient against evolving threats. You will provide architectural leadership for customer initiatives, conducting thorough security reviews of customer designs, and identifying opportunities to improve their security posture.

Responsibilities

• Act as the primary trusted security advisor for key public sector customers, providing consultation on security architecture, risk management, and compliance.
• Build and maintain collaborative relationships with customer stakeholders (from technical teams to C‑level), understanding their unique security needs and effectively communicating Google's security capabilities and best practices.
• Lead the design and review of secure solutions for customers on cloud platforms, ensuring secure configurations and demonstrating compliance pathways. Foster a security‑aware culture within customer organisations, advocating security‑by‑design principles.
• Guide customers on security best practices, including embedding security into their CI/CD pipelines (DevSecOps) and adopting security automation.
• Guide customers in identifying, assessing, and mitigating cloud security risks specific to their environments and workloads. Translate security standards and regulations into practical, achievable implementation plans for customer architectures.
