Job Description
About the Digital and Data Team
Government Digital and Data is a community of experts leading digital transformation in government, creating more efficient services that have a meaningful impact on people's lives.

The Prime Minister has set out his vision for one in ten civil servants to work in tech and digital roles within the next five years as part of the blueprint for modern digital government.

The Digital and Data Team's mission is to provide GLD with an IT environment that's 'fit for the future'. That means updating many of our older systems and processes. Using an agile, user-centred approach, we develop and improve our products and services in collaboration with the people who will use them. We consider sustainability, environmental impact and innovative ways to improve our staff's experience at work.

The potential to shape our society's future is enormous and our purpose is to ensure the profession is equipped and inspired to deliver real, meaningful change for users; to do the work of transformation that makes government work better for everyone.

About The Role
In GLD our Lead Security Architects are responsible for ensuring the secure design and development of solutions across the department. They work closely with stakeholders throughout GLD to understand and meet security requirements in projects, ensuring that design standards are consistently applied during delivery.

This is a challenging yet rewarding role, focused on implementing cybersecurity controls across GLD's digital infrastructure, which spans multiple office locations across England.

GLD takes information security seriously, protecting the confidentiality, integrity, and availability of all data processed on its digital systems. As part of the Digital and Data team, you will provide assurance that cybersecurity best practices are applied consistently across GLD systems, acting as a subject matter expert on cyber risk and secure architecture.

You will provide secure design and technical assurance for digital solutions, ensuring alignment with GLD's architecture standards, risk appetite, and security best practices. You will identify, assess, and manage cybersecurity risks throughout project delivery, embedding security in all technical design decisions.

The role also involves delivering practical, hands-on support for cloud, network, and application security — particularly within Microsoft environments — and leading or contributing to cybersecurity governance and assurance forums, including business continuity and disaster recovery planning.

Collaboration is essential: you'll work with internal and external stakeholders, including other government departments, to maintain trust, transparency, and alignment on security matters. You'll also develop and maintain information security policies, overseeing penetration testing and vulnerability management activities to drive continuous improvement.
