Job description

We’re seeking a visionary individual to lead at the strategic level, shaping the future of Defence’s digital landscape. This is a unique opportunity to influence technical direction across complex, large-scale programmes that have real-world impact.

In this role, you’ll be the driving force behind defining and embedding architectural strategy, ensuring it’s not only well-crafted but consistently delivered.

Responsibilities

As Principal Architect, you will:

  • Serve as a Service Assessor, evaluating internal and cross-government services to ensure compliance with the service standard and alignment with architectural principles.
  • Promote reuse and scalability across Defence, driving integration by default and reducing duplicate technologies to support sustainability and value for money.
  • Lead and inspire a team of Technical Architects to deliver high-quality outputs aligned with strategic priorities.

  • Adaptability and resilience, thriving in uncertainty, managing shifting priorities, and guiding others through ambiguity to deliver at pace.
  • Breadth of technical knowledge, enabling you to advise and challenge teams to find the best solutions for Defence.
