As the Principal Technical Architect, you’ll:

  • help enable the reuse of patterns, tools, and components across Cabinet Office and wider government
  • forge close working relationships across the cross-government technical architecture community to identify opportunities for reuse of existing services and components
  • contribute to new technology patterns, standards and guidance for implementation by government

It’s essential that you have demonstrable experience of:

  • security architecture within enterprise IT technology systems, with strong experience in designing a secured enterprise IT architecture and applying security governance
  • architecture experience with common public cloud platforms (particularly Microsoft Azure & Amazon Web Services) and related technologies (for example, elastic scaling, platform as a service and networking architecture in the cloud)
  • communicating highly technical matters to non-technical colleagues across the department
  • working in dynamic fast paced agile environments, collaboratively and openly with others
  • building enterprise IT services using user-centred approaches, advocating for the best decision making based on end-user experience, IT administrator/operator experience, cost, technology and cybersecurity risks
  • leading and influencing highly specialised technical teams, including steering decision making and improving how those decisions are made and technical systems are operated
  • developing or directly influencing enterprise IT strategies supported by user research, balancing technology against cost, user experience, operational/support experience and strategic goals

It’s desirable that you have experience of or familiarity with:

  • Technology Code of Practice and the Digital Service Standard and how these apply to enterprise IT within an organisation and cross-government
  • security architecture for technology systems and services
  • UK government cybersecurity standards
  • Applied information governance within enterprise IT systems, such as records management, data protection and privacy
  • Information assurance governance processes as they apply to information held by IT systems, or assurance of the IT systems themselves
  • building IT services that scale efficiently
  • working with senior management to define directorate priorities based on medium-long term strategies and organisational direction, including developing forecasted costings and businesses cases for new technology programmes


  • Communication skills: you can listen to the needs of technical and business stakeholders, interpret them and advocate on behalf of IT users. You are skilled at proactive and reactive communication.
  • Governance: you can evolve and define governance. You can take responsibility for collaborating and supporting other staff in wider governance. You know how to assure services delivered by technical architects across sets of services.
  • Making and guiding decisions: you can make decisions characterised by managed levels of risk and complexity. You can recommend decisions as risk and complexity increase. You can resolve technical disputes between wider peers and indirect stakeholders, taking into account all views and opinions.
  • Strategy: you can apply strategy, using patterns, standards, policies, roadmaps and vision statements. You can challenge strategies and feed into their development/iteration. You can provide guidance to others on how to interpret and implement strategies that have been set.
  • Turning business problems into technical design: you can design systems characterised by medium levels of risk, impact, and business or technical complexity. You can work across multiple services or a single large or complicated service.
  • Understanding the whole context: you understand trends and practices outside your team and how these will impact the work. You understand how your work fits into the broader strategy and historical context. You can consider the patterns and interactions on a larger scale.
