Job Description
You will provide senior technical leadership for DEFRA’s End User Infrastructure estate, covering devices, endpoints, operating systems, application delivery, and modern workplace platforms across a predominantly Microsoft-based environment.
You will lead the architecture for complex and high‑risk services and change initiatives, defining domain standards, patterns, and roadmaps aligned to enterprise strategy, security requirements, and cross‑government standards. This includes operating across a mixed estate of modern platforms and legacy technologies, ensuring continuity of user services as the organisation transitions away from legacy delivery models.
Working Across Multidisciplinary Teams, You Will:
- Lead and assure technical designs and architectural decision‑making, particularly where services operate across device, operating system, and application runtime boundaries
- Guide teams and suppliers to deliver coherent, secure, operable, and value‑for‑money solutions across both modern and legacy environments
- Identify and manage architectural risks across multiple services, including those arising from legacy platforms, dependencies, and unclear ownership
- Communicate complex technical issues clearly to both technical and non‑technical stakeholders, particularly where user experience is impacted by cross‑domain dependencies
- Support and develop architectural capability through mentoring and collaboration
This role suits an experienced Technical Architect who can balance strategic thinking with hands‑on design leadership in a complex organisational environment, including operating in situations where technology, ownership, and dependencies are not always fully defined.
You will provide senior technical leadership for DEFRA’s End User Infrastructure estate, covering devices, endpoints, operating systems, application delivery, and modern workplace platforms across a predominantly Microsoft-based environment.
Responsibilities
The post holder will be expected to:
- Define and maintain the domain architecture for End User Infrastructure, including principles, patterns, standards, transition states, and roadmaps for modernisation across device, operating system, and application delivery layers
- Lead the technical design of high-impact and high-complexity EUI services and changes, justifying and communicating design decisions clearly, including decisions required to support legacy application behaviour
- Guide and assure the work of other architects, delivery teams, and suppliers, ensuring designs fit the broader strategy for government and Defra while remaining operable for end users
- Identify and manage architectural risks affecting multiple teams or domains, including risks associated with legacy platforms, cross-domain dependencies, and transitional states
- Provide leadership within the architecture community, including mentoring, coaching, and setting expectations for architectural quality in the EUI domain
Skills And Experience
- Significant experience of complex IT programme and service architecture in infrastructure and end user domains, including dependency management and multi-supplier delivery in environments where services span devices, operating systems, and application delivery
- Strong hands-on expertise in one or more relevant technology areas, such as endpoint management, end user devices, operating system deployment, enterprise application delivery, digital workplace platforms, or identity-related client technologies, combined with a broad understanding of adjacent infrastructure domains
- Experience working within a predominantly Microsoft-based environment, including Windows operating systems, Microsoft Office estates (including legacy, non‑Microsoft 365 versions), and Azure-based workplace platforms
- Experience supporting and designing for legacy application environments, including applications that have been centralised into virtual platforms (e.g. Citrix) due to compatibility or sustainability constraints
- Experience defining and maintaining domain standards, principles, patterns, and roadmaps, including transitional architectures that support migration away from legacy platforms (e.g. Citrix) towards modern alternatives such as Azure Virtual Desktop or other DaaS solutions
- Experience making architectural decisions on application delivery models, including determining whether services are best delivered via local installation (e.g. Company Portal), virtualised environments, or hybrid approaches
- Experience of architectural assurance, supplier challenge, options analysis, and evidence-based decision-making in a complex organisational environment
- Experience of working with security, operational, service, commercial, and delivery stakeholders to shape coherent end-to-end designs
- Strong understanding of secure-by-design approaches, government security expectations, and the operational realities of live service change
- Experience of mentoring, coaching, and leading other architects or technical specialists through influence rather than line management
