About the role

As a Senior Infrastructure Engineer, you'll play a central role in shaping, operating, and maintaining our predominantly Microsoft cloud environment, keeping it strong, secure, and ready for what comes next. Reporting to the Infrastructure Services Manager, you'll support, maintain, and enhance our enterprise infrastructure across Azure cloud, Microsoft 365, identity, endpoint, network, and core platform services.

You'll lead on complex incidents, drive root-cause analysis, and bring the kind of calm, expert thinking that keeps services running and colleagues confident. This is a hands-on, cloud-first role with real scope to influence how we design, govern, and optimise cloud services and our infrastructure for the long term. This role would particularly suit someone who has moved beyond traditional, on-prem infrastructure into operational Azure and Microsoft 365 engineering and is confident owning cloud platforms end-to-end.

• This role aligns primarily to SFIA Level 5 across the IT Infrastructure Operations (ITOP), Infrastructure Architecture (INAN), IT Operations (OPST), Systems Integration (SINT), and Network Engineering (RFEN) skill areas, with additional contribution from related SFIA capabilities where appropriate. Responsibilities of this role will involve:
  • Support, maintain and enhance enterprise infrastructure across Azure cloud, identity, endpoint, network and core platform services.
  • Design, implement and operate secure, resilient and scalable infrastructure solutions in hybrid environments.
  • Lead complex incident investigations, drive timely resolution and conduct root-cause analysis to prevent further occurrences.
  • Produce and maintain high-quality technical documentation, operational runbooks and service procedures to support delivery.
  • Manage and optimise cloud platforms and productivity services in a live production environment.
  • Apply Azure Well-Architected Framework principles to guide design, performance and operational decisions.

  • Embed secure design principles and support vulnerability management activities across infrastructure services.
  • Work closely with the Security team to operate within established security frameworks, policies and compliance requirements.
  • Lead on the application of modern identity protection approaches such as MFA, privileged access controls and conditional access.
  • Work within formal IT service management processes, including incident, problem, change and configuration management.
  • Maintain accurate configuration and asset data in line with CMDB and lifecycle management principles.
  • Collaborate with suppliers and managed services partners to ensure service quality, performance and accountability.
  • Build strong relationships with internal stakeholders, delivery teams and 3rd party suppliers.
  • Influence decisions through expertise, evidence, clear reasoning and trusted technical advice.
  • Contribute positively to the team culture, supporting colleagues to achieve our shared objectives.
  • Commit to continuous learning and maintain technical skills and knowledge up to date.
