Infrastructure Architect

Infrastructure Architect (Networking) | Outside IR35 | Remote

We're supporting a client looking for an experienced Infrastructure Architect to deliver the design of a resilient contingency hosting environment. This is a hands-on architecture role where you'll define an interim infrastructure solution that ensures business continuity while a wider cloud migration programme progresses.

The successful consultant will be responsible for producing end-to-end technical designs spanning infrastructure, networking, security and operational processes, with a particular focus on designing a robust and secure environment that can be implemented at short notice if required.

The Role

Working alongside technical and delivery teams, you'll lead the architecture of a temporary hosting platform, ensuring all infrastructure components integrate effectively and can support critical services. Strong networking expertise will be central to the role, alongside the ability to produce clear, high-quality technical documentation and architecture artefacts.

Key Responsibilities

  • Produce end-to-end infrastructure architecture and technical design documentation.
  • Design resilient infrastructure, network and security solutions for a contingency hosting environment.
  • Define operational models, support processes and implementation approaches.
  • Collaborate with technical stakeholders to validate designs and ensure alignment across infrastructure domains.
  • Identify technical risks and recommend pragmatic mitigation strategies.
  • Provide architectural guidance throughout the design phase.

Essential

  • Proven experience working as an Infrastructure Architect on complex IT programmes.
  • Strong networking architecture experience, including enterprise network design and connectivity.
  • Broad infrastructure knowledge across compute, storage, virtualisation and enterprise platforms.
  • Experience designing secure, resilient and highly available infrastructure environments.
  • Strong understanding of infrastructure security principles and operational support models.
  • Ability to produce detailed technical architecture documentation and communicate designs to both technical and non-technical stakeholders.

Desirable

  • Experience designing contingency, disaster recovery or business continuity environments.
  • Exposure to cloud migration programmes, particularly AWS.
  • Knowledge of hybrid infrastructure and transitional hosting environments.
  • Familiarity with enterprise architecture frameworks or recognised architecture methodologies.
