You will lead 3rd party suppliers in the ongoing operation of our Datacentre networks and oversee the multitude of projects that deliver new capabilities to the Home Office. 

This role requires a strategic and collaborative mindset. You will work closely with multi-disciplinary teams, suppliers, and third-party providers to ensure our network infrastructure is designed and implemented with security, reliability, and performance at its core.

You define engineering best practice within the Home Office and inspire others to follow.  

You will own the technical operational relationships with suppliers and internal teams making sure Data Centre network services are delivered and aligned to industry best practice, regulatory and contractual requirements.

  • establishing standards and procedures across a service lifecycle including the development lifecycle and ensure that engineers adhere to this. You will manage resources to ensure that the networks integration function works effectively
  • providing authoritative advice and guidance on test planning and identify network improvements to determine standards and best practice

Like many organisations we need to maintain our services 24/7, therefore, on occasions there may be a requirement to work out of hours, for which you will be paid an additional allowance.
