The organisation works closely with a major healthcare institution and is currently reviewing the long-term structure of its IT function. This is an excellent opportunity for a hands-on IT and cybersecurity professional to take ownership of a broad, high-impact role during an important period of organisational development. The Role The IT and Security Lead will be the key point of contact for IT, digital and cybersecurity matters across the charity.
