About us

Our vision is a world where patients access healthcare wherever and whenever they need it. We believe that patients should be able to consult with a doctor or pharmacist whenever they need and that access to healthcare should be on-demand and at the patient’s convenience. We’re leading the way in providing expert, safe, online healthcare.

Role Purpose

We are seeking an ambitious and experienced systems administrator who is also keen to get some exposure to team leading and to grow their level of responsibility.

As a key player within the organization, you will be part of a small team supporting various systems and projects across a large infrastructure, including on-premises, hosted DC and cloud. Your primary role will be to support and develop existing Linux and Windows-based systems and applications. We use a GCP infrastructure, so you’ll need to be familiar with cloud solutions which will become increasingly important to the business in the months ahead.

As our business and team is growing, there is an opportunity for the successful candidate to occasionally deputize for the Head of IT, giving them an opportunity to develop their leadership skills and to contribute towards the future design and evolution of our infrastructure.
