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.

Personal specification

We are looking for an ambitious and highly motivated person who can work in a dynamic environment. The successful candidate will be able to demonstrate that they have the drive and motivation to not only take on the systems administrator role, but to learn from the Head of IT and grow their experience of planning, design and management.

You should be a good a communicator and have pro-active approach to your work. Ideally you will be able to demonstrate some past exposure to management either as a team leader, line manager or having some project management experience.

You will be reliable and be able to deliver on your own tasks to a high level of quality, but you are also a team player and will do whatever you can to help the team achieve its goals.

The company is working in a hybrid model and so you will be supporting systems running in the office, but also in remote-hosted systems.

Occasionally you need to be ready to work after working hours including weekends (planned work or resolving production issues).
