Senior Linux System Administrator


We are a technology driven company of around 45 people in the sports betting sector. We're looking for a Senior Linux System Administrator to lead a small team to support the business.

Our technology stack includes:

  • Linux servers (primarily Ubuntu, some CentOS)
  • LXC containers
  • Zabbix monitoring/alerting
  • PostgreSQL
  • OpenVPN
  • VyOS and HPE networking
  • Linux and Windows desktops
  • Active Directory and FreeIPA
  • ZeroMQ and RabbitMQ
  • Google G Suite

The successful candidate will be able to demonstrate proficiency with:

  • Networking fundamentals, including diagnostics, routing, and firewalling
  • Linux server administration and troubleshooting
  • Linux virtualisation, ideally with LXC

Experience with other parts of our technology stack is advantageous but not essential. We are looking for the right person, rather than for a shopping list of skills. You need to bring a rigorous approach to the weakest of your technical areas in addition to playing to your natural strengths.

We're looking for someone that can muck in to support and troubleshoot anything and everything, to support the needs of the business. We want someone that can self start on project work but who is not afraid to approach in-depth troubleshooting across the full application stack.

The users you will be supporting are intelligent and friendly. Primarily they are the internal development, trading and quant teams.

You will have at least 4 years of Linux admin and networking experience. You will be comfortable at the command line and will be equally at home managing storage and filesystems as you are at configuring routing and firewalling.

Due to the nature of the role, there will be an element of out of hours support. The business operates whenever sport is being played worldwide, which may not coincide with UK working hours. However, problems are rare, and situations where infrastructure has failed to the point where it has needed out of hours support have been few and far between over the last 5 years.

To apply please send your CV and covering letter to jobs@mustardsystems.com
