Sysadmins/⁠Senior Sysadmins at The Positive Internet Company

The company

Positive focuses on GNU/Linux and free software like very few other organisations do. From the company’s desktop machines through to complex computing clusters, as well as in significant parts of our networking stacks, our deep commitment to free software shines through. Can we interest you in a rare opportunity to work for a company with that dedication?

Positive Internet has been providing managed services and hosting based on free software for nearly 20 years. We have positions
available in our lively and friendly team providing support for a range of GNU/Linux systems running secure networked services for a
diverse range of clients including some of the globe’s biggest brands.

The roles

We have several positions open at this time and welcome applications from candidates ranging from enthusiastic amateurs to seasoned sysadmins.

Initial salaries range from £22000 for trainees to £65000 p/a for more experienced candidates. The starting salary will depend on experience and location as we have positions available in London and Cambridgeshire; Positive offers excellent prospects for career development.

All applicants should have experience in some aspects of GNU/Linux sysadmin, tuning the GLAMP stack – including configuring and maintaining MySQL and/or MariaDB, shell scripting, DevOps methodologies, configuring HA hardware, software and storage clusters. Experience with Debian is especially welcome.

Candidates for senior positions should have significant experience of high-availability platforms in heterogeneous environments, including configuring and maintaining private cloud stacks based on Xen and KVM virtualisation technologies and, ideally, hybrid AWS platforms, deploying with tools like Ansible and Puppet, configuring caching technologies like Varnish, and some experience in deep-configuration and securing of popular free application stacks, including Magento, WordPress and so forth. Ideally, senior candidates will also have experience of attaining and maintaining secure systems up to PCI Level 1 and ISO27001 standards.

Reporting to the Technical Team Manager and benefitting from the support of a small, lively, and talented team, we nonetheless expect you to work autonomously on a number of projects for the company and its clients, ranging from providing support and troubleshooting through configuring and tuning new private clouds to coordinating technical relationships with our key clients.


We can offer these positions in one of two locations: either working from our offices in Soho, the very heart of London’s West End (5
minutes’ walk from Oxford Circus and Piccadilly Circus tube stations) or in the NOC of our wholly-owned data centre in Cambridgeshire (by train, 14 minutes from Peterborough, 30 minutes from Cambridge).

Whilst you will generally work either in the London offices or Cambridgeshire data centre, we do offer some home-working
opportunities. You will join the Technical Team on-call rota which involves occasional weekend working remunerated separately.

Positive gives a good holiday allowance (25 days + bank holidays + goodwill days around Christmas/New Year), lots of training opportunities, funding to attend free software conferences such as FOSDEM and other technical training/conferences, company mobile phone, and the chance to work with some of the best free software experts in the business.


This position should interest anyone with a passion for working in a GNU/Linux-only environment with a team that shares your commitment to free software and technical solutions.
