Are you a Linux systems administrator who relishes the idea of working at all levels to provide high quality and responsive IT services to highly technical staff? Do you have an obsessive desire to implement and improve systems and services using configuration management and automation tools? Are you equally happy managing and debugging networks, cloud services, and access management systems? Role As a senior systems administrator at Semmle, you will work on a wide range of systems administration and development tasks within Semmle’s IT team based in central Oxford. You will play a leading role in the planning, design, development, operations and support of reliable and efficient services to internal and external customers – investigating specialist technologies when required. Where necessary, you’ll be able to work independently, in addition to helping to build a collaborative team-based approach to IT delivery. You will participate in a support desk role providing support to Semmle staff at all levels, using collaborative tools such as ticketing systems, wikis and IRC, and participate in occasional maintenance work. You’ll out-of-hours work on services hosted on Debian GNU/Linux, as well as Windows and OSX.
