Job Opportunities


Senior Developer (Networking) x2

The Network Systems team at University Information Services (UIS) has an opportunity for two people to join the team as Software Developers in Networking.

Network Systems is responsible for designing, building, operating, and supporting the University's backbone data network, internet connections, data centre network, and many departmental networks.

These posts are for Senior Developers (Networking), working under the Lead Engineer (Network Systems). The Development part of the Network Systems team is responsible for the associated software systems which support these services.

Software-Defined Networking (SDN) is a major growth area within Network Systems. The University is experiencing a shift of the network from a traditional design towards a more converged, integrated solution. This involves moving from manual configuration to driving centralised systems via APIs, and the provision of interfaces (both end user web and machine API) to departmental IT staff and end users. Meanwhile, the University is increasingly taking advantage of public cloud offerings, and improving infrastructure to enable these changes. The Network Systems Software Developers will be instrumental in supporting this work.

The team undertakes a broad spectrum of activities, and you should expect to work in several different areas. You are also encouraged to specialise in areas of particular personal interest. This position is usually based at the University's West Cambridge Site. Currently, however, you'll be expected to work remotely. Core hours are typically between 9 to 5, Monday to Friday, but this can be reasonably adjusted depending on your needs.

You will be responsible for:

  • Working with the Managing Engineer (Network Systems) to determine priorities.
  • Working as part of the Network Systems Development Team to carry out software development and system administration activities.
  • Ensuring your technical skills are kept up-to-date and relevant, with support from the University.

You will have previous experience with:

  • Linux system administration (ideally Debian-based).
  • Scripting using languages such as bash, Python or Perl.
  • Web development.
  • Software development and testing practices and processes, including debugging, administration, and automation.
  • Version control and code review systems such as git, including remote repositories such as GitHub or GitLab.
  • Network fundamentals such as: switches, routing, VLANs, DHCP, DNS, IP addresses, IPsec VPNs, etc.

The following skills / knowledge would also be useful:

  • Systems integration.
  • Modern software development, deployment and system administration tools and practices.
  • Programming in several languages including Python.
  • Design, administration and use of SQL databases (mainly PostgreSQL).
  • Modern web development, both frontend (including Javascript) and backend (preferably Django).
  • Write, maintain and use RESTful APIs.
  • Familiarity with internet standards and RFCs.
  • Experience with network middleware applications such as ISC BIND, ISC DHCP, FreeRADIUS and similar.
  • Use of virtualisation, containerisation, and public cloud such as AWS and GCP.
