Job Description

This hybrid role offers a great balance of home and office working. You’ll join your colleagues in your local office at least 2 days a week.

As the UK’s largest fibre-only network, and its only proven wholesale challenger, we’re busy setting new standards for what digital infrastructure can and should be.

Designed from scratch for the internet, our network is greener, more reliable and ready for the future. The products we provide over it not only lead the market on speed, value and service, they help businesses to innovate, provide entire communities with a better foundation for their digital lives and support economic growth, locally and nationally.

What does that mean for you? The opportunity to make internet connections (and daily life) a whole lot better, for a lot of people!

Joining us as an IP Capacity Planner

As an IP Capacity Planner, you will be accountable for planning and delivering our active service portfolio, including system and network administration, and project management. You will work closely with Network Architects and Engineers to optimise network performance and ensure operational excellence. This role is crucial for driving a lean operating model through automation and AI.

You’ll receive a salary of up to £65,000, a performance related bonus, and a range of benefits to support you across your financial, physical and mental wellbeing.

This is some of what you can expect to be doing:

  • Model and monitor new active city networks
  • Identify and augment the existing network as required
  • Deliver short, medium, and long-term forecasts for all network components
  • Incrementally improve network capacity monitoring and operational excellence using automation and AI
  • Work with vendors to secure a repeatable supply chain

What you’ll bring to the role

You’ll have strong written and verbal communication skills, excellent analytics and mathematical skills, and well-developed troubleshooting methodologies. You’ll also have:

  • Experience with network troubleshooting and telemetry tools
  • Familiarity with virtualisation platforms, particularly QEMU (Quick Emulator) / KVM (Kernel-based Virtual Machine)
  • Programming skills in Perl, Rest, Shell, or Python
  • Good understanding of layer 2 & 3 technologies with an emphasis on Ethernet
  • Excellent understanding of platform monitoring and analytics tools

Diversity, Inclusion & Belonging

We’re a Times Top 50 Employer for Gender Equality. We’re endorsed by WORK180 and we’re a partner of Diversifying. We have pledged our commitment to the Armed Forces Covenant and we’re a Disability Confident Employer. Working together with our Employee Networks, we’re wholly committed to ensuring that our people’s voices are heard, and that everyone feels a sense of belonging and pride to be a part of CityFibre.

What you can expect from us

We want to offer you all the support you need to thrive inside and outside of work. This means giving you the tools to grow your career with us, as well as a comprehensive benefits package that you can adapt to your lifestyle. This includes 25 days annual leave, a day off on your birthday, a day off to support a charity or organisation of choice, a range of wellbeing and savings initiatives including private medical insurance, and supportive family friendly and menopause policies.
