Job description
Central London, with travel to other UK locations expected on a weekly basis.
This role qualifies for a specialist capability‑based pay approach, which recognises and rewards cyber technical expertise. Based on an assessment of skills and experience at interview, candidates may be eligible for an additional skills payment, potentially increasing the salary to £52,972.
To retain the higher salary, individuals will need to demonstrate and accredit their skills against our Cyber Technical Framework within the first years of employment. If the required skills cannot be evidenced initially, support and an opportunity to address any gaps will be provided. If this is not achieved by the end of the first year, it may result in a return to the lower end of the stated pay range.
As skills develop and are maintained, there will be opportunities to progress further within the pay range at this grade. Employees can apply for recognition of increased skills levels at regular intervals, in agreement with their line manager.
Flexible working
This role is primarily office‑based due to the nature of the work. However, flexible working arrangements are supported, including flexitime with flexible start and finish times, as well as the option to work compressed hours.
The role
Your responsibilities will include:
- Install, configure, and manage remote infrastructure such as firewalls, routers, switches and servers.
- Investigate technical issues and support the administration of a multi‑vendor environment.
- Contribute to the development and implementation of automation systems.
- Collaborate closely with internal stakeholders to understand and meet their unique requirements.
- Plan and undertake individual project work in relevant technical areas, aligned with the team’s priorities.
- Participate in an optional on‑call rota and cover shifts when required.
- Work with industry partners at the cutting edge of networking technologies and attend international events as appropriate.
About you
We are looking for candidates with a sound foundation in network engineering and previous experience in a technical industry role.
Key technical skills:
- Proficiency in Layer 2 and Layer 3 technologies.
- Experience applying network configurations on GNU/Linux‑based systems.
- Interest in cyber and global datacentre interconnection.
We would also welcome industry accreditations such as Red Hat, Arista, Juniper or Cisco – if you do not currently hold them, we will support you in gaining them once in the role.
A commitment to ongoing learning and professional development is essential.
As someone comfortable working on projects within cross‑functional teams, you will demonstrate proven problem‑solving skills and the ability to clearly communicate internet infrastructure concepts to both technical and non‑technical audiences.
Physical requirements may include lifting, carrying, and moving equipment. A fitness assessment will be conducted during the application process.
Training and development
On joining the team, you’ll participate in an induction, shadow experienced team members, and receive a buddy to support your settling‑in process. You will be introduced to key partners, customers and stakeholders.
You will be encouraged to join the Cyber Technical Framework (CTF), which helps assess your knowledge, skills and attributes as a cyber technical specialist. Membership is available through an application process and skills‑based assessments.
Additional training opportunities include courses in management, leadership, equality, diversity and inclusion, and specialised technical projects. We support you in achieving relevant professional qualifications.
Rewards and benefits
You’ll receive a starting salary of £44,190 plus the following benefits:
- 25 days annual leave (increasing to 30 days after 5 years’ service) and 10.5 days of public and privilege holidays
- Opportunities for recognition through our employee performance scheme
- Dedicated development budget
- Interest‑free season ticket loan
- Excellent pension scheme
- Cycling-to‑work scheme
- Facilities such as a gym, restaurant and on‑site coffee bars (at some locations)
- Paid parental and adoption leave
