Our Technology and Design team plays a vital role in keeping OS at the cutting edge of geospatial capability. We work across the business to deliver customer-centric technology services that make a real difference. Join us and you’ll have the opportunity to make an impact, supporting technology that underpins critical services and helping shape the future of networking at Ordnance Survey.
We’re looking for an experienced and influential Lead Network Engineer to provide technical leadership and strategic direction for OS’s enterprise network infrastructure. You’ll lead the architecture, design and delivery of complex network solutions across our data centres, cloud environments and remote sites. As the principal technical authority for networking, you’ll help ensure our network services remain secure, resilient, scalable and fit for the future.
These responsibilities reflect the current Lead Network Engineer role profile. This is more than a hands-on technical leadership role. You’ll lead and develop a team of network engineers and technicians, helping to build capability, share knowledge and create a collaborative and inclusive engineering culture. You’ll also work closely with teams across cybersecurity, infrastructure, development and applications while helping shape our network technology roadmap, investment priorities and future strategy. You’ll work across a varied networking estate. Key technologies within the team include Cisco switching and routing, Cisco ISE, Cisco Meraki, Check Point firewalls, F5 BIG-IP and Azure networking, so experience across several of these technologies would be particularly valuable.
What we’re looking for
- Extensive experience working with enterprise network infrastructure and leading complex or large-scale network initiatives.
- Expert knowledge of networking protocols and technologies including BGP, VLANs and VPNs.
- Strong hands-on expertise across routing, switching, wireless, firewalls and cloud networking.
- Strong understanding of modern network security principles including network segmentation and zero-trust approaches.
- Experience with network monitoring, automation and scripting.
- Strong troubleshooting and problem-solving skills for complex network and service issues.
- Excellent leadership, communication and stakeholder management skills.
- The ability to balance operational priorities with longer-term strategic objectives.
- Experience leading, coaching and developing engineers and supporting their professional development.
- Industry-recognised networking certification such as Cisco CCNP/CCIE or equivalent experience.
You’ll have the opportunity to:
- Lead the architecture, design and delivery of enterprise network solutions.
- Act as a technical authority for network engineering.
- Oversee network performance, capacity and operational health.
- Provide technical leadership during complex incidents and support root-cause analysis.
- Drive automation and continuous improvement to increase reliability and efficiency.
- Lead, coach and develop network engineers and technicians.
- Identify capability and skills gaps and support development and succession planning.
- Work closely with cybersecurity and other technology teams to deliver secure, integrated services.
- Develop standards, documentation and technical best practice.
- Evaluate emerging networking technologies and work with technology partners and vendors.
- Contribute to strategic planning, investment, budgeting and network risk management.
- Define and maintain the network technology roadmap.
The rewards
We want you to love what you do and feel supported to do your best work. Our benefits include:
- Competitive salary and pension (OS contribute up to 12.07%)
- Performance‑related bonus (where applicable)
- 28 days annual leave plus bank holidays (increasing with service)
- Enhanced family leave, including paid partner leave
- Hybrid and flexible working options
- Learning and development support, coaching and mentoring
- Free subscription to OS Maps and access to wellbeing support
- Volunteering leave and matched fundraising
Location & Working Pattern
The role is based from OSHQ in Southampton, with OS operating a hybrid working model. Regular office presence will be required because of the hands-on nature of supporting our enterprise network infrastructure.
Security & eligibility
Given the nature of this role, the successful candidate will be required to obtain and maintain the appropriate level of UK national Security Clearance. You must therefore be willing and able to undertake the necessary security vetting process.
Inclusion at OS
Research shows that people from underrepresented groups often hesitate to apply unless they meet every requirement. At Ordnance Survey, we’re committed to building a diverse, inclusive and welcoming workplace. If this role excites you but your experience doesn’t match every point, we encourage you to apply. You may be the right person for this role or another opportunity at OS.
