Description
Wanstor is an award-winning Managed IT Services provider helping ambitious organisations use technology to achieve better business outcomes — securely, efficiently, and at scale. Established in 2002, we deliver end-to-end technology services spanning managed IT support, cloud, infrastructure, networking, security, communications, and AI adoption services.
This is a brilliant opportunity for a Senior Network Engineer who wants more than a traditional MSP engineering role.
You’ll join Wanstor as part of a small, dedicated IT team supporting one of our key customers , spending three days a week on-site at their offices in The Shard . It’s an impressive environment to work in, but more importantly, the role gives you the chance to get genuinely close to the customer, understand their technology estate and have real ownership over how their network evolves.
Rather than moving between customers or simply picking up tickets, you’ll become a trusted technical presence within the customer , taking ownership of complex networking issues, improvements and projects. You’ll work across BAU and project activity, helping to design, implement and improve their network environment while spotting opportunities to make things more resilient, secure and effective.
You’ll still have the backing, expertise and wider technical community of Wanstor behind you, but with the autonomy and ownership that comes from being embedded with a customer .
It’s a great fit for someone who enjoys being hands-on technically but also wants visibility, responsibility and influence — someone comfortable speaking directly with stakeholders, taking a problem away and owning it through to resolution, and playing a leading role in network projects rather than simply being handed individual tasks.
What You’ll Do
- Own, support and continually improve a Fortinet-led network environment
- Take the technical lead on network projects, from initial requirements and design through to implementation and handover
- Configure, manage and troubleshoot FortiGate firewalls, including policies, VPNs, routing, security profiles and connectivity
- Work across LAN, WAN, Wi-Fi, SD-WAN, switching, routing and firewalling
- Lead complex troubleshooting and resolve network issues that require deeper technical investigation
- Identify weaknesses, risks and opportunities for improvement across the network estate
- Work directly with customer stakeholders, translating technical issues and recommendations into clear, practical advice
- Own technical changes and ensure they're properly planned, tested, documented and communicated
- Produce and maintain network documentation, diagrams, configurations and technical standards
- Support network upgrades, migrations, refreshes and wider infrastructure projects
- Work alongside Wanstor's wider technical teams and third parties where projects cross networking, cloud, security or infrastructure
What You’ll Need
- Strong hands-on experience with Fortinet technologies, particularly FortiGate firewalls
- Good knowledge of Fortinet security, VPN and SD-WAN capabilities
- Strong understanding of core networking including TCP/IP, DNS, DHCP, VLANs, VPNs, NAT and network security
- Strong routing and switching knowledge
- Experience supporting and troubleshooting LAN, WAN and wireless networks
- Confidence diagnosing complex network and connectivity issues from end to end
- Experience delivering network changes, upgrades, migrations or implementation projects
- Comfortable working directly with customers and senior stakeholders
- Able to take a requirement or problem, work out the best approach and own it through to completion
- Strong documentation skills and an organised approach to change
- Experience within an MSP or customer-facing IT environment would be highly beneficial
What You’ll Love
- Generous Time Off: Enjoy 24 days of annual leave, increasing by 1 day each year up to 28 days, plus Bank Holidays.
- Continuous Learning: Participate in regular lunch and learn sessions with both internal and external speakers.
- Personal Development: Take advantage of 5 paid days annually to pursue new skills or knowledge.
- Volunteer Opportunities: Contribute to your community with 2 paid volunteer days each year.
- Team Spirit: Join a friendly team and engage in various social events organised throughout the year.
