Job description

Senior Network Engineer at Wifinity - Remote UK — Wilmington

This role is described as remote-first, which is a meaningful signal for location-independent workers — however, there are important caveats that nomads must weigh carefully.

On-call obligations are a significant constraint: you're expected to join a rota covering one in four to six weekends, requiring you to be reachable and responsive outside normal hours. This means you need a reliable, fast internet connection at all times — not ideal if you're hopping between hostels or rural co-working spots.

Timezone alignment: While no explicit UK hours are mandated, the role involves attending customer meetings and collaborating with internal teams at Wifinity, a UK-based company. In practice, you'll need to be available during UK business hours (GMT/BST), making Central European and West African time zones the most compatible for a nomad lifestyle.

Visa considerations: Since this is a UK employer, you'll likely need the right to work in the UK, or at minimum a legal basis to be employed remotely. The UK does not currently offer a digital nomad visa, so EU/EEA nationals post-Brexit may face complications. If you're already UK-based, remote work from abroad short-term may be possible under tourist visas in countries like Portugal or Spain.

• Lisbon: Monthly costs ~€1,800–2,500 — a UK senior NOC salary would stretch comfortably here
• Bangkok: Monthly costs ~£900–1,400 — excellent value, but GMT+7 makes on-call coverage very challenging

No explicit travel perks (coworking allowance, equipment stipend) are mentioned. This role suits someone UK-resident who wants remote flexibility, not full location independence.

About Us
We're a UK-based managed internet provider delivering B2C & B2B connectivity solutions for organisations and their customers.

At Wifinity, we're passionate about providing the most reliable, high-speed broadband and site-wide WiFi networks for modern living. We focus on delivering secure, ultra-fast connectivity that meets the demands of today's digital lifestyles — whether in military accommodation, student housing, holiday parks, multi-tenant properties, or retirement communities.

We believe in delivering that experience sustainably. As a responsible broadband provider, we're committed to reducing our environmental footprint through energy-efficient infrastructure, smart power management, and ongoing improvements.

The Opportunity
Reporting to the Core & Platform Manager, this role combines deep technical expertise with engagement in pre-sales and solutions. You will be personally involved in the implementation of solutions for new Wifinity clients, as well as supporting complex incident and issue resolution on our existing network .

Key Areas of Focus
Your day-to-day responsibilities will include:

• Own and resolve high-impact incidents escalated from L1/L2 teams, including root cause analysis and post-incident reviews.
• Lead configuration, monitoring, and maintenance of network systems including firewalls, SD-WAN, GPON, routing, and WiFi platforms.
• Review and implement complex RFCs, ensuring minimal disruption and alignment with CAB processes.
• Maintain detailed records of incidents, resolutions, and network changes.
• Contribute to internal knowledge bases and mentor junior staff.
• Identify systemic issues and propose enhancements to tooling, workflows, and monitoring thresholds.
• Key contributor and workstream owner of Product Operations and Platform standards.
• Provide strong representation within Network Operations' Architecture Board.
• Join the on-call rota (one in four to six weekends) in the event that technical escalation beyond L2 capability is required outside of normal working hours.
• Collaborate with sales and solution architects to scope and design network solutions for new opportunities.
• Provide technical input into customer proposals, including BOMs, SLAs, and service design documentation.
• Provide technical input on both internal and external high- and low-level design documentation.
• Attend customer meetings to support technical discovery and solution alignment.
• Work alongside the physical delivery team to implement complex customer-specific configurations.
• Build trust with customers and internal teams through expert handling of complex queries, problems, and incidents.
• Mentor junior engineers and contribute to team development and knowledge sharing.
• Deliver all set targets to contribute to a successful business function in line with strategic objectives.
• Undertake any other duties aligned to the scope and level of the role.

About You
You are a self-motivated problem solver with a passion for network operations and service excellence. Comfortable working independently and collaboratively, including occasional out-of-hours support. You are committed to mentoring and knowledge sharing across the NOC team.

Experience Required:

• Minimum 5 years in a NOC or ISP/Telecoms environment, with proven success in incident resolution and escalation handling.
• Experience supporting pre-sales engagements and contributing to solution design.
• Deep understanding of LAN/WAN/WiFi, routing protocols (BGP, OSPF), and security platforms (e.g., Fortigate, RADIUS).
• Familiarity with monitoring platforms, ticketing systems, and diagnostic tools (e.g., Wireshark, SNMP, syslog).
• Exposure to cloud networking (AWS, Azure) and automation/scripting (Python, Bash) is a plus.

Desirable Certifications:

• CCNP, CWNA, ITIL Foundation, or vendor-specific certifications. (Wifinity deploys equipment from Ruckus, TP-Link, Adtran, Mikrotik, and others.)

We Offer a competitive salary and benefits package, including an enhanced annual leave scheme starting at 25 days, with additional holiday entitlement awarded through length of service, alongside a remote-first working environment that gives our employees greater flexibility and supports a healthy work-life balance.

Is this role fully remote or is there an office requirement? Wifinity describes this as a remote-first working environment, giving employees greater flexibility.

What certifications are preferred for this role? Desirable certifications include CCNP, CWNA, ITIL Foundation, or vendor-specific certifications relevant to Ruckus, TP-Link, Adtran, or Mikrotik equipment. Is a background check required? Yes, the successful applicant will receive an offer subject to satisfactory completion of a basic DBS (Disclosure and Barring Service) check. What is the annual leave entitlement for this role? The role offers an enhanced annual leave scheme starting at 25 days, with additional holiday entitlement awarded based on length of service.
