The Role In a Nutshell

Own the technical health of a live, business-critical managed service end to end, 24x7x365, for one of the UK's most demanding enterprise customers. This is the role for a hands-on Cisco network engineer who wants to be the definitive technical authority on a service: the person who leads the room during major incidents, troubleshoots the toughest problems on complex data networks, and turns demanding networking estates into stable, resilient, improving platforms. This is deep network engineering, not an infrastructure or cloud IT role.

The Business

One of the UK's most established communications and technology businesses, serving large enterprise and public-sector customers with mission-critical networks, voice and managed services. With significant annual investment in research and development and a substantial UK engineering workforce, this business has the scale, the technology and the customer base to take on the country's most complex programmes. The business invests genuinely in career development, world-class training, and the kind of work that accelerates a technical career.

The Role

As the technical authority on this service, you'll provide deep technical support and end-to-end ownership for maintaining the service. You won't be buried in a ticket queue; you'll be the main technical point of contact during live service, linking customers, internal resolver teams, suppliers and third parties for the complex decisions that keep services stable and secure.

At its core this is a deep network engineering role. You'll be hands-on across complex data networks, routing and switching, leading the technical troubleshooting on the hardest incidents. Cisco is the baseline we're looking for; experience with Aruba is a real plus, and as this is a growing area of the estate, training will be provided to bring your Aruba skills up to speed.

You'll assess complex in-life changes and clearly explain impact, risk and options to customers, account teams and delivery partners. When major incidents hit, you'll lead them to resolution, coordinating multiple teams, challenging delays and cutting through unclear ownership to protect customer outcomes.

Beyond the day-to-day, you'll actively manage the technical estate, spotting capacity limits, end-of-life risks and vulnerabilities before they bite. You'll challenge current designs, propose improvements that increase performance and resilience, and keep documentation sharp. This is a role built on authority, influence and genuine technical credibility across networking technology.

Skills & Experience

• Strong, hands-on Cisco network engineering as the core requirement: CCNP level routing and switching (or demonstrable equivalent depth), with proven troubleshooting of complex incidents on live data networks
• Aruba experience is an advantage rather than essential; as this is a growing part of the estate, training will be provided to bring the right Cisco engineer up to speed
• Proven experience technically supporting a 24/7 live managed customer solution across networking technology, working with a host of third parties and suppliers
• Strong working knowledge of ITIL practices
• Strong technical governance and risk-based decision making, with the ability to set and interpret technical standards and make defensible decisions
• Demonstrable incident leadership and operational control, coordinating stakeholders and driving timely restoration under pressure
• Deep end-to-end service understanding, including how upstream and downstream dependencies affect outcomes in production
• Strong stakeholder management and the ability to communicate complex technical issues clearly
• Ability to obtain and hold all required clearances (SC, NPPV, etc.)

The following would be an advantage:

• Exposure to complementary networking technologies (Aruba, Juniper, Fortinet, SD-WAN)
• Automation and observability experience: tooling, dashboards, alert tuning and runbooks
• Commercial awareness of SLAs, OLAs, penalties and regulatory expectations

Your Responsibilities

• Own the technical health of the live service end to end, ensuring changes, incidents and improvements protect customer outcomes
• Assess complex in-life changes and clearly explain impact, risk and options to customers, account teams and delivery partners
• Act as the main technical point of contact during live service, linking customers, internal teams and partners for complex decisions
• Lead complex incidents to resolution, coordinating multiple teams and challenging delays or unclear ownership
• Work with internal resolver teams, suppliers and third parties to operate stable services and resolve issues quickly
• Challenge current designs and propose improvements that increase performance, resilience and value
• Actively manage the technical estate, identifying capacity limits, end-of-life risks, vulnerabilities and required actions
• Build trusted relationships with customers, suppliers and internal teams, influencing through expertise and authority
• Keep all technical documentation accurate and up to date

Other skills required:

• ** Technical Authority ** - Credibility to set technical direction, interpret standards and make defensible, risk-based decisions others trust
• ** Incident Leadership ** - Ability to take control during major incidents, maintain situational awareness and drive clear comms to timely restoration
• ** Stakeholder Influence ** - Exceptional communication skills, building rapport with customers and suppliers and influencing through expertise rather than authority alone
• ** Improvement Mindset ** - A proactive instinct for spotting risk and inefficiency early and driving meaningful service improvement
• ** Coaching & Knowledge Transfer ** - Ability to upskill operational teams, transferring customer-specific knowledge and technical insight

Benefits

• 10% on-target annual bonus
• 10% company pension scheme
• Company share saving schemes
• 25 days annual leave plus bank holidays, increasing with service
• World-class training and development opportunities
• Wide range of flexible benefits
• Hybrid working: 3 days on site, 2 days remote
