Senior Network Engineer

As a Senior Network & Telephony Engineer, you’ll play a key role in delivering, supporting and evolving the core connectivity and communications platforms that Delt provides to its customers.

Working in a complex, multi-tenant enterprise environment, you’ll take ownership of a defined set of systems, ensuring they remain secure, available, resilient and efficient. You’ll lead on operational improvements, project delivery, incident resolution and system optimisation - while also providing technical guidance and direction to more junior engineers.

This is a hands-on senior engineering role with genuine influence. You’ll act as a subject matter expert, shaping standards, feeding into architecture decisions, and ensuring services are fit for both today and what’s coming next.

• Taking senior technical responsibility for one or more of the following system domains:
• Estate-wide boundary and filtering technologies (e.g. firewalls, proxies, SD-WAN, BGP)
• Distribution and access layer technologies across varied campus environments (switching, VLANs, Wi-Fi)
• Enterprise telephony solutions, including call routing and automated call distribution
• Leading the implementation of projects, enhancements and system improvements within your owned platforms
• Ensuring risks and issues are clearly documented, managed and mitigated in collaboration with the Service Owner
• Providing technical input into solution design, onboarding of new customers, and integration of new technologies, working closely with Technical Architects
• Producing and maintaining high-quality technical documentation, including designs, runbooks, asset records and configuration management data
• Owning change activity within live environments, including implementation, back-out and test planning, risk assessment and governance
• Monitoring system capacity, availability, security and performance, taking remedial action and escalating where appropriate
• Leading recovery processes for your systems and ensuring robust, tested recovery approaches are in place
• Identifying and assessing emerging technologies and trends relevant to your platforms
• Supporting the development of technical capability across the infrastructure team through documentation, knowledge-sharing and hands-on guidance
• Demonstrating a strong commitment to continuous professional and technical development
