## Description

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.

What you'll do

 * Acting as a Senior Infrastructure Engineer within Delt's Connectivity & Communication platforms, operating as a subject matter expert in your specialist area
 * 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
