As a Senior Network Engineer (Incident Response), you will play a critical role in incident investigations and infrastructure recovery, focusing on network isolation, restoration and hardening. You’ll be part of a high-performing CIRT Team responsible for supporting clients during and after cyber incidents, ensuring secure and resilient network operations.

Incident Response is a demanding and time-intensive role, often likened to emergency services in its urgency and unpredictability. When a cyber crisis occurs, Incident Responders are the first line of Defense, mobilized immediately to contain, investigate, and remediate the issue. These moments require extended hours, rapid decision-making, and a high degree of flexibility, often working through nights, weekends and holidays to restore normal operations.

The intensity of the role peaks during active incidents, where the workload can be relentless and the stakes high. However, this is balanced by periods of recovery and downtime once the immediate threat has been resolved. During these quieter phases, Incident Responders are afforded well‑earned time off to recharge, recognising the toll that crisis response can take.

To lead network efforts during cyber incidents, including isolating, rebuilding and securing network infrastructure, restoring connectivity, and implementing preventative controls. You will also support the Infrastructure & Investigation teams with escalations. Pre & post‑crisis you will contribute to the improvement of our service through better tooling, processes, documentation and knowledge sharing including performing some pro‑active functions to enable customers to improve their ability to respond.

This role is well‑suited to individuals who can rapidly develop a comprehensive understanding of a customer's environment—often in the absence of detailed documentation—and are capable of identifying and implementing architectural changes in real time in line with our methodologies.
