Networks & Security Pre-Sales Consultant

This is a strong opportunity for a technical pre-sales consultant or systems engineer to join an engineering-led organisation, where solutions are built properly, not just sold.

The role is ideal for someone who enjoys being both customer-facing and technically credible, with the ability to translate business requirements into real-world, deployable solutions.
