CYFOR is a leading nationwide provider of Digital Forensics, eDiscovery and Cyber Security services to law firms, corporate organisations and law enforcement.

The Role

Due to the continued growth of our CYBER Division, we are looking for an experienced Network Infrastructure Engineer to work as an incident responder.

Where a client’s infrastructure has been severely disrupted by CYBER Events, your role will be to help clients get their networks back working as quickly as possible. With consummate client-facing skills, you’ll lead each project from the front with calmness, assuredness and professionalism. Key to being a success in the role is your ability to troubleshoot and think on your feet in a fluid environment. You’ll also be able to demonstrate flexibility, commitment and integrity along with confidence and a can-do attitude.

The ideal candidate will have at least 5 years of experience in network infrastructure design and implementation.

In return, you’ll receive a salary commensurate with experience, training, overtime and excellent career prospects. You’ll enjoy a varied and highly fulfilling role, working with great colleagues in a fantastic atmosphere. This is a unique opportunity to join a highly successful business that truly focuses on its main asset, the team.
