Third Line Support Engineer

Woodford Green & South East

This is an exciting opportunity to join a well-established, progressive and forward-looking Managed Service Provider and IT Consultancy.

We are looking for a talented, proactive and analytical 3rd Line Engineer to join our busy and dynamic Managed Services support team supporting a diverse range of cloud and server-based infrastructures for small to medium-sized organisations.

You must have a professional, flexible and personable approach to client relations and should demonstrate initiative and possess the ability to prioritise tasks yourself.
