As a Cloud VOIP Engineer you will be responsible for a variety of activities relating to our platform, vendor interop and customer support.

    • Ability to troubleshoot advanced SIP interoperability issues between VOIP services.

    • Good listening and rapport building skills.

    • Ability to deal with a variety of different situations, some of which may be challenging in terms of timescales, or which will seem high pressure.  


Qualities and behaviours we’re looking for:

  • A strong desire to make our customer’s happy.  To genuinely listen to their needs, to delve into their requirements and the quirks of their configs, and the tenacity and problem-solving abilities to come up with and explain solutions.

  • Striking the perfect balance between going the extra mile, but not overdelivering to the extent that clients ask us to so stuff their teams are better placed to do.

  • Preference for working in a fast-moving, constantly changing environment.

  • Love for, and curiosity about, new technologies and methodologies and how they shape the world.

  • Experience of working in a startup or scale-up with an understanding that everyone needs to roll their sleeves up and get involved.
