Software Developer - VoIP

Software Developer – VoIP – the opportunity

We are delighted to be working again with a regular client who are a pioneer of the VoIP industry, a well-established, award-winning business with lots of exciting things going on.

The particular role is focused on the development of the company's core Voice platform. You'll be working in a team of four, developing new features, updating existing systems and introducing new technologies into the platform. We're looking for someone eager to contribute new ideas and – as the role is fully remote – we need someone who is good at collaborating remotely and working autonomously.

The core language used will be Python. There is some legacy code in C/C++ so some exposure to that would be helpful. Telecoms experience is essential – SIP for instance – as is deep knowledge of Linux.

Given the remote nature of the role, we do have some flexibility to hire outside the UK, but strictly within EU/EEA and within 2 hours of GMT. We do need candidates to be fluent English speakers.
