digital communications - Quality of experience engineer

I have noticed certain overlap between digital signal processing and quality assurance for jobs that require expertise in evaluating the quality of the transmitted signals on telecommunication systems like VoIP or IPTV. I have two examples:

For me, however, electronics engineer or quality assurance engineer are not terms that describe enough someone who is able to understand ITU-T standards (MOS, PSQM, PEVG, PESQ, POLQA, MUSHRA), quality of experience (QoE), network terminology (packet loss, bit rate, throughput, transmission delay, availability, jitter), DSP techniques (frequency analysis, FIR/IIR, sampling and quantization), and software programming.

Is there another name for this position? Is there a career path defined for someone who aims to work in this industry? Is this job profile something required nowadays by other companies?

PS: I wonder also if an expert like this can also participate in the creation of new algorithms and the evaluation of the quality of the architecture of DSP systems, as described here: https://www.eetimes.com/document.asp?doc_id=1275520

Answer

By all comments, and personal investigation, my understanding is that there is no such thing as a QoE engineer. From one side we have a quality assurance engineer role with technical expertise in real-time audio/video evaluation and computer networking (black box knowledge); and on the other side, we have the R&D and design engineers, with knowledge in the mentioned topics, and also signal processing, algorithm design, and human auditory-visual perception (including HCC).

If you belong to the second role then you either work for the academy, a standardization group (e.g. ITU-T), the government or an industry leader in multimedia equipment (e.g. Dolby). If you work in the first role then you come from a company that provides custom development services in projects that require a minimum level of certification.

There are some exceptions to the rule, like researchers leaving the academy to become entrepreneurs: https://www.ssimwave.com.
