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
In my experience in the defense industry, the quality assurance engineers are mostly just “box checkers” that have limited understanding of how all of the individual facets of the algorithms and systems work. We have design engineers, integration engineers, and then the QA engineers. I have never seen an integration engineer or QA engineer get involved in any sort of design; the skill sets for each position are very, very different. It’s one thing to know what something is, but it’s something else entirely to be able to use it in a creative way to solve a problem.

Again, this is just my experience in the defense industry within the US. Other countries and industries may be a bit different though!
