Help with deciding NOC code

[aman.alam]

Hi Folks,

I had been a Software Engineer till late 2015 and then I switched to a job role where I am primarily evangelizing the software tools of my employer, and at the same time I am making software to help the other software engineers using my company's tools.

I can't ascertain if this role comes under Software Engineering (2173), or something else?

What I tried so far:

• I tried searching for "Developer Advocate" which gives me NOC codes related to legal professions.
• And when I tried searching for "Developer Evangelist", I get NOC codes related to religious services.
• And whatever codes and titles I am getting in areas of marketing, don't match this job

I am pasting here the R&R of this job, can anyone please help me with what NOC codes would match the best?

Thanks in advance!
