Yes, I basically enjoy my job :-)
As far as I can tell, designers and DV engineers are about equally content.
From what I've seen SW engineers are an even more content bunch.
I'm not well exposed to that branch -- what I've seen in job postings is "software QA".
From what I've seen, anything in the States that's labeled "QA" is starting in an underdog position.
The interesting thing here is that you write as if you basically enjoy your job. Not many people in software 'design verification' seem to enjoy their job, (a) if there is such a job role in software, and (b) if they ever wrote about it - I haven't seen much of that.
Maybe hardware has more interesting problems?
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
