Is circuits, amplifier, BJT applicable in current market?

It's true that much of the "heavy" systems work has migrated towards software techniques. That trend was beginning when I graduated in Electronics in 1968! In the end, though, it's an analogue world (until you get down to the quantum level, where it's merely uncertain). I've seen some horrendous hardware interfaces, fairly recently, which no amount of software tinkering can ever fix. If you've been taught worst-case design, consider yourself one of a rare and important breed. Don't abandon your electronics; keep up with it!

Having said that, you will need to gather some software skills to enhance your career opportunities and to understand software issues, which will come up all the time. Important keywords for you, I suspect, are "embedded" (as you know) and "DSP". Software is much easier to learn than Electronics, as I know, having done both. That's not to say it's trivial!

Congratulations on entering your career from the right end (in my opinion).

I think having knowledge of circuits is very helpful in the embedded world. I'm a software guy and I wish I had that knowledge. I'm working on it. As it is, I must work with good enginers/technicians to solve problems.

Applications notes and datasheets have been know to be very wrong or incomplete. Likewise, technical support is not always all that helpful. The more you know, the better.

analog design enginneer and the most valuable of these is the rf design engineer.

This is a bit like saying that learning the alphabet is not useful or important for learning philosophy :)

Electronics knowledge is *invaluable* for an embedded developer. You have the easy path ahead of you; I started in software and learned hardware later; starting with digital hardware. I am still learning about analog issues; I wish I had learned things the "right way up" because it would have been much easier.

You could contact companies doing

- analog integrated circuit design

- high power audio/switching mode power supply design

- designing products for high frequencies (f > 1 GHz)

All the digital/software stuff you mentioned is huge and (long-term) a growth market, but 'general hardware knowledge' including analog is still important. Just page through the book "High-Speed Digital Design" and you'll see a lot of the basic analog stuff (pulses through RC and RLC circuits) stuff is used. Post this on sci.electronics.design and see what response you get.
