From my understanding, you want to be exposed to multiple technologies with minimal coding. I think you should look towards architecture, with a focus on very low-latency networking applications like high frequency trading. It is a very interesting field, where the design of the whole system matters (optimisations in each module as well). In systems like such, the design is way more important than writing code and you also get to go deep into the hardware side of things.
