Transferable skills from hedge fund?

I have been working for a while in a big platform-ish hedge fund under a PM as a junior systematic quant. I do data ETL, signal research, risk analysis and software development everyday (we are a small team so you have to touch all front lines).

I am considering a few years down the line, and it looks like a lot of the prop shops in Chicago are very laid back - much better than the atmosphere here in an HF (also NYC is really expensive).

What I am curious about is - how much skills are transferable between a systematic HF and a market making firm? It looks like prop shops have much higher technical edge and the core business is quite different (for example I heard most prop shops avoid overnight positions which is very rare for HFs).

I would appreciate all inputs.
