Ask HN: How to make inroads into quantitative finance as an engineering PhD?

I've read articles[1] going over the checklist of skills needed for a quant finance career (optimization theory, low-level/real-time computing etc.). This is in my wheelhouse.

However, networking-wise, how does one make inroads into the finance career? (1) Are there ways a quant CV is different from a software engineer/researcher CV? (2) Are there places more popular for quant job postings? (3) What does a quant recruiter look for when evaluating candidates (published papers, open source stuff etc.)?
