Ask HN: How can engineers profit from tech recruitment

How can an engineer capture some of the value from the tech recruitment market? It seems to me engineers are used as goods that are traded between people who don’t understand tech or the market. It's exploitative and opportunistic — how can a random person just show up in LinkedIn and start trading engineers and extract value from their major life choices?

Engineers understand the technology and market and would have a huge information advantage compared to someone with no experience in the field. Even just consulting on some domain/tech knowledge for recruiters would benefit the recruiters.

How can I, as an engineer, get some of that pie?
