I'd like to put in a word for the Career Agency team at http://OfferLetter.io - we are building the first true talent agency for tech. We align incentives with individual engineers (and do not take money from companies), help them improve their messaging and polish, intro them directly to CTOs and VPs to help cut past recruiting bullshit, and provide negotiation advice.
We want everyone to find "the team", not "a team".
I'm an ex-Twitter (Growth) / ex-Amazon (Identity) engineer, and am building what I would have wanted at every step of my career.
One of our client profiles [#35 employee at Twitter] is up here, for the curious:
 See http://OfferLetter.io for more information
 We are neither recruiting agency (since we do not take money from companies) nor job board, and as such are compliant with the terms of the post
 We are located in San Francisco, but have worked with people in Seattle, New York, and Austria, and regularly help folks on visas.
Seriously cool idea. Keep it up!
