dont know if you are interested but bex.io is hiring for security engineers/auditors, and most of their employees are remote. Since these guys puport to be a cookie-cutter template for running your own bitcoin exchange I'm sure they will need you. https://angel.co/jobs?slug=bex-io
I always thought you would get a lot of work via HN people. It surprises me but I don't find it hard to believe. Why it doesn't surprise me is because security and pen testing work is as much about sales, marketing and presentation - perhaps more than skill.
Some of the best security guys I know find it hard to pitch their services, so they end up working low-end generic programming or sysadmin jobs. I've tried to get more and more of them involved in my work (I do contract pen testing while also doing my own sec startup at the moment) by including them in proposals I write up, works out well. I messaged you on twitter.
