Hacker News can be a great source of finding engineering talent for your company. Here are few ways I have found on HN to source great talent for my own startup:
“Who is hiring” is a monthly thread where companies can post technical job openings free of cost. A new thread is featured on HN homepage on first weekday of every month. For example, this is the “Who is hiring” thread for July 2016.
You should also check out a this cool interface for Who is hiring threads byMicah Wylde.
Unlike “Who is hiring”, where companies post job opening, “Who wants to be hired” is a monthly thread where active job seekers post about themselves. Majority of job seekers are remote workers but you can also find candidates who are willing to relocate.
Here is the google link to find past threads for “Who wants to be hired?”
This monthly thread is dedicated for freelancers only. Here is the google link for past threads.
Show HN is a place where hackers post their interesting projects and showcase their skills. Check that space regularly to connect with smart people who are working on technologies relevant to your company.
