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:
Ask HN: Who is hiring?
“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.
Ask HN: Who wants to be hired?
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.
Ask HN: Freelancer? Seeking freelancer?
This monthly thread is dedicated for freelancers only. Here is the google link for past threads.
Bonus tip: follow “Show HN”
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.
