From experience, there's no single place that will just work. Have to keep trying through multiple channels all the time.
Here are some ways that we try.
- LinkedIn Jobs, indeed etc like job boards
- HN (whoishiring), angel.co
- technology specific job boards (welovegolang, pycoders weekly etc)
- references through current employees, their past colleagues etc
- cold pings on Linkedin, Twitter, github
- Some slack/discord channels for specific technologies
In personal experience, quality of the crowd depends on the channel too, however, wouldn't call this a confirmed observation.
