My advice here is not going to be about listing a ton of places to widely post your job ad - while we do that, I really think it only accounts for maybe ~10% of our hiring success. I think ~90% of our strongest applicants come from either the 80K jobs board or from us deliberately reaching out to people and inviting them to apply.

Since you can't really do anything about the 80K jobs board (they don't accept solicitations), the single best thing IMO that you can do is proactively identify high-potential candidates and invite them to apply. Also, reach out to a group of diverse other people you respect and whom you think are good judges of talent and ask them who they think are the high-potential candidates and then invite those candidates to apply.

Another important factor: Hiring remotely gives us (Rethink Priorities) access to a much bigger talent pool than organizations that don't, but of course there's trade-offs there. That might explain another large portion of how we can get so many applicants.

Lastly, I think it's also worth investing a lot of time in creating a genuinely good workplace and then telling people about it so they know you have one. You can advertise all you want but people still have to choose to apply and they'll only apply to good places.

These three things matter much more than just posting everywhere.

Consider where EAs are and post in those places. Whether on twitter, the EA jobseekers slack, newsletters, etc etc.
