Founder here. Could you point us to an application where we didn't respond? You can DM me an email on x.com/justjake and I'm happy to check what happened
Ian is our recruiter, I checked AshBy, and basically everyone's getting at least a "Sorry you're not a fit" email (save for people spamming the inbox multiple times)
As for why we've posted the same job many times. We're an early stage infrastructure company, and it's surprisingly hard to find people who go really deep (Example: We've built our own orchestrator, so we're looking for people who would build kubernetes instead of use it)
In that case I'm assuming something went wrong when I sent the application as I never got anything back from you. I just sent it again so hopefully this time it'll be different :)
