Earlier quoted context omitted.

Remote (US-based or Canada-based only). Must be authorized to work in the US (no visa sponsorship available).

Updated to reflect our strong preference for US/CA. We have made exceptions in the past. Since there are comments about this above, I want to highlight that we've hired successfully on HN for several roles for our current small team. We hired 1 of 2 roles last month, and are still looking for a candidate for this role, which is why I'm posting here again.

Great to hear! p.s. I just copy-pasted to help, not to critique.

Hey Jared! I just applied to the special projects SWE position. My offer I had got rescinded so I would appreciate any help you could provide.

Thanks, we'll take a look and get back to you this week! Quick heads up: there's a project link in your resume that sends me to a page with the text "This service has been suspended by its owner."

Any idea if you guys will be hiring for technical roles in Canada any time soon? I'm a dual Canadian-Estonian citizen and I'm intending to move to Europe at some point in the next year or two but until then I'm based on Canada.

It would be super cool to start working for an Estonian company before I even move there.
