Careers pages are a bit broken, for instance, "Software Engineer, Runtime Team" role says "Experience developing production software in Go or Ruby" (https://www.heroku.com/careers/software-engineer-runtime-tea...).

When you click on the "Apply for..." button, another page appears saying it's for "Distributed Systems Software Engineer - Public Cloud (Senior/Lead/Principal)" role and mentions "Deep knowledge of programming in Java, Golang, or Python". So not only the title of the role changed, but all the requirements as well.

Is this remote worldwide or in the US only? The job ad says "employees on several continents and more than a dozen countries" which implies it's world-wide, but when I apply it says "I understand that upon employment, proof of legal right to work in the US and completion of an I-9 form will be required".

We are flexible on location, I'll bring this to the attention of the recruiting team.
