Thanks; I googled it and the press was heaviest in April 2017 for a new London office, so this is a helpful correction for me. Though deeper inspection found 2013 (https://www.facebook.com/Cloudflare/posts/10151742549255432), so I probably should've just googled harder.

It also changes the equation substantially since the rest of my assumptions were based on 2017, though I wonder how much the environment also changed between 2011 and 2021, brexit aside?

Cloudflare's London office remains large and important. We've built up Lisbon as an alternative location in part to give folks a choice between London and a continental European city and in part because we are hiring so fast it's good to hire in multiple places.

Why not just open to remote hiring across Europe then, rather than be location-dependent?

Just opening for “work from anywhere” has right to work, legal and tax implications for the employee and company. So we’ve taken an approach where people can work where we have a legal entity.

We also do believe that time in the office is valuable and prefer employees be “near” the office so they can work together with other in the office as needed.

But this isn’t set in stone. Maybe totally remote would be great for us, we’ll experiment and see.

They're doing that as well https://www.cloudflare.com/careers/jobs/
