We have used Cloudflare products ourselves, including Turnstile to protect apps from bots, so we know first-hand how solid their tech is, and that matters when you are thinking about where to work. With over $2.1 billion in annual revenue, 34% growth in Q4 2025, and $4 billion+ in cash reserves, Cloudflare is financially rock-solid and still growing fast. They operate one of the largest networks in the world, sit in front of roughly one in five websites, and are pushing hard into AI infrastructure and the agentic web. The scale of what they do is genuinely impressive; so many of the apps and services you use every day depend on Cloudflare without you even knowing it. Across Glassdoor, employees consistently highlight the great products, friendly and smart colleagues, positive working environment, and genuine flexible hybrid and work-from-home arrangements. They also offer unlimited paid time off and have a real focus on diversity and inclusion. We should be upfront, though: the Glassdoor rating sits at 3.4, and reviews are mixed. While the culture and people are widely praised, compensation competitiveness and slow promotion processes are recurring pain points. However, if you want to solve hard, Internet-scale problems at a company whose products you probably already rely on, Cloudflare is a brilliant place to do that.
