Senior Software Engineer - Client Mobile and Desktop Apps

At Cloudflare, we're not looking for people who wait for a polished roadmap; we're looking for the builders who see the cracks in the Internet that everyone else has simply learned to live with. We value candidates who have the instinct to spot a "normalized" problem and the AI-native curiosity to create a solution using the latest tools. Our culture is built on iteration, leveraging AI to ship faster today to make it better tomorrow, while ensuring that every improvement, no matter how small, is shared across the team to lift everyone up. If you're the type of person who values curiosity over bureaucracy, and that AI is a partner in solving tough problems to keep the Internet moving forward, you'll fit right in., We're looking for a Senior Software Engineer to join our Cloudflare One Client team.

You will also have to interact with other languages, such as Flutter, Swift, Java, Kotlin, C#, Rust, C++, and C. You'll be expected to improve the code quality and to build solid, testable, and well-documented foundations., * Great experience successfully using different typed programming languages, such as Swift, Kotlin, Java, C#, as well as lower-level languages, such as Rust, C, C++.
