Software Engineer, Privacy Team

Available Locations: London, Lisbon or Austin

About the department

Emerging Technologies & Incubation (ETI) is where new and bold products are built and released within Cloudflare. Rather than being constrained by the structures which make Cloudflare a massively successful business, we are able to leverage them to deliver entirely new tools and products to our customers. Cloudflare’s edge and network make it possible to solve problems at massive scale and efficiency which would be impossible for almost any other organization.

What you’ll do

Here at Cloudflare, privacy is core to what we do. This includes giving users more control over their data, working with browser and operating system vendors to reduce cross-site tracking, and/or building first-party, privacy-focused products for customers ourselves, we’re increasingly working to improve the default state of privacy and security on the web.

On the job, you will be part of the team building our globally deployed, production-grade privacy proxy platform – the technology that powers Private Relay and Microsoft Edge Secure Network. You will also have the opportunity to work on the cutting edge of privacy Internet standards. We’re looking for someone excited about building – and helping us brainstorm – the future of privacy infrastructure at Cloudflare.

Bonus Points:

• Experience contributing to major browsers, web frameworks, proxies, or distributed systems projects.

• Rust experience, inc async Rust, is a significant advantage, but we are open to those who want to learn it
• Contributions to open-source projects
• Demonstrated ability to improve products/services by debugging and resolving network-level and application-level performance bottlenecks.
