Software Engineer, Network Security

About the team
Cloudflare is redefining the way networks are run at scale. Our Network Services product suite puts the connectivity, scale, and performance of Cloudflare's global network in front of customers' network infrastructure and private networks, providing a single pane of glass for network connectivity, visibility, and operating network functions like DoS mitigation, Next-Gen Firewall, IDS/IPS, WAN optimization, and more. We are a team of engineers and product managers who obsess over quickly building products that solve real customer problems using innovative technologies and techniques which leverage Cloudflare's unique architecture and global network footprint.
About the role
We are hiring engineers of all experience levels across many of our teams. Some of the things our teams work on include:

• A Linux kernel-based networking dataplane which ingests and forwards traffic from some of the largest networks in the world
• A userspace networking service which acts as a hub between our Network Services and Zero Trust systems, enabling every customer to access every product
• Network software running on a hardware appliance that provides zero touch connectivity to the Cloudflare network and SD-WAN functions
• Next-generation firewall functions implemented across Linux netfilter, eBPF, and userspace packet processing
• Flow and log collection, correlation, and analytics systems to provide customers with unparalleled visibility into their own networks
• Control plane systems which allow customers to simply express complex network configurations

As a Software Engineer on our team, you will work across a wide range of technologies and systems to deliver new features, improve performance, and increase the scalability of our Network Services products. You'll build, deploy, and operate your team's systems on top of one of the largest edge networks in the world. You'll partner with some of the best engineers and product managers to solve big problems that have a meaningful impact in the lives of our customers and users.
We're looking for curious, empathetic engineers who are excited to join us in changing the way networking is done!
