About the role
About the team
The Network Platforms team contributes to Traffic Management functions at Cloudflare. One of the multiple teams responsible for the systems that optimize the flow of traffic into, through, and from Cloudflare's global network.
You would be working on the latest Linux network technologies and low level details of the network protocols. The code written would be running on thousands of servers and will be directly impacting each of the packets crossing the network infrastructure, that directly maps to numerous products and millions of customers. These systems are key to Cloudflare's mission to make the internet faster, safer, and more reliable.
Our team at Cloudflare operates under a "Run What You Build" model. This means we are responsible for the health of our systems and actively participate in our team's on-call rotation as part of our operational duties.
What you'll do
You will build and extend various systems that carry traffic end-to-end on the egress path of Cloudflare network. Starting at the host server linux kernel, with integration towards the network hardware dataplane until the physical Interconnect to an adjacent network. Millions of customers depend on these systems even if not directly visible to them. You'll be solving problems of massive scale and significance, and shaping the future of reliability and performance on the Internet. You will collaborate with engineers across the company, from operations teams to the teams building customer-facing products.
What we are looking for
We are looking for smart, innovative team players that have experience in covering Linux kernel network stack development (particularly with eBPF), complex distributed systems, and understanding of internet protocols and technologies. Particularly, growth-oriented individuals who enjoy being outside of their comfort zones, are comfortable in a fast-paced but sensible work environment and that value and lead with curiosity and empathy.
Role requirements
- Systems-level programming experience in Go, Python, Rust, C, or C++
- A solid grasp of BGP and internet routing.
- Relish opportunities to dive into new technologies, and a demonstrated ability to do so
- Experience in implementing, deploying, and debugging mission-critical distributed systems
- Strong collaboration and communication skills.
Skills the role requires, we are happy to help you learn on the job.
- Familiarity vendor switching SDKs
- Familiarity with SR-MPLS and sFlow, BGP-LS & PCE protocols
- Experience writing packet-processing software (eg, eBPF at TC or XDP, DPDK)
- Experience participating in an on-call rotation.
