Senior Software Engineer - WARP Edge Service

Available Locations: Austin, London, Denver, or Lisbon

What you'll do

We’re looking for a Senior Software Engineer to join our WARP Edge service team. You will be working on our WARP service, which securely terminates tunnelled traffic from millions of devices running warp client, and uses Cloudflare’s global network to securely route the traffic. 

In your role, you will predominantly be using Rust to implement high-performance networking code that runs on linux. You’ll be expected to improve the code quality and to build solid, testable, and well-documented foundations. You will be most successful in this role if you have a good understanding of operating system concepts (virtual memory, multi-threading, process lifecycle, etc.) and networking protocols (TCP/IP, UDP, DNS, QUIC, H/3, proxying, etc.).

As a Senior Software Engineer, you will be expected to make significant contributions to the design and implementation of major development projects, working closely with our product managers and other teams to implement customer-impacting features. You will work on stimulating problems born out of the scale of our deployment, and the stringent quality, performance, and security requirements of our product.
