Senior Systems Engineer - Orpheus / Argo Smart Routing

Remote US
Software Development

Available Locations: US Remote, Canada, Mexico City

What You’ll Do

The Orpheus team was formed to own a very important aspect of Cloudflare's systems: enable more reliable network connectivity for Cloudflare’s products than the Internet itself provides.

Almost all products in Cloudflare’s portfolio are or will be powered by Orpheus technology, including CDN, Spectrum, Magic Transit, Stream, Workers, Workers AI, R2, WARP, and more. As a member of the Orpheus team, you’ll be a key technical contributor to the cutting edge network software infrastructure used by those products.

You will work closely with various Engineering teams to translate their requirements into new capabilities on the platform. Likewise you will partner with Network Engineering and SRE to ensure that the technology makes the best use of Cloudflare's world-class edge network.

You will participate in all stages of the software development lifecycle, from designing and documenting systems, to writing code and automated tests, to planning, managing, and monitoring production software deployments. You will work with a wide range of technologies and programming languages, including Rust, Go, Linux networking, ClickHouse, PostgreSQL, Grafana, Kubernetes, and more.

Engineering teams at Cloudflare operate a Run What You Build model, including ours. We are responsible for the health of our system and participate in our team's on-call rotation as part of operational responsibilities.

Because you’ll be solving problems of massive scale and significance, you are a growth-oriented individual who enjoys being outside of your comfort zone. You are comfortable in a fast-paced but sensible work environment. You value curiosity and empathy and lead with these values.
