What you’ll do

This role may require flexibility to be on‑call outside of standard working hours to address technical issues as needed.

Cloudflare is looking for a backend engineer on our control plane product platform to help us build our customer APIs and our internal service APIs. This is a role for engineers that are familiar with standard backend architecture, and capable in database design and interaction. Our API platform is under constant load and scrutiny, so experience and commitment to easily understood and tested code is also a key part of the role. Your ability to visualize the flow of data through a complex application is critical to your success, and to the team’s. You will be working closely with the product team to understand and document the functional needs of their product requirements, developing new code to solve new problems, as well as maintaining existing code to squash bugs. Our tech stack includes services built using Go, Redis, Postgres, and Cloudflare products (e.g. Workers). We’re looking for proficiency in RESTful API design, OpenAPI, Terraform, relational databases (SQL), and modern containerized deployment practices.

Examples of desirable skills, knowledge, and experience

• 7–10 years of professional experience building and managing software applications at large scale.
• Has managed or maintained Terraform providers (not just used them).
• Strong OpenAPI experience.
• Strong API design principles.
• Deep knowledge of Go with strong computer science fundamentals is a must.
• Experience in designing and architecting large‑scale distributed systems.
• Experience designing, implementing, and documenting customer‑facing APIs.
