Senior Systems Engineer, SDKs, Terraform, & Code Generation

Cloudflare’s API Experience team builds the tools and standards that make our API dependable and easy to use. We maintain SDKs and our Terraform provider, build code generation tooling, and are developing API versioning.

We’re looking for a senior engineer who cares about the details developers live with: clear interfaces, predictable behavior, useful errors, and upgrades that don’t break their code. You’ll work across languages and teams, help internal engineers ship better APIs, and respond directly to customers. Their feedback will help shape what you build.

• Build and maintain our SDKs, Terraform provider, and the code generation tooling behind them.

• Develop API versioning and compatibility practices that let our API evolve without leaving customers behind.

• Improve API governance: consistent schemas, clear standards, and checks that catch problems before release.

• Support internal teams daily and work directly with customers to investigate issues and turn recurring friction into lasting improvements.

• Own projects from design through release and ongoing maintenance.

Desirable Skills, Knowledge, and Experience

• 5+ years of experience building large-scale software applications.

• Deep Go expertise, with experience building and maintaining production software.

• Fluency across languages such as TypeScript and Python, and an understanding of what makes a library feel natural in each.

• Experience building, maintaining, or contributing to a Terraform provider.

• Experience shipping SDKs or client libraries, including testing, releases, dependency management, and backward compatibility.

• Well-reasoned opinions about API design and developer tooling, paired with the ability to listen, explain tradeoffs, and make practical decisions.

• Strong technical judgment built through experience: you can untangle complex problems, set a clear direction, and lead projects from early design through delivery.
