We are seeking a highly skilled Security Platform Engineer to join our team at Cloudflare. As a Security Platform Engineer, you will play a critical role in providing a secure infrastructure for one of the biggest online platforms in the world.

Key Responsibilities:

  • Build and manage the PKI that provides trusted certificates to all of our internal services with fine-grained authentication and authorization controls
  • Create and support robust client-side automation tooling to enable the use of short-lived certificates while maintaining reliability
  • Promote the use of strongly-authenticated mTLS for all service-to-service communications and work with other engineering teams to develop solutions for their use cases
  • Communicate and execute on periodic CA rotations and migration to best practices
  • Contribute to the strengthening of CA and leaf certificate key protection schemes to elevate our security profile

What We're Looking For

We're looking for a highly motivated and experienced Security Platform Engineer who has a deep understanding of PKI standards and their surrounding ecosystem. You should have experience running an internal or public PKI with a deep understanding of their requirements and pitfalls.

You should also have experience working with codebases and developing in Go or Rust. Familiarity with SPIFFE/SPIRE or other service identity framework/standards is a plus.
