Cloudflare Staff Software Engineer on Cloudflare’s Security Platform team building and operating secure, resilient distributed systems for secrets and key management. Focuses on internal PKI and machine/workload identity infrastructure.
Responsibilities
The Security Platform team is an infrastructure/developer tools group tasked with building and operating powerful, resilient, and secure infrastructure and systems that enable other engineering teams to deliver products to our customers efficiently and securely. We are responsible for secrets management, internal certificate authorities/PKI, machine and workload identity, and more. We are not a policy, audit, or compliance team, but rather an infrastructure engineering/software development one.
You’ll build and operate secure and resilient distributed systems for secrets and key management, running across our network that spans more than 310 cities in over 120 countries. Our focus is strengthening/re-architecting internal PKI and machine/workload identity. You’ll run and support the systems we build, both in an operational sense and by helping other internal developers use them. You’ll consult on the design and architecture of new systems and products to ensure they are built securely and use our services correctly.
This role may require flexibility to be on-call outside of standard working hours to address technical issues as needed.
