About the Role

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.

Responsibilities

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 will participate in the On Call rotation for emergency incident response. You’ll consult on the design and architecture of new systems and products to ensure they are built securely and use our services correctly.

Required skills

• Software development and distributed systems design expertise.
• Linux/UNIX system administration proficiency.
• Strong security background with a focus on implementation, not policy/compliance.

Bonus/nice-to-have skills

• Track record of contributing to open source security or distributed systems projects.
• Cryptography background and ability to work with cryptosystems at the primitives level.
• Experience with HSMs, TPMs, or other platform TEEs (e.g. AMD SEV, Intel SGX, Apple Secure Enclave).
