About the team
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.
What you'll do
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.
Required skills
  • Software development and distributed systems design expertise.
  • 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).
  • Familiarity with HashiCorp Vault or OpenBao, or similar.
  • Linux/UNIX system administration proficiency.
  • Familiarity with Go and/or Python + Salt specifically
