Software Engineer, Secrets Infrastructure

About the role

About Stripe Stripe is a financial infrastructure platform for businesses. Millions of companies-from the world's largest enterprises to the most ambitious startups-use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone's reach while doing the most important work of your career. The Secrets Infrastructure team provides the cryptographic identity and secrets management foundation for Stripe. We build and operate the internal certificate authority that authenticates every person and service at Stripe, and the secrets platform that manages everything from financial partner credentials to infrastructure access keys. We build foundational security infrastructure at scale: our certificate authority issues mTLS client certificate identities for thousands of services and engineers, and our secrets platform and libraries protect access to critical financial systems and external partners across all of Stripe's codebases, services, and platforms. The technical challenges include building systems with 99.99%+ availability, implementing TLS workload identity and attestation logic for new platforms, and designing secret management tools that are both secure and user-friendly. Our infrastructure must be both reliable and developer-friendly-we maintain libraries in Go, Java, Ruby, and Python. As a small team responsible for critical systems, engineers take on meaningful ownership. Through collaboration with teams across Stripe, you'll build and set direction for the authentication and secrets management underpin identity in distributed systems at scale. Secrets Infrastructure is a fully remote team, with a small presence in the Seattle and New York City offices. We pride ourselves on a friendly, technically rigorous, and supportive team culture.
