Software Engineer, Secure Devices

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.

Secure Devices is responsible for ensuring that every client endpoint at Stripe adheres to our rigorous security standards. Our services play a crucial role in detecting and preventing data loss, restricting software execution to only approved software, and providing attestation capabilities to securely manage device identities. We operate both on-device and backend services across multiple platform types. Our users-first approach ensures that we’re empowering Stripes to be as productive as possible while protecting user data. 

As a software engineer on Secure Devices, you will work at the intersection of software development, security, and client platform engineering. You will work with teams across Security and Corporate Engineering to drive strategic projects to better secure Stripe endpoints, build infrastructure for supporting new platforms, and operate services critical to securing over 10,000 Stripe devices.

• Build and maintain a users-first data loss prevention program to protect against accidental and malicious data exfiltration.
• Design, build and maintain Stripe’s endpoint security software. This includes developing telemetry and prevention capabilities via macOS system extensions that run on all Stripe macOS devices.
• Collaborate closely with partner teams to define and measure the secure configuration of Stripe’s client platforms.
• Operate backend services providing critical controls and security configuration to Stripe endpoints.
• Drive down usage of unapproved, untrusted software while creating a surprisingly great user experience for onboarding new, approved software. 
• Manage and improve device attestation flows to ensure Stripe’s device and user identities are kept secure.
