The Security organization is dedicated to building and maintaining a secure financial infrastructure platform. By joining this team, you will be on the front lines, engineering solutions that protect the sensitive data and systems underpinning a huge portion of the world's economy. You will contribute to core security functions like threat detection and rapid incident response, building and scaling the platforms that manage vulnerabilities, and proactively performing offensive security assessments to identify weaknesses before they can be exploited. This is a chance to apply software engineering principles and new technologies such as AI to solve complex, high-stakes security challenges, ultimately ensuring that Stripe's mission to increase the GDP of the internet is achieved securely. What you’ll do As a Security Engineer New Grad you will have the opportunity to work across various security disciplines and own projects from start to finish. Your work will focus on securing Stripe's complex environment by applying software engineering principles to security challenges.

• You’ll develop a foundational understanding of various security domains, such as threat detection, incident response, vulnerability management, or offensive security.
• You’ll learn to act as a security subject matter expert, tailoring answers to both engineers and non-engineers.
• You’ll contribute to the development of internal tools and automation to scale security efforts across Stripe.
• You will participate in threat modeling discussions, learning to balance security requirements with product advancement and user experience.
