Backend Engineer, AI Security
Stripe is seeking a Backend Engineer for its foundational AI Security team. This role involves building security frameworks and defenses against AI-specific threats like prompt injection and jailbreaks, working closely with other engineering teams to secure Stripe's AI infrastructure and products. The ideal candidate will have 5+ years of software development experience and expertise in security engineering or AI/LLM-based systems.
AI is moving fast and Stripe is moving fast to adopt it. But we need to make sure we do all of this safely, and for most of these tools enterprise-grade security isn't just available off the shelf. That's where the AI security team comes in - we are responsible for building and partnering to create the right security primitives to enable Stripe to move fast safely.
This is a team that will be working in the low level components of our AI stack so both infrastructure and security experience are pluses. This space is moving fast so being comfortable with ambiguity and changes in priority are a must. This is a foundational role — you'd be the first engineer on the team.
Engineers on this team will do a mixture of partnering and advising with teams building AI infrastructure and products, and building security infrastructure primitives for AI. One of our major focuses will be building a security tooling layer that sits in the inference path, providing detection and protection against AI specific threats like prompt injection, jailbreaks, and tool misuse.
