Who we are About Bridge Bridge is Stripe’s fintech innovation hub focused on building a modern, stablecoin-powered cross-border payments network. We operate like a startup within Stripe: fast-paced, entrepreneurial, and product-obsessed, but with the backing of one of the most trusted names in fintech. We’re hiring a Security Engineer to build and scale Bridge’s security foundation. This is a rare opportunity to design a security program from the ground up, while also leveraging the infrastructure, best practices, and tooling of one of the most mature security organizations in the industry. What you’ll do Responsibilities Design, and implement Bridge’s security roadmap from first principles to production. Identify and tackle Bridge’s most important security risks quickly and pragmatically. Integrate with Stripe’s infrastructure where it makes sense, and find custom solutions where it doesn’t. Lead threat modeling and hardening efforts for Bridge’s money movement systems in collaboration with crypto and infra teams. Build key security capabilities (monitoring, secrets management, incident response, access controls, CI/CD hardening, etc). Reinforce engineering best practices around secure development and infrastructure. Ensure Bridge meets compliance and audit expectations as we scale to more regulated markets. Collaborate cross-functionally with engineering, product, and Stripe’s security org to move fast without compromising safety. About you You might be a good fit if you: Have 8+ years of experience in Security engineering, ideally with time spent in fast-paced startup environments where you’ve built security practices from the ground up. Have a startup mindset: you’re scrappy, pragmatic, and move quickly to solve the most critical problems. Are comfortable writing and debugging backend application code (Ruby is a plus, but not required). Thrive in ambiguity and know how to ruthlessly prioritize. Can balance security rigor with speed, especially in fast-moving environments. Communicate clearly across technical and non-technical partners. Have experience building or scaling security programs, either at a startup or in an embedded role. Are excited about the potential of crypto and stablecoins to power global financial infrastructure (you don’t need deep prior knowledge—just curiosity and openness to learn).
