About Upstart
At Upstart, we’re united by a mission that matters: to radically reduce the cost and complexity of borrowing for all Americans. Every day, we bring creativity, experimentation, and advanced AI to reshape access to credit, helping millions move forward financially with clarity and confidence.
As the leading AI lending marketplace, we partner with banks and credit unions to expand access to affordable credit through technology that’s both radically intelligent and deeply human. Our platform runs over one million predictions per borrower using more than 3,000 signals, powering smarter, fairer decisions for millions of customers. But the numbers only hint at the impact. Every idea, every voice, and every contribution moves us closer to a world where credit never stands between people and their financial progress.
We’re proudly digital-first, giving most Upstarters the flexibility to do their best work from wherever they thrive, alongside teammates across 80+ cities in the US and Canada. Digital-first doesn’t mean distant. We’re intentional about in-person connection through team onsites, planning sessions, and moments that spark creativity and trust. And whether you choose to work primarily from home or collaborate in-person from one of our offices in Columbus, Austin, the Bay Area, or New York City, you’ll have the support to work in the way that works best for you.
If you’re energized by tackling meaningful problems, excited to innovate with purpose, and motivated by work that truly matters, we’d love to hear from you.
The Team
Upstart’s Infrastructure Security team is focused on securing the cloud, compute, platform, and deployment layers that run our products. We believe security should enable fast, safe delivery through strong engineering fundamentals, automation, and secure-by-default patterns. Our team partners closely with platform, infrastructure, SRE, product engineering, risk, and compliance teams to reduce risk in areas such as cloud IAM, Kubernetes and container security, network controls, secrets management, infrastructure-as-code, production vulnerability management, and AI-assisted developer workflows.
As the Principal Platform Security Engineer at Upstart, you will define and drive the technical strategy for securing Upstart’s production infrastructure and developer platforms. You will lead cross-functional and cross-organizational efforts to reduce systemic infrastructure risk, influence architecture and engineering roadmaps, and build durable security controls that scale across teams. This role is well suited for a senior technical leader who brings deep infrastructure security expertise, strong engineering judgment, and the ability to translate complex security risks into practical, high-impact improvements for the business.
