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 1,800 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 (opening Summer 2026), 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

Lead the design and development of scalable, high-performance services that enable real-time pricing decisions across multiple products.
Collaborate with data scientists and product managers to translate business goals into robust technical solutions.
Drive architectural improvements in the pricing platform to support rapid growth, new products, and evolving modeling needs.
Mentor and coach engineers across the team, elevating best practices in system design, testing, and operational excellence.
Ensure the quality and reliability of our pricing engines through comprehensive testing, code reviews, and production monitoring.
Champion improvements in developer experience, automation, and observability to increase team velocity and platform resilience.

Excellent communication skills, able to explain complex technical topics to both technical and non-technical audiences.
Demonstrated experience mentoring and coaching engineers, influencing technical direction, and raising the bar for the team.

History of thriving in diverse work environments: both collaborative and self-directed; remote and in-person.
Deep experience with distributed systems, cloud-native development, and advanced CI/CD pipelines (infrastructure-as-code focus).
