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
Upstart’s Event Bus, Experimentation, and gRPC team is responsible for building frameworks and tooling to support Event Driven Architectures, safe and measurable roll out of new features, and efficient service to service communication. We do this by owning the build process and libraries for the four primarily supported languages at Upstart (Ruby, Kotlin, Python, and TypeScript). These platform products allow Upstart engineers to use them in a simple and secure way. Ease of use, performance, data quality, observability, and security are our guiding principles.
As a Senior Software Engineeron Upstart’s Event Bus, Experimentation, and gRPC team, you are empowered to design and implement high impact, cross cutting solutions that touch nearly every service within Upstart. We are a small and high impacting team contributing to Upstart’s North Star Architecture and need a product-oriented engineer who is excited to contribute across Event Bus, Experimentation, and gRPC internal tooling.
