Senior Software Engineer, Site Reliability

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 Site Reliability Engineering (SRE) team owns the reliability, resiliency, and observability of Upstart’s production systems. The SRE team builds tooling and automation to monitor the health of our infrastructure and create a fast, reliable, and productive environment for other engineers and a world-class experience for our customers. SRE defines Upstart’s strategy for technology operations risk mitigation, which includes disaster planning and on-call procedures. We use data-driven approaches to drive our decisions, and provide reports and insights to the business to improve visibility into the s ystem and customer experience. As a Senior Software Engineer focused on Site Reliability Tooling, your work will directly impact the success of the SRE team and all of Upstart. Your expertise will inform the team’s direction, and your work with other SREs and Upstart engineers will make Upstart’s systems as effective as possible for our customers.
