Senior Infrastructure Engineer

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 The Data Platform Engineering team (Part of Upstart's Decisioning & Data) provides developer tools, frameworks, and scalable data infrastructure as shared services across Upstart. The team's primary objective is to provide Data Analysts, ML scientists, and Software Engineers access to high-quality data and developer tools to create business metrics and training data for respective product verticals. You will join the Data Production Experience (PX) team, which owns Upstart’s Lakehouse (Databricks) infrastructure.

This is the platform that Machine Learning, Analytics, and Software Engineering teams use to build the training data and metrics behind our lending, fraud, and pricing models—enabling growth and reducing risk across our business verticals. As a Senior Infrastructure Engineer joining this team, you will focus on: - Lakehouse Infrastructure and Security : Own the Databricks platform across multiple environments, including a newly launched regulated environment (Upstart Bank). Responsibilities include expanding infrastructure as code for new Lakehouse features, enforcing a no-click-ops policy, establishing disaster recovery, implementing least-privilege and attribute-based access controls (e. g. , based on data classification), ensuring environment isolation, and resolving other known security risks. - Compliance : Close control gaps and automate evidence gathering for OCC, SOX and SOC audits across access management, change management, and data quality. - Cost and usage efficiency : Reduce Databricks and AWS spend through accurate cost attribution, waste detection, and platform-level optimizations (e. g. , compute rightsizing, improving pruning, migrating to Graviton and spot instances, Delta Lake Archival). How you’ll make an impact - Evaluate and adopt new technologies, including open-source lakehouse alternatives, to expand platform capabilities. - Improve developer efficiency and infrastructure reliability by working with cross-functional stakeholders like Data Engineering, Machine Learning, Analytics, Compliance, and Security. - Improve Lakehouse security, usage efficiency, and observability by collaborating closely with the Data Engineering and Security teams. - Evangelize good coding and engineering best practices while uplifting fellow engineers and mentoring junior team members.
