Software Engineer II, Developer Platform

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 (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 Developer Platform team enables engineers to build, test, and validate software quickly, consistently, and with confidence. We own foundational systems and workflows engineers rely on before software reaches production, including build and continuous integration infrastructure, ephemeral environments, shared test infrastructure, and developer tooling.

Our goal is to make the path from code change to deployable software fast, reliable, and self-service. We build platforms that provide trusted feedback early, enable engineers to validate changes in production-like environments, and make common development and testing capabilities easy to adopt across engineering. We partner closely with Delivery, Cloud Platform, Site Reliability Engineering, Security, and product engineering teams to create a cohesive developer experience.

As a Software Engineer II, Developer Platform at Upstart, you will build and operate systems used by engineers across Upstart to develop, test, and prepare software for production.

Preferred Qualifications:

Experience with Kubernetes control-plane engineering, AWS, containers, or infrastructure as code

Knowledge of developer tooling, continuous integration systems, internal developer platforms, or shared test infrastructure

Experience building or operating ephemeral or production-like development and testing environments

Experience building APIs, services, command-line tools, test orchestration, or automation used by other engineers

Experience using AI-assisted development tools across the software engineering lifecycle or building AI-enabled developer workflows and automation
