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 in-person sessions’ cadence varies depending on the team and role; most teams meet once or twice per quarter for 2-4 consecutive days at a time.

 

How you’ll make an impact:

  • Architect and build software solutions (Workflows, Services, and internal tools) that accelerate security
  • Elevate security maturity across the organization by mentoring engineers, influencing leadership through clear risk metrics, and fostering a culture where security enables innovation
  • Continuously improve systems by learning from real-world signals such as false positives, operational feedback, and evolving threats

What we’re looking for: 

  • Minimum requirements:
    • Proven track record of owning security initiatives end-to-end, including post-launch validation, monitoring, and iterative improvement

    • Demonstrated ability to identify, investigate, and remediate complex security issues across one or more domains
    • Experience developing code and building services to enhance unique security needs 
    • Demonstrated ability to leverage AI-assisted tools (e.g., code generation, analysis, or investigation tools) to improve productivity while maintaining security and quality standards
  • Preferred qualifications:
    • Experience working with diverse data domains (e.g., analytics, reporting, business operations, or people data)
    • Experience assessing security risks in AI/ML systems (e.g., prompt injection, model misuse, data poisoning, access control around models)
    • Experience building applications hosted in a K8s environment
    • Experience with security orchestration tools for automating processes that are adopted beyond a single team
    • Experience partnering with Legal, Risk, Compliance, and Audit teams to operationalize security controls in regulated environments

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
