Job description

Upstart is the leading AI-powered lending marketplace, helping banks and credit unions expand access to fair and affordable credit. Through our AI platform, lending partners achieve higher approval rates with lower losses — across demographics — while giving borrowers a fast, digital-first experience. Over 80% of our loans are approved instantly, requiring no document uploads.

We’re a digital-first company, meaning most Upstarters work remotely across the U.S., supported by collaborative hubs in San Mateo (CA), Columbus (OH), and Austin (TX).

Our mission is simple yet powerful: to enable effortless credit based on true risk. If that resonates with you — and you want to help build financial products that make a real difference — we’d love to hear from you.

The Opportunity:

Join the Home Lending engineering team to help design, build, and scale Upstart’s newest products: HELOC and Mortgage. This is a chance to shape two of the company’s most exciting initiatives — products built to unlock home equity for millions of Americans seeking smarter, faster, and more affordable financing for renovations, debt repayment, or major purchases.

We’re tackling a massive opportunity: enabling credit access for customers who’ve been overlooked by traditional lenders. Using machine learning and automation, we’re delivering lending experiences that are faster, fairer, and more inclusive.

What You’ll Do:

As an engineer on this team, you’ll work across the full stack, collaborating closely with product managers, designers, and fellow engineers. You’ll help shape product direction while shipping high-quality, reliable software that directly impacts customers.

• Building new features and services for Upstart’s Home Lending products using Kotlin, AWS, Kafka, Spring Boot, and Kubernetes.
• Proactively identifying improvements beyond your assigned tasks — from architecture to process optimization.
• Turning routine development work into opportunities to level up code quality and product scalability.
• Engaging deeply with product requirements and proposing smarter technical solutions when trade-offs are needed.
• Driving measurable improvements in performance, reliability, and customer experience.
• Contributing to the team’s culture of quality, innovation, and continuous learning.

What We’re Looking For:

Minimum Qualifications:

• 4+ years of professional experience with Kotlin, Java, or C# (we use Kotlin, but Java/C# expertise transfers well).
• Solid experience with SQL databases and domain modeling.

Preferred Skills & Attributes:

• Excellent communication skills — you can clearly explain technical concepts to both engineers and cross‑functional teams.
• Enjoy both asynchronous and synchronous collaboration; comfortable with regular video sessions (e.g., mob programming) in a distributed team.
• Confidence to challenge ideas respectfully — you’re empowered to speak up when something doesn’t feel right.
• A sense of ownership — you think like an engineer and a stakeholder.

Work Environment & Travel:

We’re remote‑first, but our team values in‑person connection. Expect quarterly onsite meetups (about three days each) in one of our main offices: Columbus, Austin, or San Mateo. All travel costs are covered by Upstart.

What You’ll Love About Working Here:

• Competitive pay (base, bonus, and equity).
• Comprehensive benefits – medical, dental, vision, and HSA contributions.
• 401(k) with 100% company match (up to $4,500).
• Employee Stock Purchase Plan (ESPP).
• Life & disability insurance.
• Generous time off – vacation, holidays, sick leave, and safety leave.
• Parental, family care, and military leave programs.
• Annual wellness and tech stipends.
• Inclusive culture – ERGs, book clubs, fitness groups, volunteering opportunities, and more.
• Catered lunches and snacks in‑office.

Why You’ll Thrive Here:

At Upstart, we celebrate curiosity, empathy, and first‑principles thinking. We value engineers who question assumptions, push boundaries, and build with purpose. If you’re energized by solving tough problems alongside smart, mission‑driven teammates — this is where you’ll do your best work.
