About the Role
The OfferUp Business team owns the platforms that power every business vertical on our marketplace: Storefronts, Auto Dealers, Services, Rentals, and Jobs. Our customers aren't casually browsing; they're running businesses on top of what we build, so every feature we ship has a direct, measurable impact on their livelihood and on OfferUp's revenue. We operate the full stack end-to-end, including microservices that handle high request rates and integrations with partners like Stripe and Shopify. We move fast, instrument everything, and treat experimentation as a first-class part of the workflow. The roadmap is wide open for someone who wants to help shape it.
As a Full Stack Software Engineer II on the Business team, you'll be a proven contributor who ships features end-to-end across the stack, from the React components our business customers interact with to the Java services and data pipelines behind them. You'll take ownership of the work you deliver, raise the quality of the code around you, and grow into a high-performing, reliable contributor on the team.
