Software Development Engineer II Full Stack - Business (Remote @ Colombia)

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.

Responsibilities

• Design, build, and deploy new user experiences and backend services across our five business verticals, using React, TypeScript, GraphQL, Node.js, and Java
• Own features end-to-end: plan, design, develop, deploy, measure, and iterate
• Break down complex engineering problems into achievable tasks and deliver them within committed timeframes
• Work collaboratively with cross-functional teams (Product, Design, Data, Business stakeholders) to design and implement new features
• Contribute to A/B tests and use experimentation results to decide what ships
• Actively participate in code reviews and enforce good patterns, testing, and edge-case handling
• Coach and mentor junior team members, new hires, and interns
• Create shared components, utilities, and services that improve team velocity across the stack
• Maintain and improve runbooks, alerting, and monitoring for the features you ship
• Participate in a reasonable on-call rotation with the rest of the team
• Use AI coding tools to increase daily development velocity and code quality
• Become a subject matter expert in one or more of the team\'s sub-domains
