About the Role
The OfferUp Business team owns the platforms that power every business vertical on our marketplace, including Storefronts, Auto Dealers, Services, Rentals, and Jobs. Our customers are running businesses on our platform, 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 RPS and TPS, and integrations with partners like Stripe and Shopify.
At OfferUp, you own a feature from concept to fruition. Your responsibilities include everything from writing well-architected, tested code to rolling out features by analyzing metrics. You will work with cross-functional team members to deliver high-quality solutions.
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 the 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 (Claude Code, Cursor, Copilot, and similar) to increase daily development velocity and code quality.
- Become a subject matter expert in one or more of the team's sub-domains.

- React, TypeScript, HTML, CSS, and modern web tooling; good grasp of responsive design, performance, and cross-browser compatibility.
- Java and a working understanding of microservices and distributed-systems fundamentals.
- Experience building and integrating with REST or GraphQL APIs.
- Good knowledge of data structures and object-oriented design.
- Hands-on experience using AI coding tools (Claude Code, Cursor, Copilot, or similar) in a real engineering workflow.
- Follows good coding patterns, writes appropriate tests, considers trade-offs, and actively seeks out edge cases.
- Comfortable giving and receiving feedback in code reviews.
