In this role, you will work on one of several Seller Hub work streams, including Orders, Listings, Acquisition, or cross-platform seller experiences. You will build and enhance seller-facing products with a primary focus on backend development, while also contributing to web experiences as needed.

This is a strong fit for an engineer who enjoys owning projects end to end, thrives in a collaborative environment, and wants to grow as a full stack engineer while working on high-impact products used across the marketplace.

• Design, build, and maintain scalable backend services and APIs that power key Seller Hub experiences
• Contribute to modern web applications that support intuitive, reliable seller workflows
• Partner closely with product managers, designers, and engineers across disciplines to deliver customer-facing features
• Lead projects independently from technical design through implementation, testing, rollout, and iteration
• Contribute to system design and architecture decisions for new and existing platform capabilities
• Write high-quality, well-tested code and help raise engineering standards across the team
• Collaborate across work streams as business priorities evolve and team needs shift

What You Will Bring

• Strong software engineering experience with deep backend development expertise
• Strong proficiency in Java, with hands-on experience building services using Spring Boot
• Experience designing and building scalable distributed systems, services, or APIs
• Frontend experience with modern web technologies such as React, Node.js, JavaScript, HTML, and CSS
• Ability to contribute across the stack, with a willingness to deepen expertise beyond a primary discipline
• Strong system design or architecture experience
• Demonstrated experience leading projects and driving delivery with a high degree of ownership
• Solid understanding of software design, testing, debugging, and engineering best practices
• Experience working in agile, collaborative engineering teams

Nice to Have

• Experience with Scala
• Experience building products at enterprise scale
• Experience working on customer-facing e-commerce or marketplace products

Why Join This Team

• Work on Seller Hub, a core eBay platform that directly impacts sellers across the marketplace
• Build across multiple problem spaces, including orders, listings, acquisition, and seller workflows
• Grow as a full stack engineer on a team that values cross-functional learning and flexibility
• Join a collaborative engineering organization with opportunities for ownership, mentorship, and technical impact

What You Can Expect From Us

• A collaborative, inclusive, and inventive work environment
• Managers and teammates who are invested in your growth as an engineer and as a person
• Opportunities to work on meaningful, high-scale products that serve a global marketplace
• Access to tools, resources, and learning opportunities to support your development

If you are a backend-strong engineer with full stack curiosity and a passion for building impactful seller experiences, we would love to meet you.
