At eBay, we're more than a global ecommerce leader - we’re changing the way the world shops and sells. Our platform empowers millions of buyers and sellers in more than 190 markets around the world. We’re committed to pushing boundaries and leaving our mark as we reinvent the future of ecommerce for enthusiasts.

Our customers are our compass, authenticity thrives, bold ideas are welcome, and everyone can bring their unique selves to work - every day. We're in this together, sustaining the future of our customers, our company, and our planet.

Join a team of passionate thinkers, innovators, and dreamers - and help us connect people and build communities to create economic opportunity for all.

The Role

We are looking for a Sr. Full Stack Engineer - MTS 1 to join eBay’s Seller Hub team in Toronto. Seller Hub is eBay’s central seller-facing platform, supporting critical experiences that help sellers manage and grow their businesses.

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.

What You Will Do

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.

C$142,400 - C$190,100

Base pay offered may vary depending on multiple individualized factors, including location, skills, and experience.
