Original job description

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.

About the team

We’re building a new integration team in Toronto focused on bringing core eBay capabilities into adjacent marketplace platforms. The team sits at the center of a strategic initiative to deliver marketplace capabilities such as identity, demand generation, payments, and shipping as reusable services, with the potential to expand across additional platforms over time.

Role overview

This is a highly hands-on technical leadership role for an experienced backend engineer who can define architecture, write production code, and drive execution in a fast-moving, ambiguous environment. You’ll lead the technical direction for key platform integrations, partnering closely with engineering teams across multiple stacks and geographies while staying deeply involved in implementation.

Key competencies & responsibilities

Lead the technical architecture for a marketplace integration team, from early concept through implementation
Write and ship production code; this role is expected to be heavily hands-on
Drive architectural discussions, design reviews, and PR reviews across integration workstreams
Translate ambiguous business or product goals into clear, scalable technical solutions
Partner closely with engineering teams to integrate services across distinct platforms and tech stacks
Help define how eBay capabilities can be exposed as services for other platforms and future integrations
Influence engineering best practices around system design, maintainability, and long-term scalability

Must-have requirements

Strong hands-on backend engineering experience in Java
Proven ability to lead technical architecture and make sound system design decisions
Experience building or integrating distributed systems and service-based architectures
Strong communication skills and the ability to collaborate effectively across teams
Comfortable operating in ambiguity and forming a clear technical point of view with incomplete information
Strong individual contributor mindset with a desire to grow as a technical leader rather than a people manager

Nice-to-have requirements

Experience with GraphQL, especially federated graph architectures such as Apollo
Experience with Scala, Kotlin, or other JVM languages
TypeScript and/or Node.js experience
AWS or other cloud infrastructure experience
Familiarity with full-stack or web architecture
Experience in startup, scale-up, or other high-ambiguity environments
Experience in marketplace, commerce, or platform-as-a-service style companies

Why this role is interesting

Greenfield team with meaningful architectural ownership
High visibility work tied to eBay’s broader platform integration strategy
Exposure to multiple modern tech stacks across enterprise and cloud-native systems
Strong growth potential as this pattern expands to additional platforms and future integrations
Opportunity to join a growing Toronto engineering presence with significant local investment
