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 and the role:

This role sits within eBay’s engineering organization and is focused on building a next-generation AI-powered platform that transforms how software is designed, developed, and delivered at scale. Our Platform Engineering team builds and operates backend services that power intelligent workflows and developer-facing capabilities, enabling product teams across eBay to move faster while maintaining high quality and performance. As a Senior Software Engineer – Backend, you will architect and develop core platform services, solving complex technical problems and shaping scalable solutions for critical platform features. You will partner closely with engineers, product managers, and cross-functional teams, while mentoring junior engineers and contributing to an inclusive, learning-focused culture that values ownership, thoughtful collaboration, and sustainable work/life balance.

What you will accomplish:

Design, build, and evolve scalable backend services and APIs that power intelligent workflows and developer-facing capabilities, directly improving developer productivity and delivery speed.
Drive system architecture and technical decisions with a focus on performance, reliability, and maintainability, simplifying systems and reducing technical complexity where possible.
Own end-to-end delivery of features and services from design through production, upholding high standards for code quality, testing, and operational readiness.
Improve system performance, scalability, and efficiency by proactively identifying bottlenecks, strengthening observability, and effectively troubleshooting production issues.
Collaborate closely with product, data, and partner engineering teams to deliver impactful solutions, clearly communicating technical trade-offs, risks, and progress.
Mentor and support junior engineers, sharing knowledge, reinforcing engineering guidelines, and continuously adopting new technologies and approaches to raise the bar for the team.

What you will bring:

5+ years of professional software engineering experience, including building and operating backend systems in production and delivering features or services end-to-end.
Proficiency in one or more backend programming languages such as Java, Go, Python, or similar, with a solid understanding of distributed systems, microservices, and service-based architectures.
Hands-on experience with databases (SQL and/or NoSQL), APIs, messaging systems, and familiarity with cloud platforms (such as AWS, GCP, or Azure) and container technologies.
Strong system design, debugging, and problem-solving skills, with awareness of performance, reliability, and operational trade-offs in real-world environments.
Effective collaboration and communication skills, with experience working closely with product managers and cross-functional partners and explaining technical concepts to diverse audiences.
Experience with platform or developer tooling, AI/ML or workflow-based systems, and/or observability, monitoring, and production operations is a plus; role location and hybrid expectations to align with eBay’s local site guidelines.

C$118,000 - C$157,500

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