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.

Senior Backend Software Engineer

About the team:

Authenticity Guarantee is an important initiative at eBay where a select category of items are authenticated by professional authenticators to increase buyer confidence and satisfaction. The Authentication Technology team is responsible for building software for orchestrating the authentication process and storing high-value items. The team is also responsible for building software for warehouse operations, including integration with custom hardware, RFID readers, and Android-based mobile devices.

About the role:

We are seeking a talented and motivated Senior Backend Software Engineer to design, develop, and maintain the core services that power our authentication platform. In this role, you will lead the architecture of distributed systems, ensure high availability and performance, and drive operational excellence through cloud-native best practices. You will work closely with product managers, cross-functional engineering teams, and DevOps to deliver robust, scalable solutions on Google Cloud Platform.

Responsibilities:

System Design & Architecture: Define, design, and implement complex, multi-tier distributed software systems. Participate/lead architectural discussions and produce high-quality design documentation.
Backend Development: Develop and maintain scalable, high-performance services using Java/Spring Boot. Create and evolve robust RESTful and GraphQL APIs for internal and external integrations.
Cloud & DevOps: Lead the deployment of services on Google Cloud Platform (GCP). Implement and maintain CI/CD pipelines (e.g., GitHub Actions, Cloud Build) and embrace Infrastructure-as-Code (IaC) principles.
Operational Excellence: Improve system reliability, observability, and performance. Troubleshoot production issues and participate in incident management.
Leadership: Mentor junior team members, conduct rigorous code reviews, and drive engineering standards across the team.

Required Qualifications:

Experience: 6+ years of advanced software development experience (or 5+ with a Master’s degree or equivalent professional experience) in building large-scale distributed systems.
Core Backend Expertise: Deep expertise in Java/J2EE and Spring Boot. Solid understanding of object-oriented design, design patterns, and caching mechanisms.
API Proficiency: Extensive hands-on experience designing and developing APIs using REST and GraphQL.
Cloud & Data: Proven experience working in a distributed cloud-native environment (GCP preferred). Strong knowledge of relational and NoSQL database design, data modeling, and performance tuning.
Engineering Practices: Proficient in professional software engineering practices, including CI/CD, automated testing (unit/integration), source control (Git/GitHub), and code quality standards.

Nice to Have:

Experience with containerization and orchestration (Docker, Kubernetes/GKE).
Familiarity with event-driven architectures and distributed processing.
Experience with infrastructure automation and monitoring tools (Cloud Monitoring, Logging, Terraform).
Understanding of warehouse operations, logistics, or high-value item authentication.
Basic familiarity with front-end technologies (React) if needed for cross-team collaboration.

The base pay range for this position is expected in the range below:

C$118,000 - C$157,500

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