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.

Location: Dublin, Ireland

Organization: eBay Application Platform – Frameworks Team

We’re looking for a Platform Engineer (API / GraphQL) to join the eBay Frameworks Team within our Application Platform organization.

You’ll help build, operate, and evolve our GraphQL Federation and the platform. Your work will ensure the federation and the APIs are scalable, reliable, and developer-friendly, enabling seamless experiences for eBay’s partners, sellers, and internal teams.

You’ll collaborate closely with teams in San Jose, CA, New York and Shanghai, contributing to a global platform that implements the GraphQL federation at eBay.

If you’re interested in building high-impact API platforms, shaping GraphQL infrastructure, and working on distributed systems that operate at global scale, this role is for you.

What you will accomplish

Design and build scalable, highly available services, including GraphQL gateways and federated schemas
Develop and operate GraphQL platform infrastructure, enabling teams to efficiently expose and consume data
Own production systems end-to-end: monitor, troubleshoot, and resolve API and notification issues
Improve GraphQL performance and reliability through query registration, optimization, caching, and observability
Keep platforms secure and up to date with dependency upgrades and vulnerability remediation
Automate operational workflows to reduce toil and improve system reliability
Write clean, maintainable Java code using Spring Boot and strong design principles
Partner with product and engineering teams to deliver scalable API.

What you will bring

3+ years of software engineering experience
Strong Java fundamentals with Spring Boot, OOP, and data structures
Understanding of GraphQL concepts such as schema stitching/federation, query optimization, and caching strategies
Experience with API design, including GraphQL and RESTful services
Experience with CI/CD pipelines (e.g., Maven, Jenkins)
Knowledge of Kubernetes and cloud-native deployments
Strong focus on reliability, scalability, and developer experience
Curiosity, ownership mindset, and passion for building platform capabilities used across large organizations
Experience in building or operating GraphQL APIs (e.g., schema design, resolvers, federation, or gateway architectures) is nice to have.
