StubHub International (SHI) is a marketplace that provides fans a safe, transparent, and trusted environment to buy and sell tickets for sport and music events all over the world. It allows fans with tickets they can no longer use to recoup part of the money they’ve spent and fans that didn’t have the chance to buy tickets during the on-sale, to access them at any time. We are looking for a talented and motivated Backend Software Engineer to join our Engineering team (full remote). As a mid-level engineer, you will be a key contributor to the design, development, and evolution of our backend platform — a distributed, high-throughput system that powers the StubHub International marketplace.
You will work closely with fellow engineers, product managers, and designers to build robust, scalable services, participate actively in the full software development lifecycle, and contribute to the wider Backend Engineering Guild. This is a role for someone who takes pride in the quality of their work, operates with a good degree of autonomy, and is eager to grow alongside a high-performing team.





Design, develop, test, and maintain backend microservices using Java and/or Kotlin, following established engineering best practices.
Build and maintain event-driven integrations using Apache Kafka, including producer and consumer implementations, schema management, and stream processing patterns.
Participate actively in the full software development lifecycle: requirements analysis, technical specification, system diagramming, refinement sessions, and acceptance criteria definition.
Contribute to the Backend Engineering Guild — sharing knowledge, promoting best practices, participating in technical discussions, and helping to raise the engineering bar across the organization.
Write high-quality unit, integration, and contract tests, treating test coverage as a first-class engineering concern.
Engage with AI-assisted development tools and processes, incorporating them where appropriate
