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 to improve delivery speed and code quality.





Communicate clearly and concisely — both verbally and in writing — with technical and non-technical stakeholders across geographies. Solid professional experience with Java as a primary backend language (preferable); Kotlin experience is valued. Practical experience with event-driven architectures, ideally using Apache Kafka or Confluent Platform — producer/consumer patterns, offset management, consumer groups, topic design, etc.

Solid grounding in software engineering best practices: design patterns (SOLID, DRY, CQRS, etc.), A culture of quality in testing: confident writing unit tests and familiar with integration and contract testing approaches. GitHub Copilot, AI-assisted code review, LLM-based developer tooling) and an openness to adopting AI workflows as part of the engineering process. Comfortable with version control workflows (Git, PRs, branching strategies) and CI/CD pipelines.

Capable of taking ownership of well-scoped tasks and features end-to-end, from design to production, with limited supervision. Consistently delivers well-tested, well-reviewed, and well-documented code; treats quality as non-negotiable, not an afterthought. Shares learnings and perspectives within the Backend Engineering Guild; English — conversational and written fluency required.

You will communicate daily in English with a geographically distributed team, write technical documentation, and participate in meetings and async written threads. Spanish — a plus but not required for the role.

Experience with Spring Boot or similar Java/Kotlin frameworks. Familiarity with cloud platforms (AWS, GCP, or Azure) and containerization (Docker, Kubernetes). Knowledge of SQL and/or NoSQL databases (PostgreSQL, MySQL, MongoDB, Redis). Contribution to open-source projects or technical community engagement (blog posts, conference talks, etc.). Versátil work that fits into your life. Permanent contract. Cultural diversity and international teams.

Other perks: private medical insurance, life insurance, pension plan, meal tickets, time off and other benefits.
