Job Description:
About the role
We’re looking for a Java backend developer to join our Catalog Games team and help build and improve the technology behind our games.
You’ll develop game features, services, tools, and systems while collaborating with people across different disciplines. You’ll contribute throughout the lifecycle of our backend systems, from design and implementation to testing, deployment, monitoring, and ongoing improvement.
We’re looking for a mid-level developer who enjoys solving challenging technical problems and is comfortable working with large-scale, real-time systems and established codebases. You’ll take ownership of complete features or components, work autonomously, break work into manageable tasks, and balance delivery speed with quality, maintainability, and reliability.
Your Role Within Our Kingdom
You’ll work as part of a highly capable, collaborative team developing systems that improve game development and support features across Catalog Games’ titles. You’ll help deliver reliable, maintainable technology that supports great player experiences.
Our tech team serves as a central hub for game development. You’ll contribute to shared platforms, tools, and Java server frameworks, while working with teams across the organization. You’ll communicate progress, plans, risks, and problems clearly; contribute to technical decisions; support production services; and help improve our documentation, processes, and ways of working.
At Catalog Games we value ownership, curiosity, teamwork, continuous improvement, and a healthy balance between work and life.
