About this role

This role develops and improves core business web applications that support workflows outside game development. The engineer works with internal users to identify underlying needs rather than simply implementing requests, then translates those needs into system designs and useful functions.

The role also includes sharing technical knowledge through study sessions, documentation, and sharing information about new technologies.

Required qualifications include at least three years of experience designing and developing web application systems, an understanding of modern web application architecture with the ability to make appropriate decisions, and knowledge and operational experience related to DevOps required for web application development.

Experience operating systems using PHP, Python, Go, or TypeScript is welcome. Development experience using AWS, GCP, or Azure, and development or operations experience using Docker, are also welcome.
