The job involves developing low-layer modules and tool foundation technologies for game runtimes. As a systems engineer, you will provide stable foundational technology to engineers who develop game engines. This includes developing modules for the runtime and providing systems for tool development. Responsibilities include multi-platform support and maintenance of low-layer parts such as memory management and thread management, development and maintenance of data synchronization systems between runtime and tools, and development and maintenance of asset pipeline construction systems. Testing driven development methodologies are also to be promoted. This role is crucial for ensuring the stability and efficiency of game engine development.
