Diagnose and resolve technical issues across C#, C++, and internal tools.
Collaborate with cross-functional teams to improve asset pipeline tooling and runtime systems.
Work on system profiling, debugging, and performance tuning.
Support CI/CD efforts including build capacity management, automated testing, and incident response.
Act as a generalist engineer with the ability to operate across multiple technologies and domains.

Requirements:

Strong software development experience in C# and Unity.
Experience with C++ and familiarity with performance profiling and system diagnostics.
Experience debugging complex systems and optimizing runtime environments.
Familiarity with CI/CD concepts such as build pipelines, alerts, and automation.
Proficiency in tools such as Phabricator, Sandcastle, Buck, or similar.
Experience with SQL and data analysis workflows.
Working knowledge of Python or other scripting languages is a plus.
Exposure to mobile platforms, particularly Android, is beneficial.
Bonus: Experience with build systems like Bazel or Buck, and code coverage tools.
