Requirements: - 2+ years of software engineering experience with hands-on development in C++ - Proficiency in one or more programming languages (C++, C#, Go, Python, or similar) - Familiarity with game engines, real-time systems, large-scale simulations, or entity component systems is a plus - Strong willingness to learn, take on unfamiliar problems, and stay current with evolving technologies - Ability to collaborate in cross-functional and cross-team projects to deliver curated technical solutions - Long-term mindset and willingness to take a long view to drive collaboration and build systems
