You will play a pivotal role in this process.
You Will:
• Contribute to the design and development of programming models that improve script performance and scalability
• Develop prototypes to validate designs against realistic use cases, ensuring they meet our performance and functionality standards
• Take ownership of new feature development from concept and prototyping through to deployment and maintenance
• Improve the adaptability and performance of existing components
• Collaborate with engineers across engine and partner teams to build collaborative solutions
You Have:
• Over 10+ years of experience developing and deploying user-facing software products
• A minimum of Bachelor's degree in Computer Science
• Proficiency in C++ and an understanding of parallel/concurrent programming concepts
• Experience with API and tool development, game development, distributed systems, and Lua/Luau programming is a plus
• A grasp of industry standards and design patterns
• The ability to analyze and approach problems from multiple perspectives, weighing the advantages and drawbacks of different solutions
You Are:
• Enthusiastic about crafting software programming environments for game developers, eager to apply insights from multiple programming ecosystems to our scripting environment
• Self-driven, able to navigate complex codebases with minimal guidance
• Reliable, developing systems that are not just effective but also resilient over time
• Inquisitive, constantly learning and staying on top of the latest trends in scripting languages and programming environments
