2. Low‑Level Performance Analysis and Optimization

• Profile and optimize CPU performance, memory usage, multithreading, and other low‑level engine systems.
• Identify and resolve performance bottlenecks through profiling, debugging, and code‑level analysis.
• Optimize engine runtime performance, compilation efficiency, and overall system stability.
• Develop practical optimization solutions based on performance measurements and technical analysis.

3. AI‑Assisted Development and Automation

• Leverage AI coding assistants and AI agents to accelerate coding, debugging, testing, and code maintenance.
• Explore and implement AI‑assisted workflows for code generation, code analysis, automated testing, and developer productivity.
• Develop automation scripts and tools to streamline repetitive engineering tasks and improve development pipelines.
• Evaluate the effectiveness, reliability, and maintainability of AI‑assisted engineering solutions.

4. Engineering Infrastructure and Technical Support

• Improve engine build systems, compilation workflows, and development infrastructure.
• Support technical debugging, engine integration, and cross‑platform development.
• Develop reliable tools and utilities to improve engineering efficiency.
• Create clear technical documentation and establish reusable engineering practices.

Qualifications:

1. Game Engine Development Experience

• Hands‑on experience with Unreal Engine 5 or other commercial game engines.
• Solid understanding of game engine architecture, runtime systems, and development workflows.
• Experience debugging, modifying, or extending game engine C++ code.
• Familiarity with game engine profiling and debugging tools.

2. Strong C++ and Systems Programming Skills

• Proficient in modern C++, with a strong understanding of memory management, multithreading, data structures, and algorithms.
• Solid knowledge of low‑level software systems and performance optimisation.
• Experience identifying and resolving CPU, memory, or multithreading performance bottlenecks.
