• Implement networking systems to stream Unity simulation state to external hosts under tight latency and bandwidth budgets • Build synchronization solutions including interpolation, prediction, and rollback when client and server run different simulation kernels • Optimize bandwidth through low-level serialization, delta-compression, and message dispatch schemes, optimized at the bit-level when necessary. • Diagnose and fix race conditions, desyncs, and jitter that arise when two engines disagree about reality under real-world networking conditions.

• Own and evolve critical subsystems across the engine stack, from low-level C++ to high-level C# APIs across editor, build, and runtime code. • Design and implement high-performance, extensible APIs intended for embedded, cross-process, and networked configurations. • Develop schemes to manage execution timing and resource contention within or between processes and over the network with minimal overhead. • Orchestrate loading, change tracking, serializing, and synchronizing components and assets in bandwidth and latency-constrained environments.
