Solid experience with C programming using compilers such as GCC, XL C, ICC, Clang/LLVM, AOCC
Proficiency in system programming in UNIX/Linux, including memory management, threading, process control,



and performance tuning

Preferred Skills
Hands-on experience with GDB for low-level debugging
Compiler development experience or contributions to open-source compiler projects
Understanding of compiler internals or behavior (LLVM experience is a plus)
Familiarity with C++, Java, Java Development Kit (JDK), and Java Virtual Machine (JVM)
Performance analysis/tuning with tools like Valgrind, Perf, Nectar, PMU, Pipestat, Nmon
Distributed or parallel application experience
Experience with ONNX or numerically intensive algorithms used in AI, simulation, or modeling
