Responsibilities
Port Oracle database code from IBM's XL to Open XL compilers on the AIX operating system, investigating and resolving complex compile-time and runtime issues to ensure production readiness
Optimize Oracle database performance on IBM Power architecture by analyzing runtime behavior, identifying bottlenecks and opportunities, and working with other Oracle engineers to implement effective solutions
For the ONNX role,
enhance ONNX Runtime performance on AIX to accelerate key ONNX functions invoked by the Oracle database. This involves applying techniques like compiler tuning, vectorization, threading/parallelization, custom operation implementations and numerical algorithm refinements.
Required Skills
Exceptional troubleshooting skills (with and without a debugger) in large-scale, complex systems
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
