C programmers - Compiler Porting and Optimization

Location:

C programmers

This role emphasizes hands-on work with compiler behavior, runtime debugging, and performance tuning rather than extensive new code development. You’ll collaborate closely with engineering teams, gain client-side exposure, and contribute to the stability and optimization of large-scale enterprise database systems.

runtime optimization for AI-related workloads

Responsibilities

• Port large-scale database code between compiler toolchains on UNIX-based systems, identifying and resolving complex compile-time and runtime issues to ensure production stability.
  
• Analyze runtime behavior, identify bottlenecks, and collaborate with engineering teams to implement performance enhancements on advanced hardware architectures.
  
• For the AI runtime optimization role, enhance runtime performance for key compute functions using techniques like compiler tuning, vectorization, threading/parallelization, custom operation implementations, and numerical algorithm refinements.
  

Required Skills

• Exceptional troubleshooting skills (with or without a debugger) in large-scale, complex systems.
  
• Strong experience with

  C programming

  using compilers such as GCC, XL C, ICC, Clang/LLVM, or AOCC.
• Proficiency in

  system programming

  on UNIX/Linux, including memory management, threading, process control, and performance tuning.

Preferred Skills

• Hands-on experience with

  GDB

  for low-level debugging.
• Background in

  compiler development

  or contributions to open-source compiler projects.
• Understanding of

  compiler internals or behavior

  (experience with LLVM is a plus).
• Familiarity with

  C++, Java, JDK, and JVM

  .
• Experience with

  performance analysis tools

  such as Valgrind, Perf, Nmon, PMU, Nectar, or Pipestat.
• Experience with

  distributed or parallel applications

  .
• Exposure to

  AI, simulation, or numerically intensive algorithms

  used in modeling and performance computation.
