The role supports efficient application performance and seamless integration across the HPC stack.

Roles and Responsibilities

Middleware Stack Management

• Deploy, configure and maintain HPC middleware stack, which includes:
  • Scientific libraries and frameworks
  • HPC runtime environments
• Manage and support container engines for HPC workloads.
• Collaborate with HPC System and Storage Engineers to ensure middleware compatibility with OS, drivers, scheduler, and filesystems.
• Ensure middleware components comply with security policies.

Application Integration and Support

• Assist users in integrating domain-specific applications with middleware layers to ensure optimal performance and compatibility.
• Assist in tuning and troubleshooting through performance profiling and debugging.
• Provide technical guidance to users on middleware usage and best practices.

Designing and Planning

• Evaluate new middleware technologies and programming models.
• Contribute to middleware architecture design for future HPC expansions.

Qualifications

• Degree in Computer Science, Engineering, or related field.
• Minimum 3 years of experience in HPC environments, with focus on middleware or application integration.
• Proficient in Linux systems and CLI tools.
• Strong knowledge of MPI (Cray MPI, OpenMPI, MPICH), scientific libraries (Intel MKL, cuBLAS), and I/O libraries (HDF5, NetCDF).
• Experience with container technologies (Singularity,Enroot, Podman) and HPC programming suites (Intel OneAPI, NVHPC).
• Familiarity with RDMA-based interconnects (InfiniBand, RoCE) and parallel file systems (Lustre, GPFS, BeeGFS).
• Scripting skills in Python, Bash, or Perl.
• Strong analytical and troubleshooting abilities.
