HPC Engineer

HPC Engineer(L2) with Application Expertise

Role Overview :

An L2 HPC (High-Performance Computing) Engineer with an application skillset is responsible for supporting, troubleshooting, and maintaining HPC infrastructure and assisting users with scientific and engineering applications. They operate between infrastructure and application layers, ensuring optimal performance and availability of both.

Core Responsibilities :

HPC Cluster Support :

Manage day-to-day operations of HPC clusters (Slurm, PBS, LSF), monitor jobs, and node health, and manage user issues at L2.

Application Support & Optimization :

Support scientific / engineering applications (ANSYS, Gaussian, GROMACS, OpenFOAM, etc.) including installation, configuration, tuning, and parallel execution optimization (MPI / OpenMP).

User & Job Management :

Handle user access, and environment setup (modules, environment variables), and resolve job scheduling issues.

Performance Monitoring :

Use tools like Ganglia, Prometheus, or Nagios to monitor cluster and job performance.

OS & Middleware Maintenance :

Perform updates and patching of OS (Linux / RHEL / CentOS), compilers (Intel, GNU), and libraries (MPI, BLAS, CUDA).

Collaboration :

Work with L3 / engineering teams for complex issues and contribute to environment upgrades or migrations.

Working Days : 6(Mon-Sat)

Key Skill Areas : HPC Environment :

Slurm, PBS Pro, LSF, Bright Cluster Manager

OS & Shell :

Linux (RHEL / CentOS), Bash scripting

Compilers & Libraries :

Intel, GCC, OpenMPI, MPICH, CUDA

Applications :

ANSYS, Abaqus, Gaussian, GROMACS, MATLAB, OpenFOAM

Monitoring Tools :

Ganglia, Nagios, Prometheus

Job Scheduler Debugging & Logs Analysis

Basic Networking & Storage Concepts

Software Module Systems (Lmod / Environment Modules)

Preferred Experience :

4–6 years in HPC environments

Exposure to GPU workloads

Understanding of parallel computing fundamentals

Ability to interact with application end-users and researchers
