Hiring for a VC Backed Deep Tech Startup
About This Role
We are seeking a highly motivated HPC Performance Profiling Intern to join our High-Performance

Computing (HPC) team. The intern will focus on CPU/MPI/GPU performance profiling and

optimization for our advanced HPC simulation and optimization frameworks. This role is critical to

addressing current performance bottlenecks and ensuring scalability for production-level workflows.

The selected candidate will gain exposure to cutting-edge HPC applications, profiling tools, and

parallelization paradigms (OpenMP, OpenACC, CUDA, SYCL), while working closely with senior HPC

engineers on both in-house code and third-party integrations.

Key Responsibilities

  • Conduct strong- and weak-scaling analyses for complex HPC workloads.
  • Perform in-depth profiling of codebases to identify performance bottlenecks across CPU, GPU, and MPI/OpenMP layers.
  • Utilize profiling tools such as Nvidia Nsight Compute, Intel VTune, Intel MPI Profiler, mpiP, and Scalasca for detailed performance analysis.
  • Contribute to the design and implementation of a performance testing and monitoring framework for HPC workflows.
  • Prepare roofline plots, occupancy heat maps, and other performance visualizations for reporting and decision-making.
  • Collaborate with the HPC team to optimize application performance and improve code efficiency.
  • Support the creation of technical reports, white papers, conference presentations, and journal publications based on profiling findings.

Required Qualifications

  • Strong programming skills in C++.
  • Proficiency with MPI and OpenMP for parallel programming.
  • Hands-on experience with CUDA for GPU programming.
  • Strong analytical skills with the ability to interpret and visualize performance metrics.

Preferred / Good-to-Have Skills

  • Familiarity with performance profiling tools: Nvidia Nsight Compute, Intel VTune, Intel MPI Profiler, mpiP, Scalasca.
  • Knowledge of scaling concepts (strong/weak scaling), roofline modeling, and HPC performance visualization techniques.
  • Exposure to technical writing such as reports, white papers, or academic articles.
  • Background in HPC research, computational sciences, or applied mathematics.
