PsiQuantum is on a mission to build the first commercially useful quantum computer to solve humanity. Backed by Founders Fund and Redpoint.
About the role
As an HPC Software Engineer, you will be responsible for designing, developing, and optimizing HPC software solutions that leverage NVIDIA GPUs, AMD CPUs, and MPI for distributed and parallel computing. This role will require a strong foundation in computational science, parallel algorithms, and the specific intricacies of GPU and CPU optimization. Found on 1752vc Careers, the job board for startup and VC roles.
What they're looking for
- Education: Bachelor's or master's degree in computer science, Electrical Engineering, Computational Science, or a related field. Advanced degrees or relevant certifications are a plus
- Experience: 3+ years of experience in HPC development, with a focus on parallel and distributed computing, and experience with scalable systems. 5+ years previous experience in scientific software development
- Technical Skills: NVIDIA GPU Programming: Proficiency in CUDA and familiarity with NVIDIA’s HPC software stack, including cuDNN, NCCL, and TensorRT
- Parallel Programming: Expertise in MPI, OpenMP, and other parallel programming paradigms
- Cluster Scaling and Optimization: Strong understanding of scaling clusters and optimizing software for distributed, multi-node environments
- Languages: Strong proficiency in C/C++, Python, and Ansible / Terraform / Packer
More about this role
PsiQuantum's mission is to build the first useful quantum computers: machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.
Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry, including partners like GlobalFoundries, we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don't feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.
That approach has since been tested at the highest level of scrutiny the U.S. government applies to emerging technology, and it has held up. In 2025, PsiQuantum...
