Job Summary

PsiQuantumsmission is to build the first useful quantum computersmachines 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 approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industryincluding partners like GlobalFoundrieswe use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdontfeel heat are immune to electromagnetic interference and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024PsiQuantumannounced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane Australia and Chicago Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically definingand that now is the time to scale.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application software and industry teams work directly with leading Fortune 500 companiesincluding Lockheed Martin Mercedes-Benz Boehringer Ingelheim and Mitsubishi Chemicalto prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shiftand a path to mastering challenges that cannot besolvedany other way. The potential is enormous and we have a clearpathto make it real.

Come join us.

Team Overview

PsiQuantums Applications Software Engineering Team builds tools for quantum algorithm developers: cloud development environments circuit design tools and resource estimation systems that help researchers write simulate and optimize quantum algorithms for the worlds first utility-scale fault-tolerant quantum computer.

Were hiring a platform engineer who bridges software infrastructure with GPU-accelerated computing someone who can improve our AWS platform while helping researchers run quantum simulations efficiently on GPU clusters.

Role Overview

Were looking for someone to partner with our existing platform engineer splitting responsibilities across a growing platform and making it easier for quantum researchers to do their best work.

That platform includes AWS infrastructure Terraform configs CI/CD workflows and the GPU clusters our researchers depend on for large-scale computationally intensive quantum simulations. Theres a real opportunity to shape how all of it evolves.

The right person for this role is comfortable making judgment calls under uncertainty; they will have a lot of latitude and accountability to match.

Responsibilities:

How Youll Spend Your Time

Platform Engineering (70%)

Own our AWS infrastructure end-to-end and actively shape how it evolves; building not just maintaining.
Reduce friction in the deployment pipeline so developers can ship without infrastructure blockers.
Harden systems with intention: lock down IAM roles container images and authentication flows in ways that reflect a clear understanding of where the real risks are.
Implement monitoring and alerting that catches production issues before users notice them.
Make deployments faster to roll out easier to roll back and less prone to failure.
Lead incident response and post-mortems when necessary.

GPU/HPC Bridge Work (30%)

Make GPU clusters and other infrastructure invisible to the researchers running it.
Own CUDA compatibility and driver versions across heterogeneous GPU clusters.
Build standardized SLURM job submission workflows that researchers can use without help.
Package and containerize Python simulation code for reproducible execution.
Monitor job health across utilization cost and runtime efficiency.

Experience/Qualifications:

Required Qualifications

Experience: 5 years in Platform Engineering DevOps or SRE roles.
Production AWS experience: Built and maintained systems on ECS/EKS managed multi-account networking (VPCs security groups) and dealt with real-world infrastructure complexity.
Infrastructure as Code: Youve written and maintained Terraform (or Pulumi/CDK) in production including applying ongoing changes as requirements evolved.
CI/CD: Improved build pipelines in production (reduced build times increased reliability made deployments easier to debug) including experience with GitLab CI GitHub Actions or equivalent.
GPU/HPC experience: Supported GPU workloads in production environments including code optimization CUDA debugging and job scheduler setup.

Preferred Qualifications

Background in scientific computing research infrastructure ML platforms or early-stage startups (especially research computing vendors).
Security & compliance experience: Youve implemented auth systems (Auth0/Okta) managed encryption (KMS) or worked on FedRAMP/compliance-driven infrastructure. FedRAMP experience is a strong plus.
Exposure to quantum computing SDKs (Qiskit Cirq PennyLane) or hybrid classical-quantum workflows is a plus but not required; genuine interest in quantum computing matters more than prior exposure.

What Were Not Looking For

Candidates focused on enterprise-scale batch computing rather than cloud-native platform engineering.
Platform engineers without exposure to GPU workloads or HPC concepts.
Candidates who prioritize architectural purity over iterative delivery.
