Software Infrastructure & Platform Engineer

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. 

In 2024, PsiQuantum announced 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 defining—and that now is the time to scale. 

PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact. 

Quantum computing is not an extension of classical computing. It represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real. 

Come join us. 

Team Overview

PsiQuantum’s Quantum Applications Software Team is dedicated to creating a software environment where quantum application developers can discover, build, utilize, optimize, and visualize large-scale quantum algorithms for classically intractable problems. As we continue to scale, we’re building out a DevOps function that bridges classical software DevOps best practices with cutting-edge quantum software development.

Role Overview

We seek a Platform Engineer with deep expertise in AWS infrastructure, Infrastructure as Code (IaC), and CI/CD automation to architect and maintain scalable, secure systems. This hands-on role bridges engineering and operations—you’ll build foundational IaC frameworks, enforce security rigor, and collaborate with QA/development teams to ensure reliability, observability, and rapid iteration.

You’ll have the opportunity to:

• Build and own critical infrastructure using Terraform, AWS CDK, and Pulumi, balancing developer agility with enterprise-grade security.
• Champion DevOps practices by automating workflows, hardening CI/CD pipelines, and implementing proactive monitoring.
• Partner with cross-functional teams (QA, product, engineering) to align infrastructure with compliance, scalability, and uptime goals.

Responsibilities:

• Design and Maintain IaC Foundations: Write modular, reusable Terraform/Pulumi code to provision AWS services (EKS, RDS, VPC, etc.), ensuring multi-account networking and cross-environment parity.
• Automate CI/CD Pipelines: Oversee GitLab CI workflows (builds, tests, deployments) and integrate security checks (IAM, KMS) into every stage.
• Collaborate on System Reliability: Partner with QA teams to design testable infrastructure, debug deployment failures, and validate pre/post-deployment system health.
• Implement Observability: Deploy monitoring/logging tools (e.g., CloudWatch, Prometheus, Grafana) to preempt issues, optimize performance, and ensure SLA compliance.
• Enforce Security Best Practices: Embed authentication/authorization controls (Okta, IAM) and compliance standards (e.g., public sector requirements) into infrastructure design.
• Document and Iterate: Create runbooks for incident response, disaster recovery, and infrastructure scaling to minimize downtime.

Required Qualifications:

• Bachelor’s Degree in Computer Science, Engineering, or a related field.
• 5+ years in DevOps/Platform Engineering with hands-on AWS expertise (EKS, IAM, VPC, S3) and multi-account networking (transit gateways, peering, security groups).
• Proven IaC Experience: Designed and deployed production infrastructure using Terraform and Pulumi/AWS CDK.
• CI/CD Ownership: Built and maintained GitLab CI/GitHub Actions pipelines with artifact management, rollback strategies, and parallelized jobs.
• Containerization & Microservices: Shipped Dockerized apps on ECS/EKS and serverless workloads (Lambda, API Gateway) with zero-downtime deployments.
• Agile/Scrum Fluency: Collaborated in sprint-based teams to prioritize infrastructure work alongside feature development.
• Multi-Environment Governance: Managed dev/staging/prod parity using IaC, feature flags, and environment-specific configurations.

Preferred Qualifications:

• Database Optimization: Tuned RDS/DynamoDB/Redis clusters for scalability and low-latency access.
• Security & Compliance: Implemented Auth0/Okta, KMS encryption, or FedRAMP/IRAP-aligned systems for public sector clients.
• HPC/Advanced Compute: Deployed domain-specific containerization (Apptainer/Singularity) or managed GPU/ML clusters.
• AWS Certifications: Solutions Architect, DevOps Engineer, or Security Specialty certifications.
• Scripting Proficiency: Python/Bash for automation, tooling, or glue code.
• Quantum Curiosity: Exposure to quantum SDKs (Qiskit/Cirq) or hybrid classical-quantum workflows.
