Software Infrastructure & Platform Engineer

Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world-changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.

By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.

PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier-1 semiconductor fabs such as GlobalFoundries where we leverage high-volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.

In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry-transforming results.

Quantum computing is not just an evolution of the decades-old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.

There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!

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 QA function that bridges classical software QA 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.
