Software Infrastructure and Platform Engineer

Summary

Join PsiQuantum's Quantum Applications Software Team as a Platform Engineer and build the future of quantum computing. You will architect and maintain scalable, secure systems using AWS infrastructure, IaC, and CI/CD automation. This hands-on role requires expertise in Terraform, AWS CDK, and Pulumi, along with a strong understanding of DevOps practices. You will collaborate with cross-functional teams to ensure reliability, observability, and rapid iteration. The ideal candidate possesses a Bachelor's degree in a related field and 5+ years of relevant experience. PsiQuantum offers a competitive salary and benefits package.

Requirements

• 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

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

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
