Company mission
To build and deploy useful, fault tolerant quantum computers.
Role
Who you are
- 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
Desirable
- 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
What the job involves
- 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
- 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
- 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
Our take
Quantum computing will change the world more than any other imminent technological development, and PsiQuantum sits at the forefront of the charge to build the first quantum computer that will actually work.
The company is unique for the scale of their ambitions. Rather than focusing on what they term “intermediate milestones” like building smaller proof of concept systems, PsiQuantum builds the first large-scale, error-corrected computer, using photonics to deliver over 1,000,000 qubits (current quantum machines have yet to cross the 1,000 qubit mark).
There are plenty of companies building quantum computers, including the likes of IBM and Google, but these prototypical machines lack the size to correct errors, making them exponentially less useful than what PsiQuantum aims for. While other companies operate in the same sphere, PsiQuantum is unequivocally a leader in its field, founded by world-class academics and recently securing $1B in funding, making it the largest funding round for a quantum computing startup.
