Senior Software Platform Engineer

PsiQuantum is focused on building the first useful quantum computers. They are seeking a Senior Software Platform Engineer to take ownership of their Applications Software Engineering Team's infrastructure and pipelines, optimizing AWS infrastructure and deployment processes for quantum algorithm developers.

Responsibilities:

• Own our AWS infrastructure end-to-end and actively shape how it evolves; building and optimizing, not just maintaining
• Reduce friction in the deployment pipeline so developers can ship features with confidence
• 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
• Develop relationships and work closely with platform engineers across PsiQuantum, including to leverage HPC/GPU resources
• Make deployments faster to roll out, easier to roll back, and less prone to failure
• Lead incident response and post-mortems when necessary

Requirements:

• 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: You've 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
• Background in scientific computing, research infrastructure, ML platforms, or early-stage startups (especially research computing vendors)
• GPU/HPC experience: Supported GPU workloads in production environments, including code optimization, CUDA debugging, and job scheduler setup
• Security & compliance experience: You've implemented auth systems (Auth0/Okta), managed encryption (KMS), or worked on compliance-driven infrastructure
• 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
