Job description

Team Overview

PsiQuantum's Applications Software Engineering Team (ASET) builds tools for quantum algorithm developers: cloud development environments, circuit design tools, and resource estimation systems. Our most recent public release is PsiQuantum's open access Construct platform that helps researchers write, simulate, and optimize quantum algorithms for the world's first utility-scale, fault‑tolerant quantum computer.

Role Overview

We're looking for someone to take ownership of ASET's infrastructure and pipelines from our existing platform engineer, continuing to grow our platform and making it easier for quantum researchers to do their best work.

That platform includes AWS infrastructure, Terraform configs, CI/CD workflows, and resources our researchers depend on for large‑scale, computationally intensive quantum simulations. There's a real opportunity to shape how all of it evolves.

The right person for this role is comfortable making judgment calls under uncertainty; they will have a lot of latitude, and accountability to match.

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

Required Qualifications

• 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

Preferred Qualifications

• 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

What We're Not Looking For

• Candidates focused on enterprise‑scale batch computing rather than cloud‑native platform engineering
• Platform engineers without exposure to GPU workloads or HPC concepts
• Candidates who prioritize architectural purity over iterative delivery

PsiQuantum provides equal employment opportunity for all applicants and employees. PsiQuantum does not unlawfully discriminate on the basis of race, color, religion, sex (including pregnancy, childbirth, or related medical conditions), gender identity, gender expression, national origin, ancestry, citizenship, age, physical or mental disability, military or veteran status, marital status, domestic partner status, sexual orientation, genetic information, or any other basis protected by applicable laws.

Compensation

The ranges below reflect the target ranges for a new hire base salary. One is for the Bay Area (within 50 miles of HQ, Palo Alto), the second one (if applicable) is for elsewhere in the US (beyond 50 miles of HQ, Palo Alto). If there is only one range, it is for the specific location of where the position will be located. Actual compensation may vary outside of these ranges and is dependent on various factors including but not limited to a candidate's qualifications including relevant education and training, competencies, experience, geographic location, and business needs. Base pay is only one part of the total compensation package. Full time roles are eligible for equity and benefits. Base pay is subject to change and may be modified in the future.

U.S. Base Pay Range: $150,000 — $170,000 USD. Bay Area Pay Range: $165,000 — $185,000 USD.
