PsiQuantum is looking to build the first useful quantum computers—machines capable of delivering the breakthroughs the field has long promised, by solving problems that even the most advanced supercomputers or AI systems will never reach, with impact spanning energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Requirements
- 8+ years building backend/platform systems in Python, including leading significant re-architecture efforts.
- Expert-level Python (async, packaging, profiling) with production experience in FastAPI/Flask/Django and typed interface patterns (pydantic/mypy).
- Demonstrated success shipping reproducible pipelines or workflow engines that span HPC/Slurm-style schedulers and cloud infrastructure, including task orchestration and artifact provenance.
- Deep AWS + Terraform experience across multi-environment deployments; comfortable wiring auth layers and managing secrets/service identities.
- Strong database and state-system background (Postgres/MySQL/Mongo + Redis/Valkey), covering schema design, migrations, query tuning, and cache/state orchestration.
- History of designing and maintaining internal APIs/SDKs (REST/gRPC/Python clients) with clear contracts, versioning, and documentation practices.
Responsibilities
- Lead the redesign of our core architecture platform backend, defining clear service boundaries and APIs in Python so simulation, data, and UI layers stay decoupled and manageable.
- Build resilient Python-first pipelines that move jobs, configs, and artifacts between on-prem/HPC environments and cloud services, emphasizing reproducibility and debuggability.
- Own database and caching strategy-schema/version design, indexing, migrations, and Redis/Valkey-backed state layers-so long-lived experiments evolve without breaking downstream users.
- Stand up and operate Terraform-managed AWS infrastructure (EC2/EKS/S3/IAM, etc.), integrate authN/Z (OAuth2/OIDC/SSO), and embed logging/metrics/tracing for operational clarity.
- Deliver internal tooling (CLIs, REST/gRPC endpoints, Python SDKs) and documentation that let researchers and engineers launch, observe, and compare simulations without digging through multiple repos.
- Raise the engineering bar: typed Python, thorough testing, CI/CD gates, and mentoring peers on platform design, performance tuning, and modular system composition.
Other
- 8+ years of experience
- Equal employment opportunity for all applicants and employees
