About the role

  • Architect the **services, APIs, and internal frameworks** powering experiment workflows, calibration systems, automation loops, and configuration management.
  • Choose and integrate appropriate storage technologies (SQL, NoSQL, object stores, columnar formats) to support scaling needs and diverse access patterns.
  • Define architectural patterns that maximize **agility, modularity, and maintainability** across the platform.
  • Collaborate closely with physicists and researchers to ensure models and interfaces reflect real experimental needs and enable fast iteration.
  • Partner with data engineering to build reliable ingestion paths, schema governance, data lifecycle strategies, and cross-team storage standards.
  • Shape the end-to-end architecture required to deliver the QPU as a **cohesive product**: API design, user orchestration, deployment strategy, and integration with HPC/cloud ecosystems.
  • Drive long-term architectural strategy, technical roadmap, and cross-organizational alignment.
