Design and implement the architecture managing the DAG controller and the orchestration layer for initial and periodic recalibrations.
Define node semantics: inputs, outputs, idempotence, delays, retries, and safe rollback behavior.
Implement a policy engine for top-down controls and conditional decision trees that trigger recalibrations.
Develop operator workflows for pause, diagnostics, suggested fixes, and resuming from failed nodes.
Collaborate with experimentalists to translate calibration procedures into robust orchestration primitives.
Ensure reliability through automated testing (unit, integration, hardware-in-the-loop) and runbook automation.

At least 5 years of experience in software engineering, ideally on production orchestration or workflow systems.
Strong Python skills; experience developing reliable control software for hardware.
Experience with workflow/DAG frameworks (e.g., Airflow, Prefect, or custom orchestration).
Proven track record with fault-tolerant systems, including retries, idempotence, and observability.
Knowledge of instrument and hardware control interfaces (SCPI, VISA, gRPC, serial) or willingness to learn.
Experience with hardware-in-the-loop testing strategies and CI/CD pipelines.
Excellent communication skills and ability to collaborate with experimental scientists.
