Summary: Deep Space Atomic Clock and cold-atom-in-space (CAL/BECCAL heritage) programs make JPL a top destination for space-based quantum-sensing postdocs; managed jointly with Caltech.

Notes: Extremely tight collaboration with Caltech; unmatched flight-hardware experience for sensing instruments.

Warnings: US-citizenship or permanent-residency requirements apply to many JPL positions due to ITAR/export-control restrictions, significantly limiting eligibility for international postdocs.
