Description
Job Details New ideas are all around us, but only a few will change the world. That’s our focus at JPL. We ask the biggest questions, then search the universe for answers—literally. We build upon ideas that have guided generations, then share our discoveries to inspire generations to come. Your mission—your opportunity—is to seek out the answers that bring us one step closer. If you’re driven to discover, create, and inspire something that lasts a lifetime and beyond, you’re ready for JPL. Located in Pasadena, California, JPL has a campus-like environment situated on 177 acres in the foothills of the San Gabriel Mountains and offers a work environment unlike any other: we inspire passion, foster innovation, build collaboration, and reward excellence. JPL is unique among NASA Centers  in  that its staff a re  Caltech employees, yet can access NASA technical  re sources. Cross-discipl in e teamwork is st and ard he re : colleagues across JPL's science  and  eng in eer in g organizations  and  on Caltech's academic campus often work together. Learn in g to speak  and  underst and  other discipl in es' languages is a doorway to the c re ativity needed to do what has not been done be for e. JPL staff a re  encouraged to c re ate mission concepts that add re ss humanity's co re  questions through a comb in ation of science  and  technology. They a re  supported  in  develop in g ideas  in to proposals  and  hardwa re ,  and   in  communicat in g funded missions'  re sults to the scientific community  and  the broader public. JPL seeks to employ scientists  and  eng in eers who a re  passionate about lifelong learn in g  and  excited to both contribute to  and  lead team ef for ts. We emphasize the importance of partner in g across discipl in e boundaries  and  c re at in g a friendly, constructive work environment to overcome space exploration's challenges. The  Postdoc toral scholars at JPL benefit from an  in for mal mentor in g network, an annual confe re nce showcas in g their  re sults, a dedicated sem in ar series, exposu re  to diverse ca re er paths,  and  social connections across the JPL  and  Caltech community  for  advice on hous in g, childca re ,  and  other aspects of liv in g  in  southern Cali for nia. JPL is look in g  for  a  postdoc  who will jo in  the Quantum Science & Technology  re search community  and  contribute to ongo in g ef for ts  in  p re cision tim in g  and  quantum technologies. This work supports the cont in ued advancement of ion clock  re search capabilities at JPL  and  contributes to futu re  applications  in  space-based tim in g systems  and  quantum-enabled technologies. This position  in volves experimental  re search  in  the design, development, operation,  and  test in g of trapped ion systems  for  p re cision f re quency st and ards  and  quantum tim in g applications. The  re search emphasizes h and s-on laboratory work  in volv in g ion trapp in g systems, cold atom systems, p re cision measu re ments, numerical simulations, laser systems, vacuum systems,  and quantum measu re ment techniques  re levant to state-of-the-art atomic clock  and  quantum technologies. The  postdoc  will contribute to the advancement of next-generation ion clock architectu re s through experimental  in vestigation, system  re f in ement,  and  per for mance characterization.
