Thermal Engineer III

**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. **Responsibilities:** **The Instruments Division** provides engineering and technology leadership in the development of scientific instruments to explore the Earth, planets, and the cosmos. Applications include ground based, airborne, and space-based instruments and systems. Division capabilities range from instrument conceptual design through implementation, deployment, and calibration. The **Instruments Systems Section** provides the Laboratory with centers of expertise in system formulation and implementation of scientific and national instruments, including in-situ, ground, space based, airborne/suborbital and cryogenic instruments. Our section provides support from concept through delivery of instruments for program offices that include Earth Science, Planetary Science, and Astronomy. We partner with academic institutions and science communities. Instruments supported in our section include, but are not limited to: spectrometers, radiometers, magnetometers, microwave radiometers, Ultraviolet (UV)/Visible (VIS)/Infrared (IR)/Far-IR imagers.
