The Space Sciences Laboratory (SSL) at the University of California, Berkeley seeks applications for a full-time 100 % Assistant or Associate Researcher with an expected start date between June 2020 and September 2020. The Assistant or Associate Researcher will work on on the LiteBIRD mission cosmic microwave background (CMB) space mission. Level at the Assistant or Associate Researcher rank will be determined upon review of application materials.

About The Space Sciences Laboratory (SSL) at the University of California, Berkeley:
Built six decades ago, UC Berkeley’s Space Sciences Laboratory (SSL) was the realization of NASA’s vision to gather many of the most innovative and dedicated science minds in one place at Berkeley. In the hill above Berkeley, physicists, researchers, biologists, engineers and technicians worked in unison: interacting, learning from one another, leading, challenging and inspiring one another in creating cutting-edge space science instrumentation and conducting top research. Through sixty years of NASA-funded support, their efforts, and those of hundreds of dedicated students and staff, have brought about myriad highlights, such as the space science missions of S3-3, ISEE, Polar, Van Allen Probes, Cluster, IMAGE, THEMIS and MAVEN. All have contributed to new discoveries about the physics of space, and initiated marked new advances in engineering technology.

LiteBIRD is a space mission to search for the signature of primordial gravitational waves from the epoch of the Big Bang. The spacecraft will observe from the second Lagrangian point with a bolometer focal plane operated at 100mK. The main mission was accepted by JAXA in March 2019, and a proposal has been submitted to NASA for a “mission of opportunity” to build the three bolometric focal planes of the LiteBIRD baseline design. A proposal process is also active in Europe to build two of the three telescopes and the 100 mK cooler.

The Assistant or Associate Researcher will lead the integration and test of the LiteBIRD focal-plane arrays. LiteBIRD will use lenslet- and horn-coupled transition-edge sensor focal planes. The Assistant or Associate Researcher will participate in the design of the detectors, readout, and focal-plane arrays and interface with partners in Japan and Europe. The Assistant or Associate Researcher may supervise postdoctoral fellow(s) and graduate student(s).

Assistant or Associate Researcher will:

  • Lead the integration and test of the LiteBIRD focal-plane arrays
  • Will participate in the design of the detectors, readout, and focal-plan array and interface with partners in Japan and Europe
  • May supervise postdoctoral fellow(s) and graduate student(s)

Basic Qualifications:
PhD or equivalent international degree required at the time of application.

Additional qualifications (required at start date of position):

  • Minimum of 4 years of post PhD experience
  • Experience with sub-Kelvin temperature cryogenics, TES bolometer arrays, and SQUID multiplexer readout electronics.
  • Record of Publications since PhD degree

Preferred qualifications

  • PhD in Physics, Astronomy, or a closely related field
  • Prior experience applying for grants or contracts to support new projects
  • Experience with Integration and Test of cosmic microwave background (CMB) experiments.
  • Experience supervising PhD students
  • Familiarity with space-based astrophysics missions

Salary and Benefits:
Starting salary will be commensurate with experience.

Initial appointment will be for two years, with the possibility of renewal based on performance and availability of funding.

The university provides a comprehensive benefits program which offers Medical, Dental, Vision, Life and AD&D Insurance, Short-Term Disability Insurance and Long-Term Disability Insurance. For a complete guide on UC Health Benefits for staff, please visit:
