  • Experience with typical ultrasonic test equipment, including transducers, immersion scanning systems, and phased arrays.
  • Experience developing algorithms and applying data-processing techniques for wave propagation.

About the Company

Lawrence Livermore National Laboratory (LLNL)

National security research laboratory

LLNL conducts scientific and technological research funded by the U.S. government to address national security, energy, and environmental challenges. Its multidisciplinary teams create technologies through projects funded by contracts and grants, delivering outputs such as advanced materials, simulations, software, and vaccines. Unlike private vendors, LLNL operates as a national laboratory with access to unique facilities and mission-driven funding, collaborating with government, universities, and industry. Its goal is to apply science and engineering to protect people, improve energy and environmental sustainability, and advance national security and public welfare.
