About The Position

KBR's National Security Solutions team is seeking a highly motivated and hands-on Semiconductor Device Engineer for an entry-level role (0-2 years of experience) focused on researching Ga-polar and N-polar Gallium Nitride devices. This position requires a strong foundation in semiconductor physics and a desire to work directly in a cleanroom environment. The engineer will bridge the gap between virtual modeling and physical realization by performing TCAD simulations, fabricating test structures in a state-of-the-art cleanroom, conducting DC/RF electrical testing, and inspecting devices using advanced microscopy. The role involves close collaboration with senior engineers to accelerate technology development and optimize device performance.

Requirements

Bachelor’s degree in Electrical Engineering, Materials Science, Physics, Nanoengineering, or a closely related engineering field.
0 to 2 years of hands-on cleanroom experience (can include undergraduate research, senior capstone design projects, or internships)
Familiarity with standard cleanroom protocols, safety standards, and basic microfabrication processing techniques.
Basic experience with semiconductor parametric testing equipment (e.g., source measure units, lock-in amplifiers).
Hands-on experience or coursework exposure to DC/RF electrical characterization concepts.
Direct experience operating optical microscopes; exposure to SEM or AFM is highly desirable.
Exposure to TCAD simulation software (e.g., Sentaurus, Silvaco, or COMSOL) through coursework or academic projects.
Strong written and verbal communication skills, with an eagerness to learn from senior mentors and collaborate in a fast-paced laboratory setting.
Must possess the ability to obtain and maintain a U.S. Government clearance. Public Trust clearance required.

Nice To Haves

Hands-on experience with Ga-polar and N-polar Gallium Nitride device modeling and fabrication.
Experience using scripting languages (such as Python or MATLAB) to automate data extraction, instrumentation control, or analyze large testing datasets.
Prior internship in a semiconductor lab or an academic cleanroom facility.
Familiarity with calibration techniques for RF testing.
Experience interpreting cross-sectional SEM images and surface topography profiles from AFM.

Responsibilities

Spend active time in the cleanroom environment assisting with process steps, managing test runs, and operating fabrication equipment (e.g., photolithography, wet/dry etching, thin-film deposition).
Utilize TCAD simulation tools (e.g., Synopsys Sentaurus, Silvaco) under the guidance of senior engineers to model basic device physics, predict electrical behaviors, and guide physical experiments.
Set up and execute parametric electrical testing. Perform DC measurements (I-V, C-V) and RF/high-frequency measurements (S-parameters) using manual or semi-automated probe stations, parameter analyzers, and network analyzers.
Conduct physical characterization and failure analysis on fabricated devices using advanced microscopy tools, including Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and optical microscopes.
Compile, analyze, and present experimental data. Compare electrical measurements against TCAD simulation results to identify discrepancies and suggest device improvements.
Maintain rigorous documentation of cleanroom runs, testing protocols, and safety procedures.
