Collaborative Environment:
Be part of a dynamic team that thrives on collaboration and innovation, fostering a supportive and intellectually stimulating workplace.

Impactful Work:
Your contributions will be pivotal in designing and optimizing defense systems that ensure national security and shape the future of space defense.

We are seeking a highly motivated and hands-on Semiconductor Device Engineer to join our team researching Ga-polar and N-polar Gallium Nitride devices. This entry-level role (0-2 years of experience) is designed for an engineer with a strong foundation in semiconductor physics and a desire to work directly in a cleanroom environment. In this role, you will bridge the gap between virtual modeling and physical realization by performing TCAD simulations, fabricating test structures in our state-of-the-art cleanroom, conducting DC/RF electrical testing, and inspecting devices using advanced microscopy.

You will work closely with senior engineers to accelerate technology development and optimize device performance.

• Cleanroom Fabrication & Process Support:
  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).
• Device Simulation (TCAD):
  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.
• Electrical Characterization (DC & RF):
  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.
• Microscopy & Metrology:
  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.
• Data Analysis & Reporting:
  Compile, analyze, and present experimental data. Compare electrical measurements against TCAD simulation results to identify discrepancies and suggest device improvements.
• Documentation & Safety compliance:
  Maintain rigorous documentation of cleanroom runs, testing protocols, and safety procedures.

Education:

Bachelor’s degree in Electrical Engineering, Materials Science, Physics, Nanoengineering, or a closely related engineering field.

Experience:

0 to 2 years of hands-on cleanroom experience (can include undergraduate research, senior capstone design projects, or internships)

Fabrication

Skills:

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.
• Simulation & Software:
  Exposure to TCAD simulation software (e.g., Sentaurus, Silvaco, or COMSOL) through coursework or academic projects.

Communication & Teamwork:
Strong written and verbal communication skills, with an eagerness to learn from senior mentors and collaborate in a fast-paced laboratory setting.

Security Clearance:
Must possess the ability to obtain and maintain a U.S. Government clearance. Public Trust clearance required.
