Senior Rf Engineer Jobs in Ohio (NOW HIRING)

Title:
Semiconductor Device Engineer
Belong. Connect. Grow. with KBR!
KBR's National Security Solutions team provides high-end engineering and advanced technology solutions to our customers in the intelligence and national security communities. In this position, your work will have a profound impact on the country's most critical role - protecting our national security.
Why Join Us?

• Innovative Projects: KBR's work is at the forefront of engineering, logistics, operations, science, program management, mission IT and cybersecurity solutions.

• 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.
Key Responsibilities:
• 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.
Work Environment:

• Location: On-Site
• Travel Requirements: Minimal 0-20%
• Working Hours: Standard

Required Qualifications:
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.
Testing & Metrology:
• 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.
Desired Qualifications:
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.
