Radiation Metrology and Test Engineer

The role

You will build hardware, automation, and measurement systems to understand how electronics behave under radiation. You will own reusable radiation test infrastructure including circuit design, bench checkout, test execution, and data processing.

What you will do

• Develop reusable test electronics including motherboards, daughterboards, bias and protection circuits, fixtures, and interfaces.
• Build reliable test automation software for instrument control, stimulus generation, electrical characterization, event logging, and data reduction.
• Establish calibration and verification procedures for the electrical measurement chain.
• Prepare and execute radiation campaigns including heavy-ion and other component radiation tests.
• Coordinate sample preparation, beam access, and facility interfaces.
• Make exposure and response data traceable by recording exposure conditions and device operating states.
• Turn test runs into engineering evidence through device characterization and reproducible analysis.
• Sustain the broader test capability by improving characterization benches, tools, and procedures.

Required qualifications

• A degree in electrical engineering, computer engineering, physics, or a related discipline, or equivalent practical experience.
• Hands-on experience testing electronic hardware under radiation, with an understanding of single-event effects and total ionizing dose.
• Experience designing, bringing up, and debugging PCB-based test hardware, including bias circuits, component interfaces, and electrical measurements.
• Ability to develop maintainable test automation and data-analysis software in Python or a comparable language.
• Practical experience with instruments such as source measure units, oscilloscopes, power supplies, and data-acquisition systems.
• Careful measurement and documentation habits.

Nice to have

• Heavy-ion or proton testing at external facilities, including device preparation and beamline setup.
• High-voltage or power-semiconductor characterization, including protection and recovery during testing.
• Embedded C/C++, microcontroller or FPGA interfaces, and instrument-control libraries.
• Radiation test methods and standards, uncertainty analysis, or development of reusable test platforms.

Benefits

• Equity in Cowboy Space Corp.
• Medical, dental, and vision insurance for employees and eligible dependents
• 401(k) retirement savings plan
• Paid time off
• 10 paid holidays per calendar year
• Paid parental leave
• Relocation assistance if applicable
• Daily lunch in the office
• Fully stocked kitchen with beverages and snacks

Before you apply

• Applicants must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Depar
