• Experience working with radiation detection systems (semiconductor detectors, scintillators, etc.)
• Experience working in analog and digital signal processing, including op amp circuit design and pulse analysis techniques (pulse height analysis, noise analysis, discriminator/comparator design, pulse shape discrimination, etc.).
• Experience with scientific programming and data analysis, especially Python and/or ROOT
• Ability to troubleshoot detector, electronics, software, and test-system issues.
• Excellent interpersonal, customer service, and communication skills (Oral and Written)
• Experience working in an electronics lab setting. Including familiarity with ESD safe practices, familiarity with lab equipment (oscilloscopes, DC power supplies, etc.).

Preferred Skills and Qualifications:

• Ph.D. in electrical, nuclear, or electrical engineering, radiation detection, medical or space physics or related field
• amiliarity with Timepix, Medipix or other hybrid pixel detector systems
• Experience with NASA/JSC hardware development, processing, testing, or flight hardware practices
• Experience handling radioactive sources
• Experience with accelerator or beamline testing
• Experience with radiation transport or detector response modeling
• Knowledge of NASA Standard 3001 as applicable radiation requirements
• Demonstrated ability to grow into technical ownership or project leadership
