    In this position, you will be responsible for key aspects of the company's radiation hardness assurance program. CesiumAstro's products address market segments that include high-volume LEO applications as well as higher orbits; as such, the successful candidate will have extensive industry experience using modern, cutting-edge devices in space applications. Technical work will include environment analysis, testing, risk management, and product road-mapping. More detailed responsibilities are listed below.
    The successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.

    • Own key aspects of the company's Radiation Hardness Assurance Plan for LEO orbits and beyond.
    • Simulate radiation environments for various orbits using tools such as OMERE.
    • Plan and conduct radiation tests on components and CesiumAstro's products, including proton, heavy ion, and total dose testing.
    • Predict upset rates by combining environmental simulations with test data.
    • Advise hardware engineers on part selection.
    • Advise software and firmware engineers on best practices for "software radiation tolerance" such as EDAC and watchdog timer.
    • Perform system-level analysis of radiation risk.
    • Participate in design reviews for hardware, software, and firmware to ensure radiation reliability.
    • Digest requirements from potential customers to shape our product-level radiation roadmap.
    • Keep up with the latest industry practices, standards, and requirements.
    • Help to grow the radiation effects team via interviews, training, and mentorship.
    • Advise Business Development on radiation effects for bids and proposals.

    JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
    • Bachelor of Science (BS) or higher degree in Electrical Engineering, Physics, or similar degree from an accredited university.
    • Minimum of 4 years of space product experience.
    • Direct experience performing many or all of the responsibilities listed above.
    • Direct experience working with automotive and high volume commercial grade parts in radiation environments.
    • Good understanding of the radiation physics relevant to electronic components.
    • Excellent written and spoken communication ability.

    PREFERRED EXPERIENCE
    • Experience with ray tracing tools such as FASTRAD
    • Experience with radiation susceptibility of RF components including III-V transistors (GaAs, Gan)
    • Specialization of SEE analysis and test of complex digital devices such as FPGAs, processors, and memories (RAM and NVM)
    • Working knowledge of Electronic Circuit Theory.
    • Basic programming and scripting, such as Python.
    • Managing databases of component test data.
