CesiumAstro develops advanced communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We are seeking a Senior Radiation Effects Engineer II to lead key aspects of our radiation hardness assurance program.
In this role, you will own the company's Radiation Hardness Assurance Plan for LEO orbits and beyond, working across hardware, software, and firmware teams to ensure radiation reliability. You will simulate radiation environments for various orbits using tools such as OMERE, plan and conduct radiation tests on components and products (proton, heavy ion, and total dose testing), and predict upset rates by combining environmental simulations with test data.
Key responsibilities include:
- Owning the Radiation Hardness Assurance Plan for LEO and higher orbits
- Simulating radiation environments using modern tools
- Planning and conducting radiation testing on components and products
- Predicting upset rates and performing system-level radiation risk analysis
- Advising hardware engineers on part selection and software/firmware engineers on radiation tolerance best practices (EDAC, watchdog timers)
- Participating in design reviews for hardware, software, and firmware
- Digesting customer requirements to shape product-level radiation roadmap
- Staying current with industry practices, standards, and requirements
- Mentoring and growing the radiation effects team
- Supporting Business Development on radiation effects for bids and proposals
- Presenting engineering design review materials to customers and executive leadership
You will work in a dynamic, cross-functional startup environment with hands-on, autonomous work. Excellent written and verbal communication skills are essential, as you will present to customers and leadership regularly.
REQUIREMENTS:
- Bachelor of Science or higher degree in Electrical Engineering, Physics, or similar discipline from an accredited university
- Minimum 5 years of space product experience
- Direct experience performing the responsibilities listed above
- Direct experience working with automotive and high-volume commercial-grade parts in radiation environments
- Strong understanding of 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 in SEE (Single Event Effect) analysis and testing of complex digital devices such as FPGAs, processors, and memories (RAM and NVM)
- Working knowledge of Electronic Circuit Theory
- Basic programming and scripting (e.g., Python)
- Managing databases of component test data
NOTE: Applicant must be a U.S. citizen, lawful permanent resident, conditional resident, asylee, or refugee, or eligible to obtain required authorizations from the U.S. Department of State to comply with U.S. Government Space Technology Export Regulations.
