About The Position

We are seeking a Space Radiation & Survivability Engineer to join our engineering team. In this role, you will support the analysis, design, and verification of spacecraft systems to ensure survivability in the harsh radiation and space environments encountered throughout mission life. This is a mid-level technical position for an engineer with foundational experience who is ready to take on increased ownership of radiation effects analysis and hardware survivability tasks.

Requirements

U.S. Citizenship required with the ability to obtain and maintain a security clearance
Bachelor's degree in Aerospace, Electrical, Physics, or related Engineering field
3-5 years of relevant experience in space radiation effects, survivability engineering, or related space systems engineering
Working knowledge of space radiation environments and effects on electronics (TID, DDD, SEE)
Familiarity with radiation analysis and transport tools (e.g., FASTRAD, CREME96, or equivalent)
Understanding of EEE parts radiation hardness assurance principles
Strong written and verbal communication skills; ability to produce clear technical documentation
Ability to work both independently and collaboratively in a cross-functional engineering environment

Nice To Haves

Master's degree in a relevant engineering or physics discipline
Experience supporting radiation test campaigns at accelerator facilities (proton, heavy ion)
Familiarity with MIL-STD-883, MIL-STD-750, or NASA radiation testing/analysis standards
Experience with spacecraft charging analysis (NASCAP, SEE Interactive, or similar)
Experience supporting proposal development and technical cost estimation

Responsibilities

Perform radiation environment definition (trapped protons/electrons, galactic cosmic rays, solar particle events) for various orbits and mission profiles
Conduct total ionizing dose (TID), displacement damage dose (DDD), and single event effects (SEE) analyses for electronic components and subsystems
Support shielding analysis and mass trade studies to meet radiation tolerance requirements
Work with parts engineering to assess radiation hardness assurance (RHA) of EEE parts and recommend mitigation strategies
Support survivability analysis against other space environment threats, including charging/discharging, micrometeoroid/orbital debris (MMOD), thermal extremes, and EMP/nuclear environments as applicable
Develop and maintain radiation analysis tools, models, and simulations (e.g., FASTRAD, CREME96, or equivalent)
Collaborate with systems engineers, hardware designers, and part engineers to translate radiation requirements into design guidelines
Participate in design reviews (PDR, CDR) and generate supporting analysis documentation
Support test planning and execution for radiation qualification testing (TID, SEE, proton/heavy-ion testing at accelerator facilities)
Document analysis methodologies, assumptions, and results in formal reports and technical memoranda
Interface with customers and government agencies on radiation and survivability requirements as needed
