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.

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, CREME
96, 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

Qualifications:

Required:

U.S. Citizenship required with the ability to obtain and maintain a security clearance

Bachelor's degree in Aerospace, Electrical, Physics, or related Engineering field3-5 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, CREME
96, 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

Desired:

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-What You Can Expect: A culture of integrity.
