Principal Engineer, Survivability (R4608)

What you'll do

• Design and optimize low observable (LO) features across the airframe focusing on shaping, edge treatments, radar-absorbing materials, and subsystem integration.
• Conduct modeling and simulation of electromagnetic signatures using industry-standard tools such as HFSS, CST Studio Suite, Xpatch, and SENTRi.
• Work with multidisciplinary teams in propulsion, avionics, structures, and AI to ensure survivability is baked into the system architecture from day one.
• Lead or support signature testing efforts, including indoor and outdoor RCS range tests, validation campaigns, and supplier-level hardware evaluations.
• Translate mission threats and requirements into survivability features that address RCS, thermal, visual, and acoustic observability constraints.
• Partner with materials scientists to mature radar-absorbing coatings and structural RAM for manufacturability and field durability.
• Support internal and customer assessments, threat modeling reviews, and milestone decisions throughout the program lifecycle.

Required qualifications

• B.S. or M.S. in Aerospace Engineering, Electrical Engineering, Physics, or a related discipline.
• 10+ years of hands-on experience in LO or survivability engineering, preferably on tactical aircraft, UAVs, or stealth systems.
• Proficiency with EM simulation tools such as HFSS, CST, Xpatch, or SENTRi.
• Strong understanding of RCS shaping principles, edge treatments, cavity suppression, and materials integration.
• Practical experience with LO testing methods and RCS measurement equipment.
• Familiarity with radar-absorbing materials (RAM), LO coatings, and structural LO trade studies.
• Solid collaboration and communication skills with the ability to work across design, test, and manufacturing teams.
• U.S. Citizenship and active Secret clearance required.

Preferred qualifications

• Experience with military UAV platforms or 5th-gen fighter programs.
• Background in survivability analysis in contested environments (e.g., IADS, radar networks).
• Familiarity with platform CONOPS, threat modeling, and mission-level survivability assessments.
• Ability to contribute to the design, test, and fielding of a fully integrated LO platform.
• Active Top Secret or SCI clearance.
