Mechanical Simulation Engineer

FIRST RF is seeking a highly motivated Mechanical Engineer with demonstrated expertise in FEA analysis methods to support the development of advanced RF and antenna systems for defense and aerospace applications.

This role focuses on structural, shock, dynamic, and thermal simulation of complex electronic and RF assemblies operating in demanding environments across land, sea, air, and space platforms.

You will work closely with multidisciplinary engineering teams to predict and solve mechanical challenges before hardware is built, helping ensure mission-critical performance and reliability for our customers.
