Mechanical Simulation Engineer

Summary

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.

Key Responsibilities

• Lead structural, thermal, and dynamic simulations for RF systems and electronic assemblies using a suite of Altair (now Siemens) simulation tools (Hypermesh, Optistruct, RADIOSS, Hyperlife), and SolidWorks Simulation.
• Perform finite element analysis (FEA) to evaluate:
  • Thermal performance and heat dissipation
  • Thermo-Structural integrity
  • Shock and vibration survivability
  • Fatigue/Durability
  • Environmental requirements under MIL-STD-810 and related conditions
  • Develop and validate simulation models through correlation with environment, thermal, and vibration test data
• Collaborate with RF, mechanical, and electrical, and systems engineers to optimize designs for
• • Weight
  • Manufacturability
  • Reliability
  • Environmental performance
  • RF compatibility
• Support the design and packaging of high-reliability electronic and RF hardware for aerospace and defense applications
• Participate in technical and customer design reviews, presenting analysis results, and engineering recommendations
• Create and maintain engineering documentation, analysis reports, and test correlation data
• Support root-cause investigations and troubleshooting activities during integration and test
• Ensure compliance with ITAR, customer requirements, and applicable industry and military standards
