Mechanical/Aerospace Engineer

Radiance Technologies•Huntsville, AL

About The Position

Radiance Technologies is seeking an experienced Mechanical/Aerospace Engineer to lead structural, thermal, and aerodynamic design, analysis, and qualification for advanced missile airframes, control surfaces, and internal mechanical packaging. As part of the Hardware & Avionics IPT, the engineer will work closely with the SME / Lead Developer to translate aerodynamic profiles and 6-DOF trajectory loads into flight-ready airframe structures, Thermal Protection Systems (TPS), and mechanical interfaces for Control Actuation Systems (CAS) and propulsion units. The role includes mechanical architecture and CAD modeling, structural and aerothermal analysis, mass-properties management, mechanical integration with actuation, propulsion, and avionics systems, material selection, and coordination of manufacturing. The engineer will also plan and lead environmental qualification tests, support field and flight testing, and participate in failure reviews. The position requires an active US DoD Secret security clearance.

Requirements

B.S. in Mechanical Engineering, Aerospace Engineering, or a related discipline with at least 5 years of experience, or an M.S. with at least 3 years of experience, in missile, rocket, or high-performance aerospace structures.
Advanced proficiency in 3D CAD modeling using Siemens NX, CATIA V5/3DEXPERIENCE, or SolidWorks.
Strong hands-on expertise with FEA software such as ANSYS, NASTRAN, Abaqus, or FEMAP for structural, thermal, and dynamic stress analysis.
Deep understanding of high-speed aerodynamics, thermal protection systems, aero-heating load prediction, and structural dynamics, including vibration and shock.
In-depth knowledge of aerospace materials, including titanium, carbon composites, high-temperature alloys, and ablatives, and of precision manufacturing processes.
Must hold an active US DoD Secret security clearance.

Responsibilities

Lead mechanical architecture and CAD modeling of missile airframes, seekers, body tubes, fins/canards, and internal mounting structures.
Perform structural, modal, and aerothermal finite element analysis to verify structural integrity, thermal margins, and dynamic response under flight loads.
Manage mass properties, including center of gravity, moments of inertia, and total mass budgets, and coordinate with the GNC team to maintain aerodynamic stability profiles.
Integrate Control Actuation Systems, including fin shafts, high-torque gearboxes, linkage assemblies, and actuator housings, while ensuring minimal mechanical backlash and compliance under aerodynamic loads.
Design ruggedized mechanical enclosures, mounting chassis, and vibration-isolation assemblies for avionics, IMUs, power electronics, and thermal batteries.
Manage mechanical interfaces with solid rocket motors, including thrust vector alignment, thermal isolation, and structural load paths.
Select aerospace materials and apply Design for Manufacturability and Assembly principles in coordination with machine shops, composite fabricators, and additive manufacturing vendors.
Author test plans and lead environmental qualification testing for structural airframes and mechanical sub-assemblies.
Deploy to remote proving grounds and flight test ranges to support hardware assembly, launcher mechanical integration, pre-flight checks, and post-flight recovery and inspection.
Participate in Failure Review Boards chaired by the Chief Engineer and perform root-cause analysis of structural or mechanical anomalies.
