Mechanical Engineer

About this role

Aurelius Systems seeks a Mechanical Engineer to design ruggedized fiber laser weapon systems that survive extreme shock, vibration, moisture, and field conditions. You'll drive survivability architecture from concept through field validation, working hands-on across structural design, FEA, and test correlation for deployable directed energy systems.

What you'll do

• Design structural and mechanical systems for MIL-STD compliance across shock, vibration, humidity, dust, and austere environments
• Develop ruggedization strategies for laser sources, heads, and subsystems including sealing, ingress protection, and corrosion mitigation
• Perform FEA modeling including static, modal, random vibration, and shock response spectrum analysis
• Design and validate vibration isolation systems with modal analysis and snubbing optimization
• Build and instrument structural test rigs, correlate physical results to models, and perform shock/drop survivability assessments
• Execute design trades balancing ruggedization performance against mass, stiffness, and packaging constraints

What they're looking for

• FEA software (ANSYS, Nastran, Abaqus, or equivalent)
• MIL-STD-810 shock and vibration design standards
• Structural test rig design and instrumentation
• Sealing, EMI/EMC gasket, and conformal coating design
• Enclosure and field-deployable structure design
• Vibration isolation and modal analysis
• Shock response and fragility analysis
• Model-to-bench correlation and validation
