Aurelius Systems
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

- Walk us through a system you designed that had to survive MIL-STD-810 shock and vibration in a deployable package. What were the critical failure modes and how did you validate your design?
- Describe your experience with FEA for vibration and shock analysis. Which tools have you used, and can you give an example where your model predictions correlated well—or poorly—with physical testing?
