Job summary

Aurelius Systems in San Francisco is seeking a Mechanical Engineer to lead ruggedization of a fiber laser system for field deployment. You’ll design for survivability against shock, vibration, moisture, and extreme environments, from architecture through bench validation.

You’ll perform FEA with ANSYS/Nastran/Abaqus, specify MIL-STD-810 compliant hardware, instrument test rigs, and validate models against real-world tests in a startup setting.

Qualifications

• 3 to 10+ years in mechanical engineering on ruggedized or field-deployable systems.
• Strong FEA experience with ANSYS, Nastran, Abaqus, or equivalent.
• Hands on experience designing to MIL-STD-810 or equivalent shock and vibration standards.
• Track record building and instrumenting structural test rigs and correlating model to bench.
• Experience with sealing, EMI/EMC gaskets, conformal coating, and environmental protection design.
• Experience designing enclosures and structures for field-deployable or military conditions.

Responsibilities

• Structural and mechanical design for survivability across MIL-STD shock, vibration, humidity, dust, and austere environments.
• Ruggedization architecture across the laser source, laser head, and supporting subsystems.
• Sealing, ingress protection, and moisture/corrosion mitigation strategies (IP ratings, conformal coatings, gasket design).
• Vibration isolation system design including isolator selection, snubbing, and modal analysis.
• Shock analysis and design including fragility assessment, cushion design, and drop/transportation survivability.
• FEA modeling including static, modal, random vibration, and shock response spectrum analysis.
• Structural validation including instrumentation, test rigs, and correlation to model.
• Trades between ruggedization performance, mass, stiffness, and packaging across the system.
