Aurelius Systems Senior Mechanical Engineer owns major mechanical subsystems for ruggedized fiber laser systems. Designs for survivability, thermal management, and precision packaging from prototype to production.

Responsibilities

We need a Senior Mechanical Engineer who owns major mechanical subsystems on Archimedes end to end and makes them survive the field. That means ruggedization of a fiber laser system against shock, vibration, moisture and environmental extremes, plus the structure, thermal management and precision packaging around the laser head and beam director. You'll work hands on from architecture through bench validation, field correlation and the production handoff to our Detroit manufacturing hub, alongside our Staff and Principal engineers.
What You'll Own:
Mechanical design of major subsystems: laser source and head enclosures, gimbal and beam director structure, mounts
Survivability to MIL-STD shock, vibration, humidity, dust and austere environments
Thermal management for high-power laser and electronics packaging
Precision and optomechanical packaging that holds alignment through shock and thermal cycles
FEA (static, modal, random vibration, shock response spectrum) and correlation to test
Test rigs, instrumentation and bench validation you build and run yourself
DFM and the handoff to manufacturing in Detroit
Design reviews and raising the bar for the junior ME team

Required

5+ years in mechanical engineering on ruggedized, field-deployable or high-performance systems
At least one subsystem you took from prototype to production
Strong FEA (ANSYS, Nastran, Abaqus or equivalent) and the bench work to back it up
Hands-on design to MIL-STD-810 or equivalent shock and vibration standards
Thermal design for high-power systems
Evidence you learn fast. You got effective in a new domain in months, not years
Where you probably come from: Defense hardware, airborne or ground vehicle systems, F1 and high-performance automotive, aerospace, maritime, ruggedized electronics, or directed energy and field-deployed sensor programs. Domain matters less than shipping hardware that had to survive.
We want to talk if: You've owned a system that had to survive shock, vibration and environmental extremes in a tight, deployable package, and you modeled it, built it, instrumented it and correlated it.
Not a fit if: You've only done commercial or consumer product design, your work is simulation-only with no bench validation, or you've spent years on one narrow subcomponent without seeing the system around it.

Preferred

Laser, directed energy or high-power hardware
Optical bench or precision instrument ruggedization
MIL-STD-461 EMI/EMC awareness for mechanical integration
Vehicle-mounted systems
Manufacturing ramp experience
Education: BS or MS in Mechanical, Aerospace or related field. What you've built matters more than where you went to school.
How You Operate:
Extreme bias for action. You'd rather build a prototype tomorrow than model it for a month
