Who We Are:
/p
Aurelius Systems is a VC backed defense tech startup building autonomous, edge deployed directed energy systems for counter-UAS. We build laser weapons to shoot down drones.
pWe're a small team of engineers, former US military operators, and subject matter experts scaling America's directed energy dominance. The first cost effective, reliable and robust laser weapon system. pOur namesake isn't an accident. Marcus Aurelius wrote about doing the work in front of you, every day, without excuses.Henry Ford didn't wait for permission to reinvent manufacturing. That's how we operate — small team, unreasonable output, no hiding behind the unachievable. pIn addition to our San Francisco lab, we’ve opened a Detroit manufacturing hub and we field test weekly on our own 400-acre private range. he Role and Your Impact: pWe need a Mechanical Engineer focused on design ruggedization across Archimedes — survivability across shock, vibration, moisture, and environmental extremes for a fiber laser system in a deployable, field-rugged package.
MIL-spec is one of the harder problems in directed energy and a make-or-break domain for the platform. You'll work hands on from architecture through bench validation and field correlation. hat You'll Own: ul li
Structural and mechanical design for survivability across MIL-STD shock, vibration, humidity, dust, and austere environments
liRuggedization architecture across the laser source, laser head, and supporting subsystems
liSealing, ingress protection, and moisture/corrosion mitigation strategies (IP ratings, conformal coatings, gasket design)
liVibration isolation system design including isolator selection, snubbing, and modal analysis
liShock analysis and design including fragility assessment, cushion design, and drop/transportation survivability
liFEA modeling including static, modal, random vibration, and shock response spectrum analysis
liStructural validation including instrumentation, test rigs, and correlation to model
liTrades between ruggedization performance, mass, stiffness, and packaging across the system
/ul hat We're Looking For: ul li3 to 10+ years in mechanical engineering on ruggedized or field-deployable systems
liStrong FEA experience with ANSYS, Nastran, Abaqus, or equivalent
liHands on experience designing to MIL-STD-810 or equivalent shock and vibration standards
liTrack record building and instrumenting structural test rigs and correlating model to bench
liExperience with sealing, EMI/EMC gaskets, conformal coating, and environmental protection design
liExperience designing enclosures and structures for field-deployable or military conditions
/ul here you probably come from: pDefense hardware companies, airborne or ground vehicle systems, ruggedized electronics enclosures, directed energy programs, or field-deployed sensor or radar systems. e want to talk if: pYou've designed a system that had to survive shock, vibration, and environmental extremes in a constrained, deployable package. You can model it, build it, instrument it, and correlate it.ot a fit if: pYou've only done commercial or consumer product design, your work is simulation-only with no bench validation, or you've never designed to a MIL or DO-160 standard. ice to Haves: ul li
Direct laser system or directed energy hardware experience
liMIL-STD-461 EMI/EMC design awareness for mechanical hardware integration
liExperience with optical bench or precision instrument ruggedization
liField-deployable or vehicle-mounted system experience
/ul ducation: ul liBS or MS in Mechanical, Aerospace, or related engineering field. PhD welcome but not required.
/ul ow You Operate: ul liExtreme bias for action. You'd rather build and instrument the rig tomorrow than model it…
