What is Aurelius Systems?

Aurelius Systems is a directed energy company developing edge-deployed laser systems for cUAS applications

We shoot down drones with laser guns

Why?

The US and our allies have prepared for a world where we will be fighting increasingly large and sophisticated systems (Planes, Aircraft carriers, etc), but this world never came. The future of warfare will involve large numbers of small-scale and mass-manufacturable drones, and we aren’t prepared to defend our country from these threats abroad or domestically. Aurelius Systems has set out to address this problem by equipping the US and our allies with the systems they need to fight current and future conflicts in a scalable and cost-effective manner.

Job Description

We are seeking an inventive Hardware Engineer to drive structural and thermal analysis and design for rapid prototyping of our laser defense systems. You will lead finite element analysis (FEA), thermal management, vibration and robustness testing, and prototype validation to deliver rugged, field‑ready hardware. This role spans concept through production, emphasizing a strong bias toward hands‑on testing and iterative mechanical prototyping in demanding defense environments.
