The Role The Mechanical Design Engineer will be a member of the hardware team responsible for the mechanical design of our Quantum Key Distribution (QKD) systems. Tasks will include designing custom 19-inch rack-mounted enclosures (sheet metal), the internal mechanical parts that carry our boards and optics, and housings for internal modules. You will take designs from concept through 3D CAD, design-for-manufacture, prototyping, fabrication, and integration, working hands-on with sheet-metal and CNC suppliers.

We currently use Fusion 360 but are open to your preferred tool.
