Assist in the mechanical design of antenna structures, enclosures, radomes, and mounting hardware using 3D CAD.

Support structural, thermal, and environmental analysis (such as FEA, vibration, and ingress protection) of rugged products for field use, including counter-UAS systems.

Help build, assemble, and test prototypes, and work with suppliers on machined, sheet-metal, composite, and 3D-printed parts.

Prepare manufacturing drawings, bills of materials, and documentation, and share your findings with the team. Thesis workers will also complete their master’s thesis on a topic linked to our product development.
