Hardware hiring managers care deeply about manufacturing costs. State exact percentages saved on components or production revisions.
Mention specific equipment like spectrum analyzers and oscilloscopes to prove your hands-on lab competency.
Link your schematic capture and Altium work directly to metrics like reduced transmission errors or lower crosstalk.
Name exact layers, device families like Xilinx FPGAs, and protocols rather than speaking in general electronics terms.
