"Helped design circuit boards and tested prototypes" is the electrical-engineering equivalent of white noise — every EE resume says some version of it. What actually separates a strong electrical resume is naming the board type, the tools you used to find and fix the hard problem, and what happened as a result — a certification passed, a defect eliminated, a cost cut.
Below are before/after examples across common electrical engineering scenarios, plus keywords worth naming. See the full ATS-friendly resume guide for the underlying bullet-writing formula.
Before / after examples
Illustrative examples — write your own numbers from your actual work; approximate is fine, invented is not.
PCB design / EMC compliance
// beforeHelped design circuit boards and tested prototypes.
// afterDesigned and validated a 4-layer PCB for a motor-control board (STM32 + FOC), resolving EMI issues found in pre-compliance testing and enabling first-pass EMC certification.
Power electronics
// beforeWorked on power supply design for a new product.
// afterDesigned a synchronous buck converter delivering 5A at 3.3V, improving efficiency from 82% to 94% and reducing thermal derating margin issues in the enclosure.
Debugging / signal integrity
// beforeDebugged issues found during hardware testing.
// afterDiagnosed a signal integrity issue on a high-speed differential pair using a scope and TDR, eliminating a bit-error fault that had blocked production release.
Cost / component reduction
// beforeWorked with the team to reduce the bill of materials cost.
// afterConsolidated discrete power components into a single PMIC, cutting BOM cost by $1.80/unit across a 100k-unit annual volume.
FAQ
Should I include EMC/compliance testing experience even if I wasn't the lead?
Yes — note your role in it specifically (e.g. "supported pre-compliance EMC testing") rather than omitting it. Compliance exposure is a differentiator even in a supporting role.
Analog or digital — should I specialise on my resume?
State your actual strength clearly in the summary line rather than presenting as a generalist. A named specialty (power electronics, RF, mixed-signal) is easier for a recruiter to match to a role than "electrical engineer" alone.
