Every morning since 2013, Kelli Joachim has boarded the same gray, steel-hull, guided-missile destroyer floating in San Diego Bay - USS John Paul Jones. She pulls the same tattered pair of navy blue, grease-stained coveralls out of her stand-up locker in the female berthing and slides into them.

The 20-year-old Las Vegas native doesn't fit the mold of a "prototypical" electrical engineer, and she knows it.

"I'm a lot smaller than most of the people I work with, but that's alright. I work just as hard, I'm a fast learner and I bring a positive attitude to the workplace," she said.

She's five foot nothing, probably weighs 100 pounds soaking wet, and is in a perpetual state of happiness. While most of her peers sit behind desks and in front computers to complete a day's work, her workplace of choice is in the heart of the ship, and her tools of choice are wrenches and screwdrivers.
