I am a Controls Engineer for Oral-B Laboratories (part of P&G). I work on the automation systems that create and package toothbrushes. We produce something like 400,000,000 toothbrushes a year here and supply most of North America. My job is a mix of design (creating electrical schematics, modifying PLC programs, installing vision systems) and support (troubleshooting software bugs, helping electricians, reading through datasheets). It's interesting because I have a cubicle but the manufacturing is also on site, and I get a lot more hands on involvement debugging machines than one might expect for an engineering role. Some days it's like working in the pits at an FRC regional, which can make it a challenge to get your "real work" done.
My usual response to "what do you do?" is "I make toothbrushes all day"
FIRST experience has really helped me out because I actually knew something about relays, servos, vision, and motion control coming in. Most of the people in my college classes didn't know what a relay was due to the courses being so focused on things you'd see in the semiconductor industry. Once you explain that a relay is basically a power MOSFET a relay makes sense, but FIRST experience allowed me to skip some of that learning curve. Being a part of a FIRST team also gave me some good answers for interview questions.
