Pros

I was at first hired by Aptina, which was later acquired by ON Semi. In total, the R&D group is small (10 people), have to do a lot to assist both the hardware and software team. It was still running as Aptina, where you can learn a lot from everyone in the team.

Cons

It has 401k match, but the health insurance plan is really bad. Communication between different groups is mostly slow and sometimes you have to find out the answer yourself.

The company is focused on meaningful, long‑term impact, and you truly feel that the work you do matters—especially given onsemi’s role in power, automotive, and industrial technologies.

Like many large global companies, alignment across regions and functions can take time.

Pros

Coworkers, if any are left. Benefits are standard. Good place to start, get a few years experience and then run,

Cons

management by spreadsheet. You are a cog in the wheel, and only that. The new plant manager is a carpet bagger who won't stay long term and has no desire to do so, Plays whack a mole with employees, so all the senior staff is gone. I worked here a long time for different masters, this is as bad as it can get. There is no career path here. The company doesn't expect you to want one.
