I am a Manufacturing Process Engineer (MPE)

In the previous article, we talked about the roles and responsibilities of an MPE (Manufacturing Process Engineer). Now, let’s look at what an MPE actually does day to day in a company.

MPE and R&D Are One Team During Pilot Runs

When a new product goes into a pilot run, MPE works as part of the same team as R&D.

During the pilot run stage, MPE helps R&D handle all kinds of unexpected assembly engineering issues. New products almost always run into surprises—maybe the PCB was designed with a wrong circuit trace, so the product can’t even power on. In that case, MPE coordinates with the factory to cut traces or add jumper wires.

Today, I want to introduce the responsibilities and role of MPE (Manufacturing Process Engineering). It’s a bit awkward because Workingbear’s own job is exactly this—MPE work. If you’ve read through this blog, you can probably guess that MPE’s responsibilities cover a huge range of tasks. You could say Workingbear knows a lot of different technologies from design to manufacturing, but isn’t necessarily a deep expert in every single one. How deep the expertise goes really depends on how much time, effort, and understanding each person invests.

Here, the “Testing Engineer” we’re talking about is the one in a manufacturing plant responsible for product testing. We usually refer to the R&D engineers responsible for testing as EEs (Electronic Engineer). This role, along with the “Process/Product Engineer” we mentioned earlier, is one of the must-have positions in a factory. Another key role is the “Quality Engineer.” Together, they form what’s often called the “iron triangle” of a factory’s engineering department.
