Meet Rachelle Sorenson, senior associate chemical engineer

“I’ve had two completely different experiences in the two years I have been here at Caterpillar. I’ve worked in a manufacturing plant and currently I am in Aftertreatment research. I don’t know what will come next, but I know it will be something totally different and exciting.” 

This is how Rachelle Sorenson, senior associate chemical engineer in the Engineering Rotational Development Program, summarized her Caterpillar career experience thus far. 

While many chemical engineers end up working for oil companies, it was the opportunity to work in one of our manufacturing facilities that first attracted Rachelle to Caterpillar. In Rachelle’s first rotation she provided 24/7 support of  chemicals, such as metal working fluids, oils and lubricants, utilized in machining parts for Undercarriage and Advanced Components and Systems Division in East Peoria, Ill. 

Now in her second rotation, Rachelle is working in research for the Aftertreatment group. She’s involved in several projects, such as working to simulate real life processes to test catalysts and also assisting on a methane sensor project.  

“Now that I am in research, I get to try new ideas. It is exciting to be working with people as they are developing new ideas,” said Rachelle.  

While Caterpillar is known for quality products, it’s the people that Rachelle says make her proud to work for Caterpillar.  

“Caterpillar is known worldwide for our quality product, but we’re also known for our hard work and getting the task done. Everyone works to make sure Caterpillar succeeds and that is why I am proud to work here.”

Outside of work, Rachelle stays busy by training for her third half-marathon.
