In addition, MACOM offers foundry services that represent a key core competency within our business.

MACOM sells and distributes products globally via a sales channel comprised of a direct field sales force, authorized sales representatives and leading industry distributors. Our sales team is trained across all of our products to give our customers insights into our entire portfolio.

As a Principal Test Engineer at MACOM, you will partner with Device Integration, Product Engineering, and Technology Development teams to develop and deploy wafer-level test procedures at MACOM’s semiconductor foundry in Lowell, MA. You will be challenged by a diverse mix of product technologies, as MACOM serves a broad spectrum of high-performance markets “from RF to light”. You will be responsible for developing new device test procedures and supporting their seamless transition into the production test environment.

Your skills and knowledge related to DC and RF test and measurement instruments and methods will be key to your success, as will your attention to detail, ability to communicate ideas and your passion for excellence.
