Entegris careers

Entegris makes the unglamorous materials that chipmaking can't run without: filtration products, gas delivery systems, specialty chemistries, wafer carriers, coatings, graphite, and silicon carbide components. The company works from headquarters in Billerica, Massachusetts, with manufacturing, R&D, and support sites placed near customers worldwide and about 7,700 employees per its 2025 corporate overview. The same overview puts net sales at roughly $3.2 billion for 2025, with about $329 million of it plowed into R&D. Microelectronics is the anchor market, and the same materials work reaches industrial, pharmaceutical, and medical device customers.

The lineage goes back to 1966 and a company called Fluoroware; the Entegris of today took shape in a 1999 merger. That history is worth reading for culture. This is a firm that has spent decades on contamination, purity, and handling problems most people never hear about, and it holds around 4,400 active patents for its trouble. Semiconductors are the center of gravity, but the same materials science serves industrial, pharmaceutical, and medical device customers. A company selling purity to chipmakers runs on process discipline, and that discipline shapes the working environment more than any perk list would. The corporate overview frames the footprint as strategically placed manufacturing sites, R&D facilities, and customer support centers, and that geography stands behind most of its hiring.
