Introduction to the role

ASML US, LP brings together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, and more energy-efficient microchips. We design, develop, integrate, market, and service these advanced machines, which enable our customers-the world's leading chipmakers-to reduce the size and increase the functionality of their microchips. This, in turn, leads to smaller, more powerful consumer electronics. Our headquarters are in Veldhoven, the Netherlands, and we have 18 office locations across the United States, including main offices in Wilton, CT; Chandler, AZ; and San Jose, CA.

ASML is the world's leading provider of lithography systems for the semiconductor industry, manufacturing complex machines that are critical to the production of integrated circuits or microchips. This position is for a First Line Support Production Engineer with an innovative mindset to join the Production Engineering department at our Wilton Factory. The candidate will collaborate across sectors to provide rapid response to resolve disturbance notices related to engineering issues and execute the engineering steps listed in the Production Operator Dashboard (POD) to support output.
