Sales Assistant

HYE USA is expanding its U.S. market presence and diversifying beyond its core semiconductor client base. As part of this growth, we are hiring a Sales Assistant to support our Local Sales / New Account Business Development effort. This role is not a back-office support position, it is a front-line, execution-focused role responsible for opening new customer relationships in the U.S. market and connecting those opportunities into HYE USA's internal sales and estimating process.

You will work directly with the Sales Lead for coaching and strategic direction, and with the Estimator & Technical Support lead to move qualified opportunities into proposals. Over time, this role is expected to grow from customer access and relationship-building into full ownership of small and mid-size project pursuits.
