Job Description:

Job Overview

Responsible for developing, programming, and sustaining CNC lathe machining processes within a precision manufacturing environment. This role focuses on CNC turning (including live tooling), SolidWorks modeling, CNC CAM programming (Mastercam/Esprit), process development, and production support to ensure efficient, repeatable, and high-quality manufacturing. Primary objective is to improve machining efficiency, reduce cycle time, and support on-time delivery through robust process design and hands-on shop floor execution.

Please note: This position may involve working with technical data, technology, software/source code, hardware, or other items (collectively “items) subject to U.S. and non-U.S. export control laws and regulations. Under these regulations, it may be necessary for TE to verify a candidate’s national origin and/or citizenship status to determine whether a U.S. or other government export license is required prior to releasing its technologies to the candidate. If TE determines that TE will require a license or will be prohibited by applicable laws from providing the candidate with items necessary for the performance of this position, then TE expressly reserves the right to either a) make an offer of employment contingent upon TE receiving required export licenses from the appropriate government agency, b) consider the candidate for a different position that is not subject to such restrictions, on whatever terms and conditions TE shall establish in its sole discretion, or c) decline to move forward with the candidate’s application.
