Physical demands & Abilities:This is a hands-on role, with most of the time spent on the production floor and within manufacturing environments supporting equipment troubleshooting, repair, preventative maintenance, and continuous improvement activities. The role also includes routine computer work, documentation, and coordination with cross-functional teams. The position requires standing, walking, bending, and climbing ladders, as well as the ability to perform repetitive tasks and maintain focus for extended periods. Manual dexterity is required to assemble, adjust, and repair equipment with accuracy and precision. Specific vision abilities include close vision, distance vision, color vision, peripheral vision, depth perception, and the ability to adjust focus.

Work may involve exposure to chemicals, fumes, noise, and manufacturing materials. Use of personal protective equipment (PPE), including safety glasses, gloves, protective clothing, and respiratory protection, is required in designated areas or when performing specific tasks. The ability to wear required respiratory protection is an essential function of the role. The position requires the ability to lift up to 44 pounds (20 kg) and safely operate manufacturing equipment, maintenance tools, and factory machinery. Occasional extended hours or schedule flexibility may be required to support production demands, audits, or investigations.
