RTC Aerospace•Fife, WA

22h•Onsite

About The Position

RTCA is a precision aerospace and defense manufacturing group built on decades of hands-on machining expertise, with roots spanning more than 50 years. They support mission-critical commercial and government aerospace programs across North America through four U.S. Centers of Excellence, operating as an integrated platform with 150+ CNC machines and a team of 250+ professionals. Unlike large organizations, RTCA offers hands-on ownership and real visibility, allowing employees to understand how their work supports the team, the operation, and the end customer. Their flat structure encourages initiative, skill growth, and recognition of contributions, while providing the stability, advanced technology, and meaningful work of an established aerospace manufacturer. At RTCA, they believe in teamwork, excellence, and delivering with pride. The 5 Axis Mill Setup Machinist is responsible for independently setting up and operating CNC machines to produce precision aerospace components. This role requires a strong understanding of feeds, speeds, and tooling to improve operational efficiency and ensure conformance to specifications. Working closely with Quality, Engineering, and Operations, the CNC Setup Operator II contributes to continuous improvement while maintaining high standards of safety, accuracy, and productivity.

Requirements

Minimum 3 years of CNC setup and operating experience in a manufacturing environment.
Strong knowledge of feeds, speeds, and tooling for aerospace-grade metals and alloys.
