Job Title: CNC Setup Machinist
This role focuses on performing complete setups and operation of 3- and 5-axis CNC milling machines to produce prototype and production parts from solid models, blueprints, and engineering drawings. You will independently set up tooling and fixtures, verify first articles, and make program edits at the machine using Heidenhain controls to ensure high-quality, precise components for advanced manufacturing projects.
Perform complete short-run CNC mill setups on 3- and 5-axis machines, including tooling selection, fixture setup, setting offsets, and first-article verification.
Set up and run 3- and 5-axis CNC milling machines for both prototyping and production runs across a variety of materials such as aluminum, steel, and graphite.
Edit Heidenhain programs at the machine, including adjusting offsets, modifying feeds and speeds, and making minor code changes as needed.
Apply sound machining principles, including appropriate cutting methods, feed and speed selection, and proper tool selection for each job.
Perform in-process and final quality inspections using precision measuring tools to confirm parts meet dimensional and tolerance requirements.
Troubleshoot machining and program issues at the machine, making necessary adjustments to maintain part quality and productivity.
Handle multiple setups per day in a fast-paced environment, efficiently transitioning between different jobs and part configurations.
Collaborate with team members and support staff to ensure smooth workflow, clear communication, and on-time delivery of parts.
Minimum of 3 years of experience performing full CNC mill setups on 3- and 5-axis machines, including tooling selection, fixturing, setting offsets, and verifying dimensions.
Strong hands-on experience setting up and running CNC milling machines for both prototype and production work.
Proficiency working independently with Heidenhain controls, including editing programs at the machine, adjusting offsets, modifying feeds and speeds, troubleshooting, and making minor code changes.
Solid understanding of machining principles, including cutting methods, feed and speed selection, and tool selection.
Experience using precision measuring tools to perform quality inspections and verify tight tolerances.
Reliable work habits and consistent attendance to support production schedules and team needs.
Experience in prototype machining, particularly for automotive or aerospace applications.
Familiarity with aerospace machining requirements and standards.
Knowledge of WorkNC or similar CAM software.
Previous experience in environments focused on prototypes, tooling, and fabrication for OEM or Tier 1 suppliers.

The company offers exposure to advanced and complex machining, including full 3-axis setups with opportunities to work on 5-axis machines and a wide range of materials. Growth and expansion into aerospace and military projects provide challenging, high-level work and strong long-term stability. Team members benefit from a climate-controlled facility, overtime opportunities, full health benefits, paid time off, a 401(k), competitive compensation, and on-the-job training that supports continuous skill development and career growth.
The role is based in a climate-controlled machine shop within a large manufacturing operation of over 100,000 square feet, divided into multiple buildings. The environment is high-paced and focused on automotive and aerospace prototypes, tooling, and fabrication for OEM and Tier 1 supplier work. You will work primarily with 3- and 5-axis CNC milling machines using Heidenhain controls, with exposure to additional technologies such as Fanuc, Fidia, and WorkNC where applicable. Standard hours are on first shift, from 6:00 a.m. Monday through Friday, with regular Saturday work from 6:00 a.m. The shop is organized to support multiple setups per day and high-mix, low-volume work, providing a structured yet dynamic manufacturing environment.
