What we need

We are looking for a hands-on, detail-oriented Machinist to join our Fixtures & Prototypes team within the System Test organization. Your job will be to bring prototypes, machines, tools, and fixtures from concept to completion. You will collaborate with engineers to influence and optimize designs, fabricate custom, low-volume, and one-of-a-kind parts and components in our machine shop, and build fixtures.

You will operate, program, and set up manual and CNC machines to produce metal and plastic parts based on engineering drawings and specifications. You will also take ownership of maintaining shop equipment and managing machine schedules. This is a dynamic position that blends creativity, design, and problem-solving with hands-on machining, assembly, and maintenance.

What we do

The Fixtures & Prototypes team is part of the System Test organization. The team collaborates with engineers to optimize designs and bring prototypes, machines, tools, and fixtures from concept to completion through machining, fabrication, assembly, and maintenance.

What you'll do

• Analyze complex engineering drawings, CAD/CAM files, sketches, and blueprints to understand dimensions, tolerances, and job specifications.
• Select and install the proper cutting tools, fixtures, and raw materials, and write, edit, and prove out CNC machine programs, including G-code and M-code programming.
• Perform turning, milling, drilling, and shaping operations to produce custom, low-volume, and one-of-a-kind parts to exact tolerances, using precision measuring instruments to verify that first and final pieces meet quality standards.
• Collaborate with engineers early in the design process to influence and optimize designs for manufacturability, quality, and efficient machining.
• Work cross-functionally with engineering teams to fabricate parts and components and bring prototypes, machines, tools, and fixtures from concept to completion.
• Use hands-on machining expertise and shop-floor feedback to influence engineering decisions, identify design improvements, and solve complex prototype and fabrication challenges.
• Perform daily preventive maintenance, manage machine schedules, and maintain a clean, organized, and safe work area.

What you'll need

• High school diploma or GED and 8 or more years of experience as a machinist working with manual and CNC machines; vocational or technical training or a completed apprenticeship is highly preferred.
• Experience with CNC software such as CAMWorks or familiarity with other CNC machining software, including Mastercam or Fusion 360.
• Experience working with ProtoTRAK and Haas machines and controls.
• Experience with waterjet machines and/or laser cutting equipment.
• Strong understanding of machining principles, geometric dimensioning and tolerancing (GD&T), and the properties of various metals.
• Advanced shop math and analytical skills, including the ability to calculate feeds, speeds, dimensions, and tolerances.
• Experience with Solid Works CAD software and familiarity with Microsoft Word and Excel; relevant certifications are a strong plus.

Our environment

• There will be steep stairs to climb into the struct ure . You may be required to routinely walk up and down stairs to navigate the automation structure.
