Senior Manufacturing Engineer – CNC Programming (Aerospace) in Sidney, Ohio at DRT Holdings, LLC

Build What Powers the Future of Flight, Defense, and Space

We are seeking a Senior CNC Programmer / Manufacturing Engineer with advanced Siemens NX (Unigraphics) CAM programming experience to support complex aerospace manufacturing programs. This role focuses on 3‑axis, 4‑axis, and 5‑axis CNC programming, machining strategy, and process engineering for tight‑tolerance aerospace components.

This position requires the ability to reliably commute to the work location. Relocation assistance is not available.

Why This Role Matters

This is a true engineering ownership position—not a support role. You will define how complex aerospace components are manufactured from concept through production, directly influencing quality, efficiency, and manufacturability.

What Great Looks Like Here

• You don’t just edit programs—you build them from scratch

• You understand machining behavior, not just toolpaths

• You thrive solving real problems on the shop floor

• You’ve worked in high-precision or aerospace environments

What You’ll Do

• Develop 3‑axis, 4‑axis, and 5‑axis CNC programs using Siemens NX (Unigraphics)

• Create toolpaths, machining strategies, and optimized cutting parameters

• Interpret blueprints, engineering drawings, and GD&T

• Select tooling, determine speeds/feeds, and define machining processes

• Support simulation, prove‑outs, and troubleshooting on the shop floor

• Improve cycle times, machining efficiency, and process reliability

• Create setup sheets, documentation, and process instructions

• Support AS9100 aerospace quality and manufacturing standards

Requirements

• 5+ years of CNC programming experience (3‑axis minimum)

• Strong proficiency with Siemens NX / Unigraphics

• Ability to build programs from scratch

• Strong understanding of machining processes, tooling, and materials

• Solid GD&T and blueprint reading skills

Preferred

• 5‑axis CNC programming experience

• Aerospace or defense manufacturing experience

• Experience with Mastercam or AutoCAD

• Lean / continuous improvement background

• ERP/MRP system exposure

Why DRT Aerospace

• Work on high-impact aerospace and defense programs

• Advanced CNC machining technology and metrology systems

• Strong focus on Lean manufacturing and Industry 4.0 transformation

• Collaborative, high-performance engineering culture

• Career growth into:

  • Manufacturing Engineer

  • Advanced Manufacturing / Automation roles
