Senior Siemens NX CAM Programmer

Davis Manufacturing•Arvada, CO

2d•Onsite

About The Position

We are an AS9100-certified contract manufacturer delivering advanced machining solutions to the aerospace and defense industry. Our core competency lies in producing complex, high-precision components with a strong emphasis on process optimization, repeatability, and efficiency. Unlike high-mix environments, we focus on refining and scaling established part families, driving continuous improvement in machining performance and cost. The Senior Siemens NX CAM Programmer will be responsible for developing, optimizing, and standardizing CNC programs for 3-, 4-, and 5-axis milling operations across a range of advanced machine platforms, including Grob, Kitamura, Okuma, and Mazak. This role requires deep expertise in Siemens NX CAM, strong machining fundamentals, and the ability to make data-driven decisions related to toolpaths, tooling strategies, and work holding. The ideal candidate will play a critical role in advancing programming methodologies, improving process efficiency, and establishing best practices across the organization.

Requirements

10+ years of CNC programming experience, with a strong focus on multi-axis milling.
Advanced expertise in Siemens NX CAM, including complex multi-axis toolpath generation and post-processing considerations.
Proven experience programming 3-, 4-, and 5-axis machining centers.
Deep understanding of machining tight-tolerance aerospace components.
Expert understanding of GD&T (ASME Y14.5) and the ability to translate dimensional requirements to a stable and efficient machining process.
Extensive experience machining a range of materials, including: High-strength alloys (e.g., alloy steels, tool steels, nickel-based alloys) and Aluminum alloys (high-speed machining and finishing strategies).
Strong knowledge of cutting tools, tool coatings, and tool life optimization strategies.
Experience developing setup documentation, tool lists, and standardized processes.
Demonstrated ability to analyze and optimize machining processes using data.
Strong understanding of workholding and fixturing principles for complex geometries.
US Citizenship or Permanent Residency Required.
