Senior Siemens NX CAM Programmer

About Us:

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.

Position Summary:

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.

Key Responsibilities:

• Develop and optimize CNC programs in Siemens NX CAM for complex components requiring tight tolerances and high surface integrity.
• Program 3-axis, 4-axis, and full 5-axis simultaneous milling operations across multiple machine platforms (Grob, Kitamura, Okuma, Mazak, Haas).
• Establish and maintain programming standards and best practices
  , including toolpath strategies, naming conventions, and documentation structure.
• Create comprehensive setup documentation
  , including tool lists, setup sheets, work holding requirements, and process notes to ensure repeatability on the shop floor.
• Analyze and refine machining processes with a focus on process stability, cycle time reduction, and tool life optimization
  .
• Select and validate cutting tools, toolpath strategies, and fixturing/work holding approaches based on material, geometry, and production requirements.
• Manage, optimize, and verify NX Post-Processors across all machine platforms.
• Apply data-driven methodologies to evaluate machining performance and guide continuous improvement efforts.

Process Optimization & Continuous Improvement:

• Lead initiatives to optimize existing part families
  , focusing on incremental gains in efficiency, consistency, and cost reduction.
• Identify opportunities to implement advanced toolpath strategies (e.g., high-efficiency milling, adaptive clearing, multi-axis finishing techniques).
• Drive adoption of advanced NX CAM capabilities
  , including parametric programming, feature-based machining, and template-driven workflows.
• Collaborate with engineering, machinists, and quality teams to validate and refine machining processes
  .

Tooling, Libraries, and Systems Development:

• Support the development and implementation of a tool management system
  , including tool tracking, standardization, and lifecycle management.
• Define and maintain resident tool libraries within NX and shop floor systems to ensure consistency and reduce setup variability.
• Standardize tooling packages across similar part families to improve efficiency and reduce cost.

Automation & Digital Manufacturing:

• Develop and implement automation strategies within NX CAM
  , including templates, reusable operations, and parametric programming approaches.
• Demonstrate a track record of automating repetitive programming tasks to improve programming efficiency and reduce variability.
• Support integration of CAM workflows with broader digital manufacturing systems (MRP, tool management, etc.).

Required Qualifications:

• 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)
• Aluminum…
