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.

The
Senior Siemens NX CAM Programmer
will be responsible for developing, optimizing, and standardizing CNC programs for3-, 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.

• Develop and optimize
  CNC programs in Siemens NX CAM
  for complex components requiring tight tolerances and high surface integrity.
• Program3-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.

• 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
  .

• 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.

• 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.).

• 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 programming3-, 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 alloys
  (high-speed machining and finishing…
