Senior Siemens NX CAM Programmer (U.S. Citizenship Required

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 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.

Key Responsibilities:

• 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.

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 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 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
  work holding and fixturing principles
  for complex geometries.

Preferred Qualifications:

• Experience in an
  AS9100 aerospace manufacturing environment
  .
• Familiarity with
  Grob 5-axis platforms
  and trunnion-style or horizontal 5-axis machining.
• Experience with
  post processor tuning
  or close collaboration with post developers.
• Knowledge of
  high-efficiency machining (HEM)and advanced cutting strategies.
• Experience with
  NX CAM automation tools
  , such as templates, feature-based machining, or custom scripting.

Soft Skills:

• Strong
  ownership mentality
  with a proactive, solution-oriented…
