Job description

Senior Siemens NX CAM Programmer - manufacturing - job employment

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.

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).
• Extensive experience machining a range of materials, including: 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.

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 approach.
• Highly analytical and detail-oriented, with a focus on precision and repeatability.
• Excellent technical writing skills.
• Effective communicator, able to collaborate across programming, machining, and engineering teams.
• Comfortable operating in a process-driven, continuous improvement environment.
• Ability to balance hands-on programming work with strategic process development.

Why Join Us:

• Work on high-precision aerospace components using advanced multi-axis machining platforms.
• Play a key role in shaping programming standards and manufacturing strategy.
• Be part of a team focused on deep process optimization, not just high part turnover.
• Engage with complex technical challenges that require both creativity and rigor.
