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 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.
