• Establish and maintainprogramming standards and best practices , including toolpath strategies, naming conventions, and documentation structure.
• Create comprehensivesetup 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 onprocess stability, cycle time reduction, and tool life optimization .
• Select and validatecutting tools, toolpath strategies, and fixturing/work holding approaches based on material, geometry, and production requirements.
• Manage, optimize, and verifyNX Post-Processors across all machine platforms.
• Applydata-driven methodologies to evaluate machining performance and guide continuous improvement efforts.

Process Optimization & Continuous Improvement:

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

Tooling, Libraries, and Systems Development:

• Support the development and implementation of atool management system , including tool tracking, standardization, and lifecycle management.
• Define and maintainresident 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 implementautomation strategies within NX CAM , including templates, reusable operations, and parametric programming approaches.
• Demonstrate a track record ofautomating repetitive programming tasks to improve programming efficiency and reduce variability.
• Support integration of CAM workflows with broaderdigital manufacturing systems (MRP, tool management, etc.).

Required Qualifications:

• 10+ years of CNC programming experience , with a strong focus on multi-axis milling.
• Advanced expertise inSiemens NX CAM , including complex multi-axis toolpath generation and post-processing considerations.
• Proven experience programming3-, 4-, and 5-axis machining centers .
• Deep understanding of machiningtight-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 ofcutting tools, tool coatings, and tool life optimization strategies .
• Experience developingsetup documentation, tool lists, and standardized processes .
• Demonstrated ability toanalyze and optimize machining processes using data .
• Strong understanding ofworkholding and fixturing principles for complex geometries.

Preferred Qualifications:

• Experience in anAS9100 aerospace manufacturing environment .
• Familiarity withGrob 5-axis platforms and trunnion-style or horizontal 5-axis machining.
• Experience withpost processor tuning or close collaboration with post developers.
• Knowledge ofhigh-efficiency machining (HEM) and advanced cutting strategies.
• Experience withNX CAM automation tools , such as templates, feature-based machining, or custom scripting.

Soft Skills:

• Strongownership mentality with a proactive, solution-oriented approach.
• Highlyanalytical 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 aprocess-driven, continuous improvement environment .
• Ability to balancehands-on programming work withstrategic process development .

Why Join Us:

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