Job description

Smart4Chemicals are recruiting for a leading aerospace manufacturing business for a Senior CNC Programmer / Engineer based at their facility in Sylmar, California.

This is an excellent opportunity for an experienced CNC professional to take a leading role in CNC programming, process planning, tooling, machine selection, and continuous improvement across multi-axis CNC machining operations.

You will be responsible for developing and optimizing machining strategies for precision plastic transparencies, composites, and aerospace tooling components, while evaluating new technologies and equipment to improve manufacturing capability, quality, efficiency, and cost.

Key Responsibilities

• Develop, modify, and optimize CNC programs for 3-, 4-, and 5-axis milling machines
• Support the manufacture of precision plastic transparencies, composites, and aerospace tooling components
• Utilize CAD/CAM software including Mastercam, Siemens NX, CATIA, or similar
• Design and qualify cutting tools, fixturing, and work-holding solutions
• Establish and optimize machining parameters, coolant/lubrication strategies, and machining processes
• Drive improvements in tool life, dimensional accuracy, surface finish, process reliability, and production efficiency
• Utilize CNC simulation and verification software such as VERICUT for program validation and collision avoidance
• Interpret technical drawings, GD&T, and 3D CAD models to develop accurate toolpaths
• Research and implement emerging machining technologies, tooling solutions, and industry best practices
• Work with suppliers and attend industry events to benchmark and identify new manufacturing technologies
• Evaluate and recommend new CNC machinery and equipment to support future manufacturing capability
• Support capital investment decisions and continuous improvement initiatives across the facility
• Ensure machining processes meet AS9100 and relevant aerospace industry standards

Qualifications

• Bachelor's Degree in Manufacturing or Mechanical Engineering preferred
• 7+ years' experience in CNC programming and machining within aerospace, defence, or other high-precision manufacturing environments
• Strong experience with 3-, 4-, and 5-axis CNC machining, ideally including plastics machining
• Experience with CNC platforms such as Zimmermann, CMS, Makino, DMG MORI, Mazak, Okuma, or Haas
• Strong knowledge of CATIA.
• Strong G-code and M-code programming experience
• Knowledge of GD&T / ASME Y14.5 and precision blueprint interpretation
• Experience working to aerospace quality standards, particularly AS9100, is highly desirable
• Technically curious with a strong interest in emerging machining technologies and process optimization

Salary: $110,000 - $150,000 + up to 10% annual bonus

Location: Sylmar, CA

Type: Permanent | On-site
