Genesis10 is currently seeking a Senior CNC Programmer / Engineer for an onsite position with a Global Manufacturing Company located in Sylmar, CA. This is a direct hire opportunity. Salary Range: $110,000 - $140,000 based on experience and qualifications

Job Overview

This role is part of a dynamic engineering team focused on CNC programming, process planning, tooling, and continuous improvement for multi-axis CNC machining operations. The ideal candidate will be a technically curious engineer who evaluates emerging technologies and applies innovative approaches to define and optimize machining strategies for the efficient, high-quality, and cost-effective production of precision plastic transparencies.

Primary Responsibilities

• Develop, modify, and optimize CNC programs for multi-axis (3, 4, 5-axis) milling machines to support manufacturing of plastic transparencies, composites, and aerospace tooling components
• Utilize CAM software such as Mastercam, NX, CATIA, or similar
• Design and qualify cutting tools, fixturing, and work holding for aerospace and precision plastic CNC machining applications
• Establish and continuously refine machining parameters, coolant/lubrication delivery, and machining strategies to drive stable, repeatable production while meeting requirements for tool life, dimensional accuracy, surface finish, and AS9100 compliance
• Apply CNC simulation and verification tools (e.g., VERICUT) for digital twin validation, collision avoidance, and process reliability
• Interpret and create technical drawings, GD&T, and 3D CAD models to produce accurate and compliant toolpaths
• Evaluate and implement emerging machining technologies, tooling solutions, and industry best practices by actively researching suppliers, attending trade shows, and benchmarking new techniques
• Evaluate, qualify, and recommend new CNC machinery and equipment, supporting strategic capital investment decisions to enhance manufacturing capability and process reliability

Required:

• Due to the nature of work performed, candidates must be U.S. Citizens. No exceptions can be made for this requirement.
• 7 years of progressive experience in CNC programming and machining in aerospace, defense, and high-precision industries, with experience in plastics machining
• Proficient in 5-axis/multi-axis CNC machining required
• CNC strategies: tool/cutter, coolant, feeds/speed selection and optimization
• CNC simulation and verification tools (EG Vericut)

Preferred:

• Bachelor's Degree in Manufacturing or Mechanical Engineering not required but preferred
• Experience on Zimmermann, CMS, Makino, DMG MORI, Mazak, Okuma, or Haas platforms, and skilled in Siemens SINUMERIK, Fanuc, and Mazatrol controls preferred
• Experienced in CAD/CAM software (Siemens NX, CATIA, Mastercam) and G-/M-code programming
• Knowledge of GD&T (ASME Y14.5) and blueprint interpretation, applied to aerospace and high-precision manufacturing tolerances
