Manufacturing Engineer – Advanced Composite Machining

Location: Torrance, California, United States

Company

hirify.global develops and delivers advanced defense systems, with an early-stage focus on rapid execution and production capability.

What you will do

• Develop, simulate, prove out, and optimize complex 5-axis CNC machining operations.
• Create and maintain CAM programs, post-processed code, setup sheets, tooling lists, and machining documentation using Siemens NX CAM and/or Mastercam.
• Select and optimize diamond, PCD, carbide, and other specialized cutting tools for carbon-carbon, phenolic, C/SiC, and related composite materials.
• Develop workholding, fixturing, support, datum, dust-extraction, and material-handling strategies for composite machining.
• Run tooling trials and analyze tool life, surface finish, dimensional accuracy, cycle time, cost per part, scrap, and process capability.
• Collaborate with design, quality, and manufacturing engineering to transition R&D hardware into validated, repeatable production processes.

Requirements

• Extensive hands-on experience with 5-axis CNC milling and complex machining operations.
• Demonstrated CAM programming experience with Siemens NX CAM and/or Mastercam.
• Direct experience machining advanced composites, preferably carbon-carbon, phenolic, or carbon-silicon carbide.
• Strong knowledge of cutting tool selection, cutting parameters, toolpath strategy, workholding, fixturing, setup, prove-out, and process validation.
• Ability to interpret engineering drawings, GD&T, CAD models, and dimensional inspection results.
• Commitment to safe machining practices, including controls for composite dust and material-specific hazards.

Nice to have

• Experience with aerospace, defense, propulsion, thermal protection, or high-performance composite components.
• Experience with tool-life studies, tooling cost models, standardized cutting-parameter libraries, CNC post-processors, simulation, and collision avoidance.
• Experience taking parts from R&D prototypes through process qualification and production release.

Culture & Benefits

• Hands-on work in an early-stage environment with significant ownership.
• Close collaboration across engineering, quality, and manufacturing teams.
• Generous benefits package.
• Work involving advanced defense systems and potentially classified or export-controlled information.
