Manufacturing Engineer, CNC

Mach Industries is seeking a Manufacturing Engineer, CNC to own the manufacturing strategy and producibility of complex CNC-machined hardware from development through production.

This role sits at the intersection of design engineering, CAM programming, machining, quality, and production . You will be responsible for determining how parts should be manufactured, identifying the major technical risks in the machining process, and driving the larger process changes required to improve producibility, quality, cost, and scalability.

This is not primarily a CAM programming or machine-operating role. Dedicated CAM programmers will develop CNC programs, and machinists will execute setups and run parts. The Manufacturing Engineer is responsible for providing the technical direction that connects those functions—defining the manufacturing approach, challenging existing methods, resolving cross-functional problems, and ensuring the complete process is capable of meeting program requirements.

You will work at both the part level and manufacturing-system level , diving deeply into CNC technology, tooling, workholding, probing, machine capability, automation, process monitoring, and inspection feedback to continuously improve how Mach manufactures hardware.

• ◆Own CNC manufacturing strategy and producibility for assigned hardware and manufacturing projects.
• ◆Partner with design engineering early in the product lifecycle to influence geometry, tolerances, material selection, datum structures, and other design decisions that affect manufacturability.
• ◆Define the overall machining approach, including operation breakdown, machine platform, setup strategy, datum strategy, workholding concept, tooling approach, inspection strategy, and process-control requirements.
• ◆Provide technical direction to CAM programmers while allowing programmers to own the detailed creation and maintenance of CNC programs.
• ◆Work with machinists during prove-out and production to understand process behavior, identify failure modes, and determine required engineering changes.
• ◆Lead larger CNC process improvements involving changes to machining strategy, tooling, workholding, probing, sequencing, machine utilization, or process architecture.
• ◆Drive first-article and process-development activities from initial manufacturing strategy through a stable, repeatable production process.
• ◆Identify and resolve manufacturing risks related to chatter, distortion, tool wear, thermal behavior, dimensional drift, surface finish, workholding, machine capability, and process variation.
• ◆Use inspection results, machine data, spindle load, probing results, tool-life data, and operator feedback to understand process performance and prioritize improvements.
• ◆Develop and validate strategies for in-process probing, tool monitoring, automated compensation, inspection feedback, and other forms of closed-loop process control.
• ◆Evaluate new CNC technologies, machines, cutting tools, workholding systems, monitoring technologies, software, and automation capabilities.
• ◆Lead technical investigations and manufacturing-development projects that improve CNC capability across the organization.
• ◆Establish manufacturing standards and engineering best practices that can be reused across parts, programs, machines, and facilities.
• ◆Develop mature manufacturing processes that can transition from Huntington Beach development into repeatable production with clearly defined technical

and process controls.
