Principal CNC Machining & CAM Optimization Engineer

About the job

Bridge Software Intelligence with Real-World Machining Execution


Hybrid / On-site • Allentown, PA • Relocation Support Available • Seed Stage

About 4MP


At 4MP, we are building a new foundation for precision manufacturing.


We are creating systems that enable CNC machines to self-diagnose, self-correct, and continuously improve machining accuracy and process performance - making First Part Right manufacturing a reality.

This is not academic research.


This is not theoretical modeling.

This is the execution of intelligent manufacturing systems on real machines, real parts, and real production constraints.

We are now looking for a principal-level expert in machining and CAM who can ensure that software intelligence translates into real machining performance.

The Mission


Own the machining-side definition and real-world validation of the 4MP platform - ensuring that software-driven corrections, optimizations, and recommendations translate into measurable improvements in accuracy, stability, repeatability, and production performance.


You will serve as the critical bridge between software development and machining reality, creating a continuous feedback loop between algorithmic decisions and shop-floor execution.

What You Will Do
• Work closely with the software development team to define how 4MP logic interacts with machining processes, CAM strategies, and CNC programs
• Evaluate and validate software-generated corrections in real machining environments
• Provide continuous feedback to improve how the platform translates digital intelligence into machining performance
• Collaborate with CNC operators, machinists, and process engineers to test and refine software-driven recommendations
• Run or support real-world machining trials, including toolpath changes, machine settings, and process adjustments
• Ideally, independently set up and execute selected CNC tests to accelerate validation cycles
• Identify where software recommendations are manufacturable, where they need refinement, and where they create measurable value
• Contribute to best practices in CNC programming, CAM strategy, and machining optimization within the platform
• Help standardize machining approaches across different machines, parts, and production environments

Role Nature: Principal-Level Bridge Between Software & Machining


This is a hands-on, high-impact role combining deep machining expertise with system-level thinking.


You will not only help define how machining intelligence is built into the platform - you will prove that it works in reality.


Your responsibility is to ensure that what is computed digitally can be executed physically, reliably, and repeatedly.

Who You Are
• Deep expert in machining, CNC programming, and CAM strategy
• Strong understanding of how toolpaths, machine behavior, setups, and cutting conditions interact
• Comfortable working closely with software engineers and translating machining knowledge into system logic
• Highly practical - able to judge whether something will actually work on a machine
• Experienced working with CNC operators and shop-floor teams
• Ideally capable of independently running CNC machines and validating outcomes
• Motivated by solving real-world, high-impact manufacturing problems
• Thrives in fast-moving, ambiguous, early-stage environments

Technical Requirements (Must-Have)
• 10+ years of experience in CNC machining, CAM programming, or manufacturing process optimization
• Expert-level knowledge of CNC programming and toolpath strategy
• Deep experience with major CAM platforms (NX CAM, Mastercam, PowerMill, Fusion 360, HyperMill, etc.)
• Strong understanding of feeds & speeds, tool selection, engagement strategies, setups, and machining dynamics
• Proven ability to optimize machining processes for accuracy, stability, repeatability, and cycle time
• Experience troubleshooting machining issues across programming, setup, and process execution
• Strong understanding of high-precision manufacturing environments
• Ability to collaborate effectively with software, data, and engineering teams

Strongly Preferred
• Hands-on experience running and testing CNC machines
• Experience in aerospace, automotive, medical, or other high-precision industries
• Experience in high-mix / low-volume production environments
• Multi-axis machining experience (especially 5-axis)
• Understanding of post-processors, machine kinematics, and controller behavior
• Experience with probing, in-process inspection, or closed-loop manufacturing
• Strong intuition for real-world manufacturability vs theoretical optimization

Experience & Education

Required:
• 10+ years of relevant industry experience
• Demonstrated success improving machining processes in real production environments
• Bachelor's degree in Mechanical Engineering, Manufacturing Engineering, or equivalent practical experience


Preferred:
• Advanced degree in a related field
• Experience in advanced manufacturing, automation, or digital manufacturing systems

Location


This role is based in Allentown, Pennsylvania, working closely with physical machines and validation environments.


Relocation support is available for exceptional candidates.

Why This Role Matters


This role ensures that 4MP is not just intelligent - but effective.


You will directly influence whether software decisions result in:
• Better parts
• More stable processes
• Faster setups
• Higher yield


You are the person who closes the loop between code and cutting metal .

Why Join Now


We are at the stage where intelligent machining moves from concept to execution.


Joining now means:
• Defining how software interacts with real manufacturing
• Building something that has never been done at this level
• Working at the intersection of AI, physics, and machining
• Having a direct impact on how the next generation of factories operates
