Principal CNC​/CAM Engineer - Autonomous Machining Systems

Bridge Digital Intelligence with Real-World Machining

Hybrid/On-site
· HQ Allentown, PA
· Seed Stage

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

We are creating systems that enable CNC machines to self-diagnose, self-correct, and continuously improve their geometric and process accuracy — making First Part Right manufacturing a reality at scale.

This is not academic research. This is not theoretical modeling.

This is the execution of autonomous machining systems in real production environments, working with real parts, real tools, and real constraints.

Now, we are expanding our core technical team with a principal-level CNC and CAM expert who deeply understands how CAM software thinks and how machines behave on the shop floor.

We are not looking for followers. We are looking for builders who thrive on frontier problems and take ownership of complex manufacturing systems.

The Mission

Design, validate, and integrate CNC programming and CAM strategies into 4MP’s autonomous correction platform, ensuring that software intelligence translates into practical, reliable machining outcomes.

What You Will Build

· CAM-to-CNC correction and optimization workflows

· Post-processor-aware correction strategies

· Adaptive toolpath modification systems

· Closed-loop feedback integration with CAM environments

· Best-practice machining strategies for autonomous correction

· Toolpath validation and verification pipelines

· Process-aware Digital Twin representations

· Standardized programming frameworks across machines
