Principal Simulation Systems Engineer

Build the Simulation Backbone That Predicts, Explains, and Improves Manufacturing

Hybrid/Remote · 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 performance — making First Part Right manufacturing a reality at scale.

This is not a simulation for visualization.

This is not academic modeling disconnected from production.

This is the engineering of high-value simulation systems that help interpret machine behavior, predict process outcomes, accelerate learning, and improve correction intelligence in real manufacturing environments.

Now, we are expanding our core technical team with a principal-level simulation engineer who can design, build, and deploy advanced simulation environments from first principles.

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

The Mission

Design and implement the simulation systems that model machine behavior, sensing interaction, geometric variation, process dynamics, and manufacturing outcomes — enabling 4MP to predict, validate, and improve autonomous correction strategies.

What You Will Build

• Simulation environments for CNC process behavior and machine response
• Virtual models of machining error sources and geometric deviation
• Toolpath and machine kinematic simulation frameworks
