# Simulation and Digital Twin Lead

Simulation and Digital Twin Lead GRAM, San Francisco Bay Area About the company GRAM Corporation scales skilled labor for the physical economy. We design, manufacture and operate insectoids, general-purpose machines not built in our image. They work in large populations on the critical infrastructure nations depend on. The electric grid comes first. Our research is in how those populations coordinate and keep themselves running. The goal is Self-Replication (SR), the point where a population of machines delivers more labor than it takes to build and run. The role You will own the simulation stack and tooling used by the whole engineering team, and build a high-fidelity digital twin of the robot that is validated against real hardware. The Controls, Autonomy and Systems Integration teams will rely on it to develop and test before anything runs on the robot. This is a hands-on role: you will choose the tools, build the models yourself and prove that simulation matches the machine. You start as an individual contributor, with a path to build and lead a team as the company grows. What you will do Own the simulation stack and tooling used by the whole engineering team, including the cho
