Job description: **About**\ Foundation Industries is building the supply base for frontier hardware companies: We CNC machine critical components and have built a manufacturing platform that connects every step of the process into one continuously improving, software-defined system. We're backed by Y Combinator and other awesome investors and have shipped parts to customers like Skydio, Westmag, and Askari Defense. \ **Role Description**\ We're hiring a Mechanical Engineer to work on some of the hardest problems in high-mix manufacturing. One of the core constructs of our culture is to get hands dirty first and engineer solutions second. We require no proficiency in CNC machining, but rather a capacity to learn it at lightning speed. \ You'll work directly with the founding team and partner closely with our software team. What you identify on the factory floor will directly shape the software and hardware automations you build in the future. **\ Near Term** * Learn the fundamentals of CNC machining * Run parts end-to-end: CAM programming, setup, and production * Surface friction in our current process: programming workflows, tool management, materials, inspection, etc. Work with our software team to turn those frictions into platform features. **Longer-term** * Build workflow automations for CAM generation * Automate DFM feedback on uploaded customer CAD files * Contribute to the onboarding curriculum and facility playbooks that turn Foundation's tribal knowledge into systems **Who you are** * A degree in mechanical engineering or equivalent hands-on background * Proficient in CAD and eager to learn CAM and CNC from the ground up * Ready to grind on the facility floor **Comp** * $100k annual salary * Equity grant (early-stage, meaningful)
