• Solid skills in SolidWorks, 3D CAD (OnShape preferred), GD&T (ASME Y14.5), and documentation
• Experienced with P&ID, pneumatic and hydraulic circuits design including driving loads, sensing and actuation of manipulators, solenoid valves, regulators etc.
• Experience with system dynamics, simulation, and vibration analysis is a big plus
• Demonstrated experience both designing electro-mechanical industrial systems from concept design through product release/shipment at scale
• Bonus: MATLab or Python experience, industrial tooling design, BOM structuring

Why You’ll Love It:

• Design from scratch, prototype fast, and see your systems come to life
• Make decisions with impact in a startup that values autonomy and execution
