Mechanical Engineer, Actuator Design

About the company Our client is a robotics company. The role Raydar is recruiting for this role on behalf of our client. Lead the mechanical architecture of compact motion hardware, turning machine performance needs into a buildable design. The work balances competing physical limits such as output force, weight, energy use and heat, with hands-on prototyping and testing. What you'll do - Turn robot load and duty-cycle requirements into specific actuator targets for torque, speed, stiffness, life, packaging and temperature. - Weigh motor layout, gearing, bearings, cooling, sensing and drive limits, using test data to settle competing requirements. - Set the boundaries between mechanical hardware, power electronics and embedded code, covering electrical ceilings, sensor locations and how the unit responds to faults. - Build prototypes and debug hardware on the bench, owning CAD and analysis reviews and key technical decisions. - Plan characterization work with motor, controls and test engineers, and match measured results against models. - Lead design reviews, supplier choices and manufacturability work through to production release. Requirements What we're looking for - Experience in in-house mechanical design. - Track record of taking a motion component or powered mechanism from design into shipped equipment. - Prior work on dense, high-output motion hardware with active cooling. - Strong depth in mechanical or mechatronic design. - Solid grasp of how electric machines, gearing, heat, sensing and power electronics constrain one another. - Practical record of building test units, verifying them, working with vendors and handing designs off to manufacturing. - Ability to work on-site in the role's location. Bonus points - Experience at leading robotics or automotive companies. - Background in machine joint modules, factory drive equipment, electric vehicle propulsion or aircraft motion systems. Benefits Compensation and benefits - Base salary: USD 180,000 to 280,000 per year - Equity Location and work model - Fremont, California, United States - On-site - Full-time
