Mechanical Engineer – Drone Motors & Actuators

Western Magnetics; South San Francisco (CA); On-site; USD 110,000 - 170,000; Full time

Job summary

Westmag in the United States is seeking a Mechanical Engineer to lead the mechanical design of drone motors and robotic actuators. You will own rotating machinery, bearings, gears, and transmissions, balancing performance, weight, and cost while ensuring parts can be built at scale.

You will collaborate with Cross-functional teams to ensure feasibility, manufacturability, and customer requirements, and support prototyping, testing, and validation across the product line.

Qualifications

• Bachelor's degree in Mechanical Engineering or related field.
• 3+ years in mechanical design, preferably in drone, robotics, automotive, aerospace, or high-volume electromechanical products.
• Industry experience with rotating machinery, including bearings, gears, or transmissions.
• Hands-on knowledge of metal manufacturing methods such as milling, turning, stamping, and casting.
• Demonstrated experience with DFM/A designing high-volume products.
• Proficiency with CAD tools for mechanical design (e.g., SolidWorks, Onshape), including GD&T.

Responsibilities

• Design and optimize the mechanical architecture of motors and actuators, including shafts, housings, bearing systems, gears, and transmissions.
• Perform structural, tolerance stack-up, fatigue, and bearing support analyses to ensure durability and precision across the product's operating envelope.
• Drive DFM/A from the earliest concepts, engineering parts for high-volume production where manufacturability is as critical as performance.
• Explore high volume manufacturing methods such as stamping and casting working with suppliers to ensure designs are producible, repeatable, and cost-effective at scale.
• Create detailed CAD models, GD&T-based drawings, and design documentation for components and assemblies.
• Work cross-functionally with Motor Design, Manufacturing, Quality, and Field Applications Engineers to ensure design feasibility, manufacturability, and customer requirements are met.
• Support prototyping, testing, and validation of new designs, and drive continuous improvement across the product line.
