Westmag is committed to building and scaling in the U.S. to serve the global market. For more information, visit westmag.com.\nAbout the role\nAs a Mechanical Engineer at Westmag, you will lead the mechanical design of the drone motors and robotic actuators at the heart of our products. You will own the rotating machinery, bearing systems, gears, and transmissions that turn electromagnetic torque into reliable mechanical output, balancing performance, weight, and cost. Working at the intersection of design and production, you will ensure every part you draw can be built at scale, and your work will directly shape Westmag's ability to ship millions of motors and actuators from U.S. factories.\nWhat you'll own\nDesign and optimize the mechanical architecture of motors and actuators, including shafts, housings, bearing systems, gears, and transmissions.\n\nPerform structural, tolerance stack-up, fatigue, and bearing support analyses to ensure durability and precision across the product's operating envelope.\n\nDrive DFM/A from the earliest concepts, engineering parts for high-volume production where manufacturability is as critical as performance.\n\nExplore high volume manufacturing methods such as stamping and casting working with suppliers to ensure designs are producible, repeatable, and cost-effective at scale.\n\nCreate detailed CAD models, GD&T-based drawings, and design documentation for components and assemblies.\n\nWork cross-functionally with Motor Design, Manufacturing, Quality, and Field Applications Engineers to ensure design feasibility, manufacturability, and customer requirements are met.\n\nSupport prototyping, testing, and validation of new designs, and drive continuous improvement across the product line.\n\nRequired qualifications\nBachelor's degree in Mechanical Engineering or a related technical field.\n\n3+ years of experience in mechanical design, preferably in drone, robotics, automotive, aerospace, or high-volume electromechanical products.\n\nIndustry experience with rotating machinery, including bearings, gears, or transmissions.\n\nHands-on knowledge of metal manufacturing methods such as milling, turning, stamping, and casting.\n\nDemonstrated experience with DFM/A designing high-volume products.\n\nProficiency with CAD tools for mechanical design (e.g., SolidWorks, Onshape), including GD&T.\n\nExcellent problem-solving, analytical, and communication skills, with the ability to collaborate across multidisciplinary teams.\n\nAuthorized to work in the United States.\n\nPreferred qualifications\nFamiliarity with electromagnetism and electric motor fundamentals.\n\nExperience with rotor dynamics, thermal analysis, or NVH (noise, vibration, and harshness).\n\nKnowledge of manufacturing processes for motor and actuator components and assemblies.\n\nHands-on experience with prototype testing, validation, and design iteration in a production environment.","description_format":"text","description_chars":3078,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Drones & UAVs","Motors, Drives & Motion Control"],"lifecycle":[{"event":"open","at":"2026-10-01T23:12:26Z"}],"visa":[],"liveness":{"score":55,"band":"ok","label":"Likely open","p_open":1,"p_active":0.702,"p_room":0.788,"age_days":15,"expected_fill_days":18,"reasons":["conf:0","velocity","win:late"],"computed_at":"2026-10-04T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/westmag-mechanical-engineer","json_url":"https://alion.io/job/westmag-mechanical-engineer.json","meta":{"generated_at":"2026-10-05T01:38:36Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2201,"day_limit":5000,"remaining_today":2799,"minute_limit":60,"resets_at":"2026-10-06T00:00:00Z"}}}
