Mechanical Design Engineer

Mechanical Design Engineer (Robotics)San Francisco, CA (onsite)Up to $250K + EquityNo Visas transfersMy client builds general intelligent robots for highly dexterous industrial tasks — starting with data centre operations like GPU repairs, precision cabling, and SSD replacements for hyperscalers like Meta, Google, Oracle, and Microsoft.Hardware is designed and manufactured in-house, so you'll iterate fast with a tight-knit team that values ownership and autonomy. They're solving genuinely hard robotics problems that actually ship to production environments.We are looking for a Mechanical Design Engineer with 2-8 years of experience to own mechanical subsystems from concept through working prototype on autonomous robotic systems deployed in real data centre environments. You'll join a tight-knit, in-house hardware team where iteration, fabrication, and execution all happen under one roof.This is a hands-on role for someone who thrives at the intersection of CAD and the shop floor — designing, building, breaking, and iterating on real hardware that makes robots stop being demos and start being infrastructure. If you have a strong portfolio of complete systems taken from concept to physical prototype and love moving fast on hard problems, this is your opportunity.What will you be doing?Own mechanical subsystem design from first sketch through prototype and iteration, making decisions on materials, tolerances, and manufacturing methodsDesign parts and assemblies in CAD, supported by hand calculations and FEA, optimized for rapid prototyping methods including 3D printing and CNC machiningBuild prototypes yourself using 3D printers, shop tools, and CNC equipment — turning designs into physical hardware quicklyIntegrate mechanical designs with motors, sensors, electronics, and actuators on robotic arms and mobile basesCollaborate closely with electrical, software, and robotics teams to bring complete autonomous systems together for production deploymentRequirementsBuilt physical prototypes from concept to working hardware (e. g. , robotics, aerospace, consumer hardware)Proficient in CAD (SolidWorks, Fusion 360, or equivalent)2 - 5 years of experience in mechanical design engineering for robotic or hardware systemsExperience at a hardware startup or hands- on engineering team (FSAE, robotics club, etc. )BS in Mechanical Engineering or related fieldHands- on fabrication: 3D printing, CNC machining, shop toolsTakes ownership of subsystems end- to- end without waiting for directionWorked on mechatronic systems integrating motors, sensors, or actuatorsExperience with FEA or topology optimizationMust work on- site in San Francisco, CA full- timeNo visa sponsorship; must be authorized to work in the US
