Mechanical Engineer

Alexander Chapman; California (MO); On-site; USD 120,000 - 180,000; Full time

Job summary

Alexander Chapman is seeking an experienced Mechanical Engineer to design and ship electromechanical hardware for humanoid robotic systems. You will own the mechanical architecture from concept to production, ensuring robustness for real factory environments.

The role requires deep expertise in mechanism and actuator design, machine design, GD&T, tolerance analysis, and proficiency with major CAD tools such as SolidWorks, Creo, NX, or Onshape.

Qualifications

• 5+ years of hands-on electromechanical hardware design.
• Experience with robotic manipulators or precision motion systems.
• Strong CAD and manufacturing know-how (DFM/DFA).
• Knowledge of GD&T and tolerance analysis.

Responsibilities

• Design robotic arms, joints, actuators, transmissions, structures, and end effectors end-to-end.
• Optimize mechanisms for torque density, backdrivability, weight, stiffness, durability, and cost.
• Integrate motors, gearing, bearings, sensors, and structures into compact, manufacturable assemblies.
• Rapidly prototype with 3D printing and CNC, then transition designs into repeatable production hardware.
• Lead testing, durability analysis, failure investigation, and DFM/DFA alongside suppliers and manufacturing partners.

I'm partnering with an ambitious robotics company building and deploying humanoid robots in real factory environments. They're looking for a Mechanical Engineer to design the manipulation hardware that makes these robots genuinely useful, owning critical components from early concepts through production and deployment.

In this role, you'll:

• Design robotic arms, joints, actuators, transmissions, structures, and end effectors end-to-end
• Optimize mechanisms for torque density, backdrivability, weight, stiffness, durability, and cost
• Integrate motors, gearing, bearings, sensors, and structures into compact, manufacturable assemblies
• Rapidly prototype with 3D printing and CNC, then transition designs into repeatable production hardware
• Lead testing, durability analysis, failure investigation, and DFM/DFA alongside suppliers and manufacturing partners

They're looking for an engineer with 5+ years of hands-on experience designing and shipping electromechanical hardware, ideally involving robotic manipulators, actuated joints, humanoids, cobots, legged robots, or precision motion systems. Deep expertise in mechanism and actuator design, machine design, GD&T, tolerance analysis, and a major CAD platform such as SolidWorks, Creo, NX, or Onshape is essential. Experience with dexterous hands, FEA, lightweighting, sensors, or whole-body robotics is a strong plus.

This is an on-site opportunity in New York City with significant ownership over the mechanical architecture and the chance to build manipulation hardware designed to operate reliably on real factory floors.
