Senior Mechanical Engineer

Maxwell Bond; New York (NY); On-site; USD 120,000 - 300,000; Full time

Job summary

Maxwell Bond is seeking a Senior Mechanical Engineer to own the mechanical design and development of next-generation humanoid manipulation hardware, including robotic arms, actuated joints, transmissions, and end effectors, from concept through production. The role requires hands-on experience shipping electromechanical hardware, strong CAD skills (SolidWorks/Creo/NX/Onshape), and GD&T with FEA.

You will prototype rapidly, lead testing, and collaborate with controls, electrical, and firmware

Qualifications

• 5+ years designing and shipping electromechanical hardware
• Experience with robotic manipulators or similar systems
• CAD proficiency in industry tools
• Knowledge of GD&T, tolerance stacks, machine design and structural analysis

Responsibilities

• Own mechanical design of robotic arms, joints, actuators, transmissions and end effectors
• Design mechanisms optimized for torque density, backdrivability, weight, stiffness and cost
• Integrate motors, gearing, bearings, sensors, and structures into compact assemblies
• Apply GD&T, tolerance analysis, machine design, and FEA/structural analysis
• Rapidly prototype using 3D printing, CNC, and other fabrication methods
• Lead testing, characterization, durability testing and failure analysis
• Drive DFM/DFA and coordinate with suppliers to move designs into production
• Collaborate with controls, electrical, and firmware teams

Job description

Senior Mechanical Engineer - Humanoid Robotic Manipulation

What's In It For You?

• Competitive compensation up to $300k + equity
• Own the mechanical design and technical game plan for next-generation Humanoid manipulation hardware
• High level of technical ownership and autonomy, with the opportunity to shape architecture & engineering standards
• Work on complex manipulation problems involving actuators, joints, transmissions, end effectors, and robotic arms
• Work alongside exceptional engineers across controls, electrical, firmware, and robotics

About the Role

I'm working with a well-funded robotics company developing advanced robotic systems for industrial and manufacturing environments. They're looking for a Senior Mechanical Engineer to design and develop robotic arms, actuated joints, transmissions, structures, and end effectors from concept through production.

This is a hands-on IC role for someone who has shipped real robotic or high-performance electromechanical hardware and wants significant ownership over the technical direction.

What You'll Do As A Senior Mechanical Engineer:

• Own mechanical design of robotic arms, joints, actuators, transmissions, and end effectors.
• Design mechanisms optimised for torque density, backdrivability, weight, stiffness, durability, and cost.
• Integrate motors, gearing, bearings, sensors, and structures into compact assemblies.
• Apply GD&T, tolerance analysis, machine design, and FEA/structural analysis.
• Rapidly prototype using 3D printing, CNC, and other fabrication methods.
• Lead testing, characterization, durability testing, and failure analysis.
• Drive DFM/DFA and work with suppliers/CMs to move designs into production.
• Collaborate closely with controls, electrical, and firmware teams.

What We're Looking For

• 5+ years designing and shipping electromechanical hardware as a Mechanical/Senior Mechanical Engineer.
• Hands-on experience with robotic manipulators, actuated joints, robotic arms, cobots, legged robots, aerospace mechanisms, or similar systems.
• Strong experience with actuators, motors, gearing/transmissions, bearings, and mechanisms.
• Expert CAD skills in SolidWorks, Creo, NX, Onshape, or similar.
• Strong understanding of GD&T, tolerance stacks, machine design, materials, and structural analysis.
• Proven ability to take hardware from concept → prototype → validated production.

Nice to Have

• Dexterous hands, grippers, or end-effectors
• Humanoid or legged robotics
• FEA, topology optimisation, or lightweighting
• Controls/dynamics knowledge
• Prototype-to-volume manufacturing experience
