About the company

Our client is a robotics company.

The role

Raydar is recruiting for this role on behalf of our client. Lead the mechanical architecture of compact motion hardware, turning machine performance needs into a buildable design. The work balances competing physical limits such as output force, weight, energy use and heat, with hands-on prototyping and testing.

What you'll do

- Turn robot load and duty-cycle requirements into specific actuator targets for torque, speed, stiffness, life, packaging and temperature.

- Weigh motor layout, gearing, bearings, cooling, sensing and drive limits, using test data to settle competing requirements.

- Set the boundaries between mechanical hardware, power electronics and embedded code, covering electrical ceilings, sensor locations and how the unit responds to faults.

- Build prototypes and debug hardware on the bench, owning CAD and analysis reviews and key technical decisions.

- Plan characterization work with motor, controls and test engineers, and match measured results against models.

- Lead design reviews, supplier choices and manufacturability work through to production release.

Requirements

What we're looking for

- Experience in in-house mechanical design.

- Track record of taking a motion component or powered mechanism from design into shipped equipment.

- Prior work on dense, high-output motion hardware with active cooling.

- Strong depth in mechanical or mechatronic design.

- Solid grasp of how electric machines, gearing, heat, sensing and power electronics constrain one another.

- Practical record of building test units, verifying them, working with vendors and handing designs off to manufacturing.

- Ability to work on-site in the role's location.

Bonus points

- Experience at leading robotics or automotive companies.

- Background in machine joint modules, factory drive equipment, electric vehicle propulsion or aircraft motion systems.
