> Senior Mechatronics Engineer designs and integrates precision robotic hardware systems for manufacturing custom prosthetics, including actuators, sensors, and motion control. Requires 5+ years experience in mechatronics/robotics, BS/MS in relevant field, and expertise in Solidworks, kinematics, and prototyping.

## Job Description

## What You’ll Do

- **System Architecture & Design**: Architect and integrate complex robotic hardware systems, including precision actuators, sensors, and electromechanical subsystems, ensuring they meet the micron-level reliability required for manufacturing custom-made prosthetics.
- **Special Purpose Machine Design Expertise**: Apply deep technical knowledge of both additive (3D printing) and subtractive (milling, grinding, polishing) processes to design versatile, high-precision manufacturing platforms.
- **High-Fidelity Prototyping**: Lead the rapid prototyping of components and conduct rigorous structural/thermal analyses. Validate designs through intensive performance testing and failure-mode analysis (FMEA).
- **Control & Communication**: Implement and refine motor control logic, sensor fusion, and real-time feedback loops. Define the communication protocols (e.g., EtherCAT, CANopen) to enable robust, real-time robotic operation.
- **Cross-Functional Integration**: Act as the primary technical interface between mechanical, electrical, firmware, and software teams to ensure seamless system integration and optimization of system dynamics.

## What We’re Looking For

- **Experience**: 5+ years of machine-building experience, specifically in hardware, mechatronics, or robotics engineering with a focus on system-level architecture for production systems.
- **Education**: B.S./M.S. or Ph.D. in Mechatronics, Mechanical, Electrical, or Robotics Engineering.
- **Technical Mastery**:
  - Expert-level proficiency with **Solidworks** or similar platforms and a deep understanding of varied fabrication and manufacturing processes.
  - Profound knowledge of robotic kinematics/dynamics, motor controllers, and simulation tools.
  - Hands-on experience with sensor integration, embedded systems, and industrial design execution.
- Soft Skills: Exceptional analytical and problem-solving skills, with the ability to mentor junior engineers and manage multiple projects in a high-velocity high growth environment.
- Ability to self-direct, self-managing issues to closure involving all necessary teams, and adapt quickly to program changes.
- Willingness to travel to suppliers, manufacturing, and testing facilities as required (~20% travel).

## Bonus Points For

- Experience working as a System or Mechanical Engineer for an Automation System Integrator or OEM, with a track record of delivering turnkey automated solutions.
- Advanced Motion Control: Knowledge of waveform tuning, custom PLC programming (**Beckhoff/TwinCAT**), or experience with high-performance motion controllers (ACS, Elmo, Others).
- Experience with laser interferometry, high-resolution optical encoders, and sub-micron calibration techniques for milling and printing paths.
- Expertise in integrating Automated Optical Inspection (AOI) and 3D vision systems into robotic workflows for real-time quality feedback.
- Advanced capability in FEA/CFD for thermal and vibration analysis of high-speed robotic linkages and spindles.
- Experience with the design or qualification of custom brushless motors, linear actuators, or robotic end-effectors.
- Robotic Safety: Knowledge of ISO 10218 or ISO 13482 standards for robotic system safety and collaborative operation.
