Sr. Mechatronics Engineer - Actuation & Drivetrain
Core
Own the complete actuation and drivetrain system for a counter-drone machine, converting electrical signals into precise mechanical motion for azimuth, elevation, and auxiliary mechanisms.
Role type
Senior Mechatronics Engineer (Actuation & Drivetrain)
Builds
Counter-drone interception systems (EDDA) for vehicles, bases, and soldier packs.
Domain
Defense / Robotics / Motion Control
Required skills
BLDC/PMSM servo system selection and tuning, gearbox design (planetary, strain-wave, cycloidal), drivetrain mechanical design, actuator characterization and testing, supply chain management, C/C++ or Python for drive configuration and test automation, CAD (SolidWorks)
Preferred skills
MIL-STD-810 harsh environment qualification, weapon-mounted motion systems, custom motor design (FEA), solenoid design, structural dynamics, advanced control algorithms, drive ecosystems (CAN, EtherCAT, ROS 2)
Technologies
BLDC, PMSM, frameless torque motors, planetary gearboxes, strain-wave gearboxes, cycloidal drives, worm drives, BLDC drives, ODrive, moteus, Elmo, Copley, Kollmorgen, SolidWorks, Python, MATLAB, C/C++, Ansys Maxwell, JMAG, FEMM
Responsibilities
Size and select motors, gear ratios, and drives based on torque, speed, and inertia requirements; design mechanical drivetrain paths including bearings, shafts, and couplings; build test rigs and run characterization tests (torque, efficiency, thermal, backlash); tune current, velocity, and position control loops; engineer for abuse (shock, vibration, dust, water, temperature); manage vendor qualification and cost-down; bridge mechanical, electrical, and firmware teams; document procedures and acceptance tests.
Seniority
