Responsibilities
Own the full lifecycle of mechatronics systems: requirements definition, architecture, design, prototyping, testing, release, and iteration
Design precision mechanisms, paper-handling components, motion assemblies, and supporting structures
Select and integrate actuators, sensors, linear motion systems, and industrial components
Design wiring harnesses, cable routing, sensor interfaces, and panel layouts
Develop control architectures including PLC logic, embedded firmware, state machines, and motion profiles
Apply principles of control theory, system modeling, and dynamics to achieve smooth, reliable motion
Collaborate with electrical engineers, machinists, software engineers, and operations teams to bring designs into production
Lead debugging and root-cause analysis efforts for mechanical, electrical, or firmware issues
Support manufacturing through documentation, build procedures, BOMs, testing protocols, and quality control
Drive continuous improvements in throughput, reliability, uptime, and ease of maintenance
