Mechanical Design & Motor Control Engineer at Criterion Tech · Lucknow

• Design mechanical assemblies, linkages, and mechanisms in CAD, including multi-DOF arm structures, gear trains, and pulley/belt drive systems
• Select, size, and tune motors and drives (stepper, servo, or BLDC) for the intended mechanism
• Develop and debug embedded firmware for motor control on microcontrollers
• Program and integrate PLC-based control logic for industrial-grade systems
• Configure and troubleshoot RS485/CAN/Modbus communication between controllers and drives
• Perform kinematic calculations (forward/inverse) for multi-axis mechanisms
• Read and debug PCB-level driver boards; collaborate with electronics teams on interface design
• Apply GD&T and tolerancing appropriate to the chosen manufacturing method (machining, 3D printing, or sheet metal)
• Make sound design-for-manufacture (DFM) decisions based on realistic fabrication capability
• Design end-effectors, grippers, and mechanism enclosures as needed
• Maintain clear technical documentation of designs, revisions, and test results

Essential Qualifications

Bachelor's degree in Mechanical Engineering, Mechatro Role & responsibilities

Preferred candidate profile

• 2+ years of hands-on experience designing and building physical mechanical/robotic systems (substantial academic project work will be considered)
• Working proficiency in an MCAD tool such as SolidWorks, Fusion 360, or Creo
• Practical experience with motor control stepper, servo, or BLDC — including driver selection and tuning
• PLC programming experience (ladder logic or structured text)
• Working knowledge of embedded C/C++ on microcontrollers (STM32, ESP32, or similar)
• Understanding of RS485/CAN/Modbus communication protocols
• Ability to perform kinematic calculations for multi-DOF mechanisms
• Comfortable reading electrical schematics and basic PCB layouts
• Familiarity with GD&T, tolerancing, and manufacturing methods (CNC machining, 3D printing, sheet metal)
• Strong documentation habits and comfort working from vendor datasheets/manuals independently
• Experience with version control (Git) is a plus

Good to Have

• Experience designing end-effectors or gripper mechanisms
• Exposure to safety-rated E-stops or interlocks on physical machines
• Prior experience in a regulated or safety-critical engineering environment

What We're Looking For

Someone who is equally comfortable at a CAD workstation and at a workbench with a multimeter or oscilloscope in hand — not purely a designer or purely a coder, but someone who can own a mechanism from concept through to a working, controlled machine.
