? We’re Hiring: Mechatronics Engineer
Experience: 2+ years
Domain: Motion Control | Embedded Firmware | Electromechanical Systems
❗Freshers are not eligible.
❗Candidates must be willing to relocate.
About this role
You will own the motion system of a remotely operated, stabilised pan-tilt platform for defence use. That covers the hardware (motors, drives, sensors, harnessing) and the software (control loops and real-time firmware) that keep a payload pointed precisely at a target.
You need working depth in both hardware and software. Core mechanical design is handled by a separate Mechanical Design Engineer.
This is a hands-on hardware and firmware role, not a simulation or documentation role.
What you'll be doing
Hardware
• Size and select motors, gearboxes, encoders and brakes against torque, speed, accuracy and weight budgets
• Integrate and commission BLDC/PMSM motor drives, IMU and feedback sensors on a two-axis platform
• Define wiring harnesses, connectors and power distribution for a battery-powered system
• Build test rigs and measure backlash, friction,



pointing accuracy and repeatability

Software
• Design position, velocity and current control loops and IMU-based stabilisation
• Write real-time control firmware in C/C++ on microcontrollers (STM32 or similar)
• Implement operator control modes, travel limits and safety interlocks
• Take low-latency tracking commands from the vision software and close the loop on them

System
• Tune the complete system on real hardware for pointing accuracy and smooth tracking
• Support environmental, EMI/EMC and field trials, analyse the logs and fix what they find

Mandatory skills and experience
• 2+ years of hands-on work on robotic or electromechanical products (robotics, gimbals, drones, automation, EV or defence), covering both hardware and firmware

Hardware
• Actuator sizing and selection: BLDC or servo motors, gearboxes, encoders or resolvers
• Motor drivers and interfaces: CAN, RS-422/485, SPI, UART
• Able to re
