?We're Hiring: Robotics Engineer (Motion Control) ?

Location:
Hubli, Karnataka

Experience:
2+ years Domain: Motion Control | Embedded Firmware | Actuators and Sensors ❗ Freshers are not eligible. ❗ Candidates must be willing to relocate. About this role You will own the motion system of a two-axis, remotely operated, stabilised platform for defence use. That covers the software (control loops and real-time firmware) and the hardware (motors, drives, sensors, harnessing) that keep a payload pointed precisely at a target. You need working depth in both software and hardware. Core mechanical design is handled by a separate Mechanical Design Engineer. This is not a ROS demo or simulation-only role. Your code will drive real motors on hardware that goes to field trials. What you'll be doing 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 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 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 firmware and hardware Software
- Embedded C/C++ on microcontrollers, with an RTOS or bare metal
- Control fundamentals: PID, cascaded loops, feedforward, and BLDC/PMSM control including FOC
- IMUs, encoders and sensor fusion (complementary or Kalman filters)
- MATLAB/Simulink or Python for modelling, tuning and test scripts 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 read electrical schematics and mechanical drawings
- Comfortable with oscilloscopes, power supplies and data loggers Positive to have
- Experience with gimbals, pan-tilt units, antenna positioners, drone flight controllers or robotic arms
- Working knowledge of CAD (SolidWorks or similar)
- Exposure to ROS 2, MIL-grade harnessing, JSS 55555 or MIL-STD-810 Why join us
- Work on real defence hardware that goes to field trials, not demos or PoCs
- Own a complete subsystem from design to deployment
- Work in a small team directly with mechanical, electronics and software engineers About Astr Defence Astr Defence is an award-winning Indian defence manufacturer building next-generation armaments and counter-UAV systems for modern battlefield requirements. ?Apply: send
