? 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

Good 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
