Engineer III - Controls

Role Overview

We are seeking a Control Systems Engineer with 4–6 years of experience in mobile robots, EV platforms, or autonomous mobility systems (UGV/ UAV). Candidates should hold a Master’s degree in Control Systems, Signal Processing, Robotics, Mechatronics, or related fields, with strong skills in C++, ROS/ROS2, ros2_control, Nav2, motor control (FOC), and robot dynamics.

The role involves developing and optimizing control algorithms for differential-drive, skid-steer, tracked, or Ackermann UGVs, integrating autonomy modules, and collaborating across hardware, perception, and embedded teams.

Key Responsibilities

1. Vehicle Control & Motion Systems

• • Develop and tune control algorithms (PID, MPC, feedforward).
  • Integrate and calibrate FOC-based motor controllers (BLDC/PMSM/Hub).
  • Build and validate vehicle dynamics and actuator models.

2. ROS/ROS2 & Autonomy Integration

• • Develop ROS 2 control nodes in C++.
  • Implement controllers using ros2_control (DiffDrive, Ackermann, manipulators).
  • Configure and tune Nav2 (planners, controllers, costmaps, BTs).
  • Own bring-up, launch flows, and integration with perception/localization.

3. Manipulator & Actuation Control

• • Implement kinematics, Jacobians, and trajectory execution.
  • Develop joint-level control and safety interlocks.

4. EV Vehicle Control Unit (VCU)

• • Implement torque control, throttle mapping, regen braking, and diagnostics.
  • Work with CAN, RS485 and integrate BMS, motor drivers, and VCUs.

5. Modelling, Simulation & Testing

• • Develop models using MATLAB/Simulink or Python.
  • Validate in Gazebo/Ignition simulation environments.
  • Perform HIL/SIL, real-world testing, tuning, and calibration.

6. Cross-functional Collaboration

• • Work with mechanical, electrical, autonomy, and embedded teams.
  • Contribute to safety reviews, FMEA, and requirement discussions.

Required Qualifications

• • Master’s degree in relevant engineering field.
  • 3–4 years experience in control systems for robots/EVs/Flight Controls.
  • Strong C++ (OOD, real-time constraints).
  • Hands-on ROS 2, ros2_control, TF, URDF/Xacro.
  • Experience with Nav2 setup/tuning.
  • Proficiency in FOC, BLDC/PMSM control, motor modelling.
  • Knowledge of vehicle dynamics, state estimation, sensor fusion.
  • Experience with CAN/RS485, integration of VCU, BMS, and motor controllers.
  • Localization algorithms (EKF, UKF, Visual SLAM).

Preferred Qualifications

• • Manipulator control (MoveIt/MoveIt2).
  • Real-time systems or embedded MCU experience.
  • Exposure to EV HV/LV architecture and functional safety.

Soft Skills

• • Strong analytical and mathematical skills.
  • Good documentation and system design discipline.
  • Ability to work in fast-paced R&D environments.
  • Team-oriented with strong cross-functional communication.
