Job description

We are looking for a Senior Control Engineer to design, simulate, and implement high-performance motion control algorithms and state estimation frameworks for advanced articulated platforms. In this role, you will lead the core algorithmic design for dynamic balance, whole-body motion, trajectory optimization, and sensor-guided navigation.

Key Responsibilities and Core Tasks

• Design and implement model-based control algorithms (MPC, WBC, LQR, Inverse Kinematics) for complex articulated systems (humanoid, bipedal, or multi-DOF manipulators).
• Develop multi-sensor fusion pipelines using Kalman Filtering (EKF/UKF) or Factor Graphs to integrate IMU, encoder, force/torque, depth camera, and LiDAR telemetry.
• Write production-grade C++ code targeting real-time OS (RTOS/PREEMPT_RT Linux) and fieldbus protocols (EtherCAT, CANopen) for sub-millisecond execution loops.
• Build digital twins in dynamic physics engines to test disturbance rejection, terrain handling, and network jitter resilience.
• Lead on-hardware tuning, system identification, and physical bench testing to resolve non-linearities, backlash, and torque ripple.

Required Qualifications

• Master or Ph.D. in Control Engineering, Robotics, Mechatronics, Electrical Engineering, or a related field.
• 5+ years of hands-on experience developing and deploying motion control systems on physical robotic hardware.
• Mastery of rigid-body dynamics, spatial vector algebra, state-space control theory, and non-linear control systems.
• Advanced proficiency in modern C++, Python, and ROS 2.

Preferred Skills:

• Experience with force-controlled/impedance-controlled actuation or contact-rich manipulation.
• Familiarity with wireless network integration (5G-Advanced, 6G, URLLC) for cloud-offloaded robotics computation.
