Senior Software Engineer

Job Title: Senior Software Engineer- Robotics Location: Redmond , WA (3 days Hybrid) What you'll do Vehicle Control Development Contribute to the design and implementation of the vehicle control architecture. Implement logic on the central high-performance embedded computer running Linux and distributed real-time microcontrollers. ROS2 Control Implementation Implement ros2_control hardware interfaces that abstract complex custom hardware into standard interfaces. Develop firmware and drivers to interface ROS2 with low-level custom hardware boards via: CAN-FD (J1939 / CANopen) I2C SPI UART Algorithm Design Design and tune closed-loop control algorithms (PID, MPC, LQR) to manage vehicle dynamics. Actuate multi-DOF systems with precision and implement controllers within ROS2. Hardware Interface, Sensor Fusion & Instrumentation Integrate sensors including IMUs, encoders, LiDAR, GPS, and pressure transducers. Create accurate vehicle state estimates through sensor fusion. Hydraulic Systems Control Model and control complex non-linear hydraulic systems (valves, pumps, cylinders). Convert digital control commands into fluid power actions. What you'll bring Required Qualifications: Education: BS or MS in Robotics, Computer Science, Mechanical Engineering, Mechatronics, or similar field. Control Theory Expertise: Strong understanding of classical and modern control theory, including vehicle kinematics and dynamics. ROS2 Experience: Proven experience with ROS2, particularly ros2_control, hardware interfaces, and node lifecycle management. Embedded Systems Experience: Experience contributing to distributed control architectures for mobile robots, automotive systems, or heavy machinery. Embedded Protocols: Hands‑on experience with: CAN bus (J1939 or CANopen) I2C SPI

RS485

C/C++ Proficiency: Strong real-time C++ skills (C++20/23) for constrained embedded environments. Preferred Qualifications (Highly Desirable): Hydraulics Experience: Electro-hydraulic control experience in heavy machinery, agriculture, or construction equipment. Safety-Critical Systems: Knowledge of functional safety standards or safety-critical RTOS implementations. Simulation: Experience with URDF and simulators such as Gazebo or Isaac Sim. Microcontrollers: Experience with real-time microcontrollers and application processors, including Yocto Linux. #J-18808-Ljbffr Cogent Infotech Corp
