Senior Attitude & Orbit Control System Engineer

Control Engineering | Simulation, Numerical Analysis | Space

Location	Koto-ku, Tokyo
Company	Build constellations of small SAR satellites developed and operated in-house to generate and provide data. Also use their unique data analysis capabilities to provide data-based solutions to the world's various challenges. Established: 2018 Capital: 100 million yen
Job Description	Responsibility: Attitude and Orbit Control System (AOCS) design, analysis, implementation, testing and maintenance. Details of work: - Design, implement, test, and validate algorithms used in the AOCS of their Synthetic Aperture Radar (SAR) satellites, such as: sensor data filtering, orbit and attitude estimation, attitude controller, reaction wheels and magnetorquer control, operation modes control, failsafe mechanisms, etc. - Work closely with the embedded software engineers to integrate the AOCS into the rest of the flight software. - Validate the design through unit testing, Model In the Loop Simulation (MILS), Hardware In the Loop Simulation (HILS), and tests on the physical satellite. - Assist the testing and validation of the AOCS components during the satellite Assembly Integration and Testing (AIT) process. - Model sensors, actuators, and other physical components in MATLAB/Simulink/Simscape and fit the component model using test data. - Take part in the launch campaign: prepare the necessary items for launch operation, monitor the behavior during the critical phase, and provide technical support to the satellite operation team. - Participate in weekly meetings and design reviews. Selling points of the role: - Great opportunity for growth as an engineer. - See the complete lifecycle of a satellite, from the early design to the launch and in-orbit operation. - Work in an international team.
Requirement	Required: - Bachelor’s degree in Aerospace Engineering, Control Engineering, Electrical Engineering, or Robotics Engineering. We will consider an equivalent combination of relevant education and/or experience. - At least 8 years of hands-on experience in the design and validation of control systems, preferably on autonomous systems (satellite, launch vehicle, drone, Unmanned Aerial Vehicle (UAV), self-driving car, robot, etc.). - Thorough understanding of multibody dynamics: coordinate transformation between reference frames, kinematics, conservation of energy and momentum, etc. - Strong analytical and communication skills. - Experience with MATLAB/Simulink. - Experience working with physical sensors and actuators. - Willingness to travel to the company's factory (Yamato-city) on business trips several times a year. Preferred: - Knowledge of orbital mechanics and satellite dynamics. - Experience in the design, implementation and testing of spacecraft attitude and orbit control algorithms. - Experience in modeling physical components such as sensors and actuators in MATLAB/Simulink. - Experience in control law design, beyond classical techniques: non-linear design, optimal design. - Experience in state estimation using Kalman filtering and anomaly detection algorithms. - Experience in model identification. - Knowledge of GNC hardware components such as: reaction wheels, magnetorquers, GPS receivers, gyroscopes, star trackers. - Experience in modeling finite state machines in Stateflow. - Experience programming in C/C++. - Experience in generating C/C++ code from Simulink.
