About the role

• Spacecraft Orbiter GNC Engineer developing Guidance, Navigation, Control software for lunar lander. Collaborating with engineers and performing testing, validation, and troubleshooting activities.

Responsibilities

• Develop orbiter GNC design and perform GNC-related analysis (such as guidance law design and analysis, control law design and performance analysis, thruster duty analysis, DV analysis, attitude dynamics analysis, sloshing and flexible dynamics, navigation filter design, covariance analysis, various GNC sensor evaluation, etc) by using control engineering tools as well as software development activities.
• **• Verify and validate the designed and implemented GNC algorithm by software test and simulation. Support the software test plan and execution for the GNC related functions and evaluate the test result from GNC design perspective, from unit and functional to systems tests. Be engaged in Model-In-the-Loop (MIL), Software-In-the-Loop (SIL), Processor-In-the-Loop (PIL) and Hardware-In-the-Loop (HIL) simulation campaign and exhaustively validate the design algorithm.
• **• Conduct and support pre, post and during operations flight analysis activities and participate in flight operation as a member of orbiter GNC teams. Develop flight operation procedures and support interface and tool design with the ground system from GNC perspective as collaboratively working with the system and operation team.
• **• Perform troubleshooting of GNC FSW algorithms and components and propose solutions to mitigate errors and misbehaviors in the GNC subsystem
• **• Document the technical specifications of the GNC subsystem with a deep understanding of the functions and relations with other subsystems.

Requirements

• 5+ years of experience of Attitude and Orbit Control Subystem (AOCS) or Guidance, Navigation, and Control (GNC) subsystem engineering
• **・Experience in developing navigation algorithms (extended Kalman filter, orbital attitude and position calculations etc.) for spacecraft
• **・Experience in developing attitude control algorithms (PID control, thruster commanding, modulation and allocation, etc.) for spacecraft
• **・Experience of 6DOF Simulations (state propagation, dynamics and hardware modelling and close loop integration) for spacecraft
• **・Experience of C/C++, Python, Git
• **・Enthusiastic attitude and good team player
• **・Excellent communication skills
• **・Business level English
