You will lead the end-to-end development of the lunar lander’s orbiter system—including design, verification, and operations—from the perspective of the Guidance, Navigation, and Control (GNC) subsystem. Define and manage requirements for the GNC subsystem, including sensors, software and other hardware components. Manage technical coordination and interface alignment with other subsystems. Manage the integrity and performance of GNC algorithms in the FSW development and deliverables. Support mission operations and preparation activities. 月着陸船の軌道系誘導航法制御サブシステムの観点から、軌道系GNCサブシステム全体開発（設計、検証、運用）を担当する。センサー、ソフトウェアおよびその他のハードウェアコンポーネントを含む軌道系誘導航法制御サブシステムの要求定義、管理を行う。各サブシステムとの技術調整、インターフェース調整を担当する。FSW開発および成果物におけるGNCアルゴリズムの完全性と性能を管理する。ミッション運用および準備活動を支援する。 Key responsibilities (1) Join our engineering team overseeing the entire lunar lander orbiter system, supporting end-to-end development—design, verification, and operations—from the perspective of the Guidance, Navigation, and Control (GNC) subsystem. (2) 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. (3) Design the system and the orbiter Guidance, Navigation, and Control (GNC) subsystem using FMECA (Failure Mode, Effects, and Criticality Analysis) and MCFMA (Mission Critical Fault and Mitigation Analysis) methodologies. (4) Plan, implement, and execute comprehensive verification and validation activities for the orbiter system, spanning from component-level (GNC sensors) to system-level tests (SCLT, DOLT, DCLT). These include nominal, off-nominal, and fault simulations for orbit operations. (5) Define OGNC flight software/algorithm requirement specifications (6) Develop GNC subsystem requirements, design, constraints, and operations with a deep understanding of the technical coordinations and interface alignments with systems engineering and other subsystems (propulsion, structures, thermal, avionics, flight software, mission planning, and operations). (7) Define OGNC unit specifications as flow-down of the OGNC system requirements and design specifications (8) Support lander system design with providing GNC feasibility studies and design inputs for the key system design trade-offs such as actuator and sensor configuration and selection, component layout, controlability, delta V, RCS budget, etc. (9) Support the selection, verification, and operational readiness of key orbiter system components—such as Sun sensors, IMUs, star trackers and propulsion—from both technical and theoretical perspectives. (10) Design and support throubleshooting activities of GNC FSW algorithms and components and propose solutions to mitigate errors and misbehaviors in the GNC subsystem. (11) Document the technical specifications of the GNC subsystem with a deep understanding of the functions and relations with other subsystems. (1) 月着陸船のシステム全体を統括するエンジニアリングチームの一員として、主に誘導航法制御サブシステムの観点から、軌道系GNCサブシステム全体開発（設計、検証、運用）をサポートする。 (2) 軌道系誘導航法制御に関する設計解析（誘導制御則設計、制御性能解析、スラスタ制御解析、DV解析、姿勢力学解析、スロッシング、柔軟ダイナミクス解析、航法フィルタ設計、誤差共分散解析、GNCセンサ評価など）を制御工学ツールとソフトウェア開発活動を通して実施する。 (3) FMECA（Faulure Mode, Effects, and Criticality Analysis）およびMCFMA（Mission Critical Fault and Mitigation Analysis）に基づくシステムおよび軌道系GNCサブシステムのロバストな設計を行う。 (4) コンポーネントレベル（GN ...
