Ispace (TYO: 9348) is a global commercial lunar exploration and space infrastructure enterprise headquartered in Tokyo, Japan, with regional subsidiaries operating in Luxembourg and the United States (Denver, Colorado). Founded in 2010 by CEO Takeshi Hakamada, the publicly traded company has raised over $200 million in private equity and government grants from investors including Innovation Network Corporation of Japan (INCJ), Development Bank of Japan (DBJ), Suzuki Motor, and Japan's Space Strategy Fund.

ispace is looking for Spacecraft Descent Guidance, Navigation, and Control System Engineer to join our growing team in Tokyo.

You will lead the end-to-end development of the lunar lander’s landing system-including design, verification, and operations-from the perspective of the Guidance, Navigation, and Control (GNC) subsystem.

Define requirements for the GNC subsystem, including sensors, software and other hardware components, and 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.

月着陸船の着陸系誘導航法制御サブシステムの観点から、着陸系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着陸系誘導航法制御サブシステムの要求定義、管理および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。

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。

Ideal candidate profile:

The ideal candidate has over 5 years of experience in GNC subsystem development, including algorithm design, sensor modelling, and performance evaluation, as well as spacecraft systems engineering with failure mode analysis. The candidate is proficient in C/C++, Python, Git, and understands modern software development practices.

The candidate has hands-on experience with closed-loop test frameworks (MIL/SIL/PIL/HIL), developing models and interfaces for IMUs, star trackers, LiDARs, cameras, and propulsion systems, along with direct involvement in system-level spacecraft testing (SCLT, DOLT, DCLT). Proven capability in vision-based navigation system development is essential.

The candidate is proactive, collaborative, communicates effectively, and operates confidently in business-level English.

Key responsibilities

    (1) Oversee the entire lunar lander landing system, supporting end-to-end development-design, verification, and operations - from the perspective of the Guidance, Navigation, and Control (GNC) subsystem.

    (2) Design the Entry, Descent and Landing (EDL) GNC functions and perform GNC-related analyses (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 and in-house developed software.

    (3) Plan, implement, and execute comprehensive verification and validation (V&V) activities for the landing system, spanning from component-level (GNC sensors) to system-level tests (SCLT, DOLT, DCLT).

    (4) Design frameworks for the GNC FMECA (Failure Mode, Effects, and Criticality Analysis) and MCFMA (Mission Critical Fault and Mitigation Analysis) methodologies and execute fault scenarios for validating landing operations robustness.

    (5) Develop a deep understanding of GNC subsystem requirements, design, constraints, and operations - including vision-based navigation - and manage technical coordination and interfaces alignment with systems engineering and other subsystems (propulsion, structures, thermal, avionics, flight software, mission planning, and operations).

    (6) Define landing GNC flight software/algorithm requirement specifications

    (7) Define landing GNC unit specifications as flow-down of the GNC 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, controllability, delta V, RCS budget, etc.

    (9) Support the selection, verification, and operational readiness of key orbiter system components - such as IMUs, star trackers, LiDARs, cameras and propulsion - from both technical and theoretical perspectives.

    (10) Design and support troubleshooting 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) 月着陸船の着陸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、着陸系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) 着陸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インハウスソフトウェアを通して実施する。

    (3) コンポーネントレベル(GNCセンサー)からシステムレベル(SCLT, DOLT, DCLT)までを含めた着陸システム全体のハードウェアを含めた検証および妥当性確認を計画、実装、実行する。

    (4) 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着陸系GNCサブシステムのロバストな設計を行う。また、着陸運用における故障シミュレーションを含めた検証および妥当性確認を計画、実装、実行する。

    (5) 着陸系GNCのフライトソフトウェア/アルゴリズムの要求仕様を定義する。

    (6) 誘導航法制御サブシステム(GNCセンサー、画像航法システム含む)の要求、設計、制約、運用を深く理解し、システムズエンジニアリングチームおよび各サブシステム(推進、構造、熱、アビオニクス、フライトソフトウェア、飛行計画、運用)との技術調整およびインターフェース管理を行う。

    (7) 着陸系GNCシステムの要件および設計仕様をもとに、着陸系GNCユニットの仕様を定義する。

    (8) アクチュエータやセンサーの構成・選定、コンポーネントの配置、制御性、デルタV、RCS予算など、主要なシステム設計上のトレードオフに関するGNCの実現可能性調査および設計インプットを提供し、月着陸船システムの設計を支援する。

    (9) 月着陸船軌道システムのキーとなるコンポーネント(IMU、スタートラッカー、LiDAR、カメラ)の選定、モデリング、検証、運用を技術的/理論的観点からサポートする。

    (10) GNC FSWアルゴリズムおよびコンポーネントの設計とトラブルシューティング活動を支援し、GNCサブシステムにおけるエラーや誤動作を軽減する解決策を提案する。
