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 Orbiter Guidance, Navigation, and Control Software Engineer to join our growing team in Tokyo.

In this role, you will be developing the orbiter Guidance Navigation Subsystem for the lunar lander. Perform design analysis related to orbiter GNC and detailed design of GNC algorithms based on higher-level requirements. Perform algorithm implementation and testing in coordination with software engineers and GNC engineers. Participate in the testing, verification and validation phase of the GNC flight software. Support flight software integration activities and perform troubleshooting and testing, as well as 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開発を行う。軌道系GNCに関する設計解析、上位要求に基づくGNC算術処理則の詳細設計を行う。ソフトウェアエンジニアやGNCエンジニアと協調してアルゴリズムの実装、試験を行う。GNCフライトソフトウェアの試験、検証および妥当性確認活動に参加する。フライトソフトウェア統合活動を支援し、トラブルシューティングと試験を実施するとともに、ミッション運用および準備活動を行う。

Key responsibilities

    (1) 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.

    (2) 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.

    (3) 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.

    (4) Perform troubleshooting of GNC FSW algorithms and components and propose solutions to mitigate errors and misbehaviors in the GNC subsystem

    (5) Document the technical specifications of the GNC subsystem with a deep understanding of the functions and relations with other subsystems.

    (1) 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。

    (2) ソフトウェア試験およびシミュレーションによりGNCアルゴリズムの妥当性確認および検証を行う。GNC関連機能のソフトウェアテスト計画および実行を支援し、ユニットテスト、機能テストからシステムテストに至るまで、GNC設計の観点からテスト結果を評価する。Model-In-the-Loop (MIL), Software-in-the-loop (SIL), Processor-in-the-loop (PIL), Hardware-In-the-Loop (HIL)などの静的閉ループ試験を行い、GNCサブシステム設計の妥当性確認と検証を行う。

    (3) フライト前、運用中、フライト後の解析を行う。軌道系GNCチームとして運用に従事する。システムチームおよび運用チームとともにGNCの運用手順を開発し、地上システムとのインタフェースおよびツール設計を支援する。

    (4) GNC FSWアルゴリズムおよびコンポーネントのトラブルシューティングを実施し、GNCサブシステムにおけるエラーや誤動作を軽減するための解決策を提案する。

    (5) GNCサブシステムの技術仕様を、その機能および他サブシステムとの関連性を深く理解した上で文書化する。
