Refine with filters →Radio Management Specialist
iSpaceispace, inc. Japan Engineering office is looking for a talented Radio Management Engineer to join the team developing ITU and Radio License Application. As part of the mission and project management team, you will create the necessary ITU APIs for lunar landers and other spacecraft being developed, as well as handle domestic radio license applications. Acting as the liaison with the Ministry of Internal Affairs and Communications, you will prepare the necessary application documents for radio licenses and collaborate with relevant government agencies to carry out the application process for ITU radio licenses. You will also be responsible for applying for experimental radio stations and space radio stations necessary for lunar landers and other spacecraft being developed, serving as the point of contact with the Ministry of Internal Affairs and Communications and government agencies regarding radio license matters. Additionally, you will evaluate radio wave interference and plan radio inspections and related activities in cooperation with system/subsystem/RF communication engineers and ground station engineers. You will prepare and plan for the necessary radio licenses during mission flights and conduct in-orbit inspections for final license acquisition. You will submit CCSDS SCID applications to SANA through JAXA. Furthermore, you will provide technical support to the business team for the expansion of future lunar communication systems.
Senior Mission Engineer
iSpaceispace, inc. is looking for a senior mission engineer to join our growing team. As a Senior Mission Engineer, you will serve as one of the technical and programmatic leaders responsible for delivering successful lunar and deep-space missions. Working within the Mission Management organization, you will integrate engineering, program execution, and mission objectives to ensure the spacecraft is delivered within technical, cost, schedule, and mission performance constraints. Mission Engineers are responsible for making mission-level technical and programmatic recommendations by coordinating multidisciplinary engineering teams throughout the complete spacecraft lifecycle—from mission concept through launch and mission operations. Unlike traditional subsystem or systems engineering roles, Mission Engineers maintain a mission-wide perspective and balance competing technical, schedule, cost, and risk considerations to achieve overall mission success. If you are a systems thinker who naturally considers mission success above subsystem optimization, possess strong technical leadership with the ability to influence without direct authority, demonstrate excellent judgment when balancing technical performance, cost, schedule, and mission risk, have the ability to make timely, data-driven decisions under uncertainty, are comfortable operating in a fast-paced, multidisciplinary environment with evolving mission priorities, and have a passion for advancing lunar exploration and enabling successful space missions, join our team on our journey to the moon!
Satellite Technical Lead
iSpaceispace is looking for a Satellite Technical Lead to join our growing team in Tokyo. The Satellite Lead is a senior, technology-driven leadership role responsible for the end-to-end execution of satellite system development and mission design, with primary accountability for technical coherence, system-level decision making, and engineering leadership. This role sits at the intersection of satellite system engineering and project management, ensuring that mission requirements, technical design, schedule, cost, and risk are continuously balanced and optimized. The successful candidate will act as a technical authority and system integrator, leading cross-functional engineering teams and making critical technical trade-off decisions that enable both mission success and long-term business viability. This position emphasizes technical leadership and system responsibility rather than direct people management.
