Satellite Technical Lead
About the job
ispace is looking for Satellite Technical Lead to join our growing team in Tokyo. 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.
