ispace is seeking a Senior Avionics Design Engineer to lead the development of spacecraft avionics hardware for lunar landers, satellites, and future space systems. This is a hands-on technical leadership role responsible for the full lifecycle of avionics hardware, from requirements definition and design through manufacturing, testing, qualification, and flight support.

The successful candidate will own key avionics products, drive technical decisions, solve complex engineering challenges, and mentor other engineers while working closely with multidisciplinary spacecraft teams.

Our teams work bilingually and Japanese and/or English ability is required.

Key Responsibilities

Own the full lifecycle of spacecraft avionics hardware, from requirements definition and design through implementation, manufacturing, integration, verification, qualification, and flight support.
Lead gate reviews and technical milestones, including coordinating required inputs across disciplines, developing review documentation and compliance evidence, presenting technical content, and driving review actions through closure.
Lead technical execution for avionics products, making key design decisions, conducting trade-off studies, resolving complex technical issues, and ensuring performance, reliability, manufacturability, and compliance requirements are met.
Collaborate across spacecraft disciplines, including flight software, communications, power, propulsion, GNC, payloads, and system engineering teams to coordinate technical interfaces, drive issue resolution, and achieve system-level review and delivery milestones.
Support project execution, including planning, risk management, procurement activities, supplier coordination, and technical stakeholder engagement.
Provide technical leadership across the avionics team, by supporting other avionics engineers in technical decision-making, design reviews, problem resolution, and the delivery of high-quality engineering products, while contributing to engineering best practices, knowledge sharing, and the development of other engineers.
