A SAR satellite company building an on-site software integration and test function in Tokyo, with security screening required, suggests it is standing up local manufacturing and government-facing operations in Japan rather than just selling data there.
Team: Global Manufacturing Organization – AIT Engineering
Location: Tokyo, Japan
Working model: On-site
Employment is subject to applicable security screening (incl. SUPO, where required).

ICEYE is seeking a Software AIT (Assembly, Integration & Testing) Engineer to build the test software backbone of our satellite production in Japan. You will design and develop, from scratch, the test framework used by all AIT activities, own the simulators that enable hardware-in-the-loop testing, and debug flight software behavior during integration. Working closely with Electrical and Mechanical AIT engineers, you will turn manual procedures into automated, repeatable test sequences and give the team the data and dashboards they need to verify every spacecraft. The framework you build is intended to become the reference for ICEYE AIT globally.
Design, develop and maintain the AIT test framework from scratch, including architecture, test execution, sequencing, logging and result reporting
Define the software stack, tooling and development practices for AIT test software (version control, code review, CI/CD, testing of the test code itself)
Develop and own satellite and subsystem simulators used for hardware-in-the-loop and software-in-the-loop testing
Debug flight software behavior during integration and test, including on-board software loading, telemetry and telecommand anomalies, and OBC-driven subsystem responses, coordinating with Flight Software Engineering on root cause and fixes
Build data pipelines from test equipment and satellite telemetry into InfluxDB, and create Grafana dashboards for test monitoring, trending and system health
Support Electrical and Mechanical AIT engineers by turning their test procedures into automated, repeatable test sequences and providing tools for their test campaigns
Ensure the framework is designed for global reuse: documented, modular, and adoptable by AIT teams in other ICEYE sites
Contribute to production readiness and design reviews (PRR, CDR) by providing feedback on software testability, simulator and test automation requirements
Interface with Global AIT, Flight Software Engineering, Ground Software and Mission Operations teams to ensure alignment on test standards, interfaces and lessons learned
3+ years of professional software development experience, with a focus on test automation, test frameworks or tooling for hardware systems, preferably in aerospace, automotive, robotics or other high-reliability industries
Strong proficiency in Python, including designing maintainable, modular software architectures (not only scripting)
Experience building or significantly extending a test automation framework from the ground up
Experience testing embedded systems or hardware, including communication protocols and interfaces (e.g. UART, SPI, I2C, CAN, Ethernet)
Experience debugging embedded or real-time software in a hardware context
Solid software engineering practices: Git, code review, CI/CD, unit and integration testing
Experience with time-series data and visualization (InfluxDB, Grafana or similar)
Proficient English (written and spoken) for cross-functional collaboration
Experience with spacecraft software or ground segment tools (e.g. CCSDS / PUS telemetry and telecommand, YAMCS, OpenC3 COSMOS)
Experience developing simulators or digital twins for hardware-in-the-loop testing
Experience with instrument control and EGSE automation (SCPI, VISA, programmable power supplies, data acquisition)
Knowledge of C or C++ for reading and debugging embedded flight software
Experience with Linux, Docker and infrastructure as code
Experience with Atlassian Cloud tools (Jira, Confluence)
Proficient Japanese (written and spoken)
A job that matters in a dynamic Defence Technology and Earth Observation environment with a scale-up approach.
An independent role with a supportive and diverse work environment.
Health insurance.
Time for self-development, research, training, conferences, or certification schemes.
Relocation support, where applicable (e.g., flight tickets, accommodation, relocation agency support).
Inspiring, collaborative offices and silent workspaces that enable you to focus.
At ICEYE, diversity is more than just a value — it's our greatest strength. We're dedicated to creating an inclusive environment where every voice is not only heard but celebrated.
