Headquartered in Finland and operating internationally with offices in Finland, Poland, Spain, Japan, the UAE, Greece, and the US, our diverse team of more than 900 experts from nearly 60 countries shares a bold mission: to enhance life on Earth by delivering reliable, data-driven solutions. At ICEYE, we foster a culture of curiosity, innovation, and collaboration, pushing the boundaries of what's possible in space technology to solve the world's toughest challenges.

Why Join ICEYE?

At ICEYE, we're not just launching satellites — we're redefining what's possible with SAR technology. Join a team of passionate innovators solving real-world challenges and making a tangible impact. We foster a dynamic and inclusive environment where your ideas are valued, your growth is supported, and your contributions truly matter. With continuous learning opportunities, cutting-edge projects, and collaboration with industry-leading experts, you'll have the chance to grow, innovate, and shape the future of Earth Observation.

What will you do in this role?

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.

Key Responsibilities

• 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

Requirements & Qualifications

• 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

Nice to Have

• 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)

What's In It for You?

• 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.
