SUPO, where required) Why this role matters: As a Flight Software Engineer, you’ll help build the embedded software systems powering ICEYE’s SAR satellites. Your work will directly contribute to the reliability, scalability, and performance of flight computers operating in orbit, enabling mission-critical Earth Observation capabilities for customers around the world. Working close to both hardware and software, you’ll help shape the future of spaceborne SAR systems and support ICEYE’s mission to become the global source of truth in Earth Observation. Who We Are ICEYE delivers space-based intelligence, surveillance, and reconnaissance (ISR) capabilities to governments and allied nations. This includes sovereign and turnkey ISR missions leveraging ICEYE’s world-leading synthetic aperture radar (SAR) satellite technology, as well as access to data from the world’s largest SAR satellite constellation. These capabilities enable partners to detect and respond to critical changes anywhere on Earth with unprecedented speed and accuracy, day or night and in any weather, supported by ultra high-resolution imagery and high-frequency revisits. As a trusted partner for defense, intelligence, security, and maritime domain awareness, ICEYE’s near real-time data creates a tactical advantage for mission-critical operations. Designed for dual use, the platform also serves civil protection and commercial users for natural-catastrophe intelligence, insurance, maritime monitoring including oil-spill detection, and finance, contributing to global security and community resilience. ICEYE is headquartered in Finland and operates globally across Europe, North America, the Middle East, and Asia-Pacific.
