SUPO) The Mission of the Senior Backend Software Engineer You will own the backend systems that let customers plan and manage satellite tasking through Tactical Access, ICEYE's tactical customer access product. Tactical Access is customer-facing on two fronts, API and web, so this role sits at the intersection of backend engineering rigor and product ownership. You will design and operate the services and data models that power satellite tasking for real customers, and you will be trusted to make API design and reliability decisions that customers depend on directly, not just internal consumers. 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.
