ICEYE is a Finnish spacetech company that builds and operates the world's largest SAR (synthetic aperture radar) satellite constellation for persistent Earth observation and intelligence.
- Senior Software Engineer (Networking) - Fleet Control & Satellite Communications - Fleet Automation - Espoo, Finland - Reports to: Engineering Manager of the Fleet Automation team - Permanent | Hybrid - Employment is subject to applicable security screening (incl. SUPO) THE MISSION OF THE SENIOR SOFTWARE ENGINEER (NETWORKING) You will build the networking backbone that keeps ICEYE's satellites talking to the ground. Ground-to-space communication with our SAR constellation runs through the TT&C Gateway. This role plays a central part in evolving that gateway: the socket-level connections, the traffic shaping, the resilience mechanisms that keep communication alive over degraded, low-bandwidth, high-latency links. You will have real latitude to propose architecture and shape design direction, not just implement someone else's spec, and turn hard physical constraints like link availability, bandwidth, and latency into robust, automated software. 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 operates internationally with offices in Finland, Poland, Spain, Japan, the UAE, Greece, and the US. The company has more than 900 employees, inspired by the shared vision of improving life on Earth by becoming the global source of truth in Earth Observation.
