Senior Software Engineer, 5G Protocol Stack

Ready to make connectivity from space universally accessible, secure and actionable? Then you’ve come to the right place! E-Space is bridging Earth and space to enable hyper-scaled deployments of space-powered Internet of Things (IoT) solutions and services. We are fundamentally changing the design, economics, manufacturing, coverage limitations and service delivery associated with traditional satellite and terrestrial IoT systems. By building a highly-advanced low Earth orbit (LEO) space system—with a unique antenna design, highly sustainable spacecraft system and low-cost, small portable end-user devices—we can extend global satellite coverage, capacity and connectivity beyond legacy space services to provide a new kind of IoT platform that lets users sense, track, connect and act on information gathered, anywhere. We’re intentional, we’re unapologetically curious and we’re 100% committed to saving space, protecting our planet and turning connectivity into actionable intelligence. As a Senior Software Engineer, 5G Protocol Stack, you will design, develop, integrate, and validate UE and gNB protocol stack software for 5G NR and/or LTE systems. You will work across one or more 3GPP protocol layers and collaborate closely with PHY, RF, and Core Network teams to deliver production-quality embedded software. This role requires strong expertise in C/C++ development, POSIX environments, Linux-based embedded systems, and deep familiarity with 3GPP protocols. You will take ownership of complex software components and contribute to system-level integration and testing. This position is based in Duisburg, Germany.
