Subsystem Engineer - Data Systems, Operations & Advanced Networking Testbeds

Join the team responsible for the design, evolution, and operation of mission-critical data systems supporting human spaceflight at the Columbus Control Center., In this role, you will work at the intersection of high-reliability operations, low-latency networking, and experimental R&D, contributing both to today’s operational excellence and to tomorrow’s space communication architectures.

Your main tasks will include:

• Operate and maintain the DaSS subsystem in a 24/7 mission-critical environment, ensuring high availability, performance, and compliance with customer and mission requirements.
• Design, implement, and operate SatCom networking testbeds to support validation, experimentation, and performance analysis of emerging space communication technologies.
• Analyze system behavior, diagnose complex issues, perform root cause analyses, and support configuration changes, migrations, and operational readiness activities.
• Develop automation tools and scripts (e.g., Bash, Python, Java, C/C++) to support operations, testing, monitoring, and system performance analysis.
• Contribute to engineering activities, technical documentation, knowledge sharing, and collaboration with internal teams, contractors, and external partners to continuously improve mission-critical systems.

We are looking for graduates in Computer Science, Electrical Engineering, or a related field with background and interest in system engineering, networking, embedded or ground systems., * Strong expertise in Linux environments (preferably SLES) and experience with high availability services.

• Solid programming skills in C/C++ and Java, complemented by scripting experience in Bash and Python.
• Good understanding of networking concepts and protocols, including TCP/IP, UDP, routing, and WAN/MPLS technologies.
• Experience with hardware/software interfaces and system-level debugging in complex technical environments.
• A hands-on troubleshooting mindset with the ability to analyze and resolve issues across software, operating system, network, and platform layers.

We will also value previous experience, and knowledge in:

• CCSDS and SatCom standards, protocols, and specifications, including CCSDS O3K, ESTOL, DTN, Space Packet, and CADU.
• Experience with performance-critical or low-latency systems, testbeds, and protocol benchmarking.
• Exposure to SatCom operations, experimental networking, or research-driven technology prototyping.
• Interest in connecting operational systems with R&D activities and future-oriented technology validation.
