Embedded Software Engineer (m/f/d) for Satellite Telecom Payloads (Software Developer)

Your Tasks

Embedded Software Engineering

• Development of low-level embedded software for On-Board systems (C, C++ or Rust), bare-metal, RTOS, or embedded Linux
• Design and implementation of payload-proximate control and configuration software for reconfigurable telecom payloads
• Design and implementation of interfaces between payload electronics, On-Board-Processing, and the onboard computer in close cooperation with payload engineering, systems engineering, and hardware and FPGA teams
• Consideration of real-time requirements, deterministic behavior, and limited resources (CPU, memory, bandwidth)

Software Defined Radio / Software Defined Networking

• Development and integration of embedded software for the control and configuration of SDR functions
• Assessment of control and management logic for beamforming, Adaptive Coding and Modulation (ACM), and channel configuration
• Close coupling of embedded software with digital signal processing (DSP) and FPGA- or ASIC-based payload components
• Analysis, evaluation, and integration of payload-internal data and packet routing and the dynamic configuration of data paths within the satellite, taking into account satellite-specific constraints (latency, availability, deterministic behavior)

Your Qualifications

Technical

• Degree in telecommunications, electrical engineering, computer science, systems engineering, or comparable
• Experience in at least three of the following disciplines: - telecommunications engineering, digital signal processing, or payload technologies
• Software development (embedded, low-level, C, C++, Rust)
• Network and routing protocols
• On-Board communication interfaces (Ethernet, SpaceWire/SpaceFibre, CAN, serial protocols)
• Practical understanding of relevant satellite telecom standards, e.g., DVB-S / DVB-S2(X)
• Knowledge of modern mobile communication concepts in a payload context (5G/6G architecture, Non-Terrestrial Networks (NTN))
• Ability to translate complex telecom concepts into software specifications
• Understanding of real-time requirements and deterministic systems

Nice-to-Have

• Experience with network simulation tools (NS-3, OMNeT++)
• Knowledge of MPSoCs and the toolchains used
• Experience with safety/security mechanisms
• Specification and verification of requirements according to ECSS or DO-178B
• Experience in AI-based telecom methods (routing, beamforming, SDR/SDN)

Personal

• Strong communication skills and enjoyment of interface-oriented work
• Systems thinking and a structured way of working
• Very good English skills; German is a plus
• High quality awareness as well as strong teamwork and communication skills combined with enthusiasm for your own work
