Software Systems Engineer for Satellite Software (m/f/d)

We develop distributed on-board software for the next generation of satellites. Almost every aspect of a modern satellite depends on software. Software turns mission objectives into behaviour: it controls the spacecraft, connects its equipment, manages data, handles failures and enables autonomous operation far beyond the reach of immediate human intervention. As a Software Systems Engineer, you will shape this behaviour before it becomes architecture and code. You will translate operational needs and system-level requirements into a clear, consistent and verifiable Software Requirements Baseline. Working with system, software and verification engineers, you will use requirements, scenarios and models to establish a shared understanding of the intended behaviour.

Your Tasks

• Understand the intent behind operational concepts, stakeholder needs and system requirements
• Develop and maintain top-level requirements for the spacecraft software system
• Structure complex behaviour into functions, interfaces, modes, scenarios and data flows
• Define interactions between distributed processors, avionics units, payloads and ground systems
• Use behavioural and interface models to test assumptions and identify gaps
• Maintain traceability from system requirements to software architecture and verification
• Bring the relevant disciplines together to resolve unclear, conflicting or changing requirements
• Support the refinement of the Requirements Baseline into detailed software specifications

Your Qualifications

• A degree in computer science, software engineering, electrical engineering, aerospace engineering or a related discipline
• Several years of experience in embedded software, distributed software architecture or software-intensive systems engineering with a good understanding of hardware/software interaction
• Practical experience with requirements-based verification
• The ability to structure complex technical information and express it through requirements, scenarios or models
• An interest in working across system, software and verification disciplines
• A strong focus on quality, as well as excellent teamwork and communication skills, combined with a passion for your work
• Very good written and spoken English

Useful Additional Experience

• Experience in some of the following areas would be helpful, but we do not expect you to bring all of them:
• Requirements engineering for spacecraft, avionics or other regulated embedded systems; ECSS, DO-178 or comparable engineering and assurance processes
• Requirements management with DOORS, DOORS NextGen, Polarion or a comparable tool
• Behavioural modelling with SysML, UML, Capella, state machines or sequence diagrams
• Interface specification and end-to-end analysis for distributed systems
• Fault detection, isolation and recovery, redundancy or degraded-mode operation
• Real-time operating systems and on-board communication technologies
• Knowledge of German

You will initially work on defined areas of a requirements baseline coordinated by an experienced lead engineer. You will receive support in learning our space-specific methods, tools and processes, and can progressively take responsibility for larger areas of the spacecraft software specification.
If the role interests you but your experience does not cover every item in the “Useful Additional Experience” section, we would still be pleased to hear from you.
