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

OHB SE; Bremen; On-site; EUR 70,000 - 100,000; Full time

Job summary

OHB SE in Bremen is seeking a Requirements Engineer for spacecraft software systems. You will develop and maintain top-level requirements, structure complex behaviour into functions, interfaces and data flows, and define interactions between processors, avionics units, payloads and ground systems.

You will ensure traceability from system requirements to software architecture and verification, and support the refinement of the Requirements Baseline into detailed specifications.

Qualifications

• An 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.
• Strong focus on quality, teamwork and communication, with passion for the work.
• Very good written and spoken English.

Responsibilities

• 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.

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.
