Senior Mission Systems Engineer 

• 7+ years of experience in mission design and systems engineering 

• Experience supervising a team of mission systems engineers 

• Responsible for delegation of technical responsibilities 

• Leads the definition of mission architecture. 

Main responsibilities: 

• Identify and characterize mission needs, expected performance, and safety goals. 

• Define the system-level architecture and develop the initial functional specifications. 

• Lead the definition and flow-down of high-level mission and system requirements to subsystems (Platform, Propulsion, Payload, GNC, Robotics) and maintain the System Requirements Document (SRD) throughout the project lifecycle. 

• Lead system-level trade-offs and architecture down-selection based on a balanced analysis of performance, budget, schedule, and technical risk. 

•  Define and manage the interfaces for the Launch Segment and Ground Segment, assessing their impact on the mission profile and spacecraft design. 

• Own and manage the Interface Control Documents (ICDs) to ensure seamless integration between the Platform, Propulsion and Payload (Robotics). 

• Produce and maintain all critical system budgets, including Mass, Power, Propellant, Data, Link budgets. 

• Monitor and report on system margins against industry standards (e.g., ECSS). 

• Define the Verification & Validation (V&V) process, supervise Model-in-the-Loop (MiL) Software-in-the-Loop (SiL), Hardware-in-the-Loop (HiL) verification process. 

•  Oversee Assembly, Integration, and Test (AIT) activities, oversee the qualification campaign and environmental tests (Thermal Vacuum, Vibration, EMI/EMC). 

• Act as the primary technical investigator for system-level anomalies, identifying causes and suggesting robust solutions during both development and mission operations. 

• Develop the Concept of Operations (ConOps) for all mission phases, with a focus on the Rendezvous and Proximity phases. 

• and validate proximity trajectories to ensure mission safety while optimizing for d-V efficiency. 

• Conduct continuous analysis of system performance, identifying bottlenecks and implementing optimizations to meet mission-specific KPIs. 

•  Support the coordination and planning of spacecraft procurement and mission milestones. 

• Provide technical leadership in writing project proposals, funding documents, and bidding contracts for customers and institutional partners. 

• Maintain transparent and regular technical reporting to the internal team and external customers, ensuring alignment on mission progress and risk posture. 

Requirements: 

• Master’s degree in Aerospace Engineering, Systems Engineering, or a related field. 

• Familiarity with space standards (e.g., ECSS, NASA, MIL-STD). 

• Solid background in orbital mechanics and space mission analysis. 

• Good written and spoken English. 

Nice to have: 

• Experience with rendezvous and proximity operations (RPO) or formation flying. 

• Experience in Mission Analysis area. 

• Experience with ECSS standards and early-phase mission documentation. 

• Previous involvement in ESA, institutional, or R&D space projects. 

We offer: 

• Interesting work in a dynamically developing company in the space sector. 

• Salary adequate to qualifications and responsibilities. 

• Opportunity to participate in projects for the space sector within international consortia. 

• Opportunity to participate in an individual development program.
