He or she translates mission objectives into system requirements, defines the concept of operations and the approach strategy for rendezvous and proximity operations (RPO), and ensures traceability to the platform, payload, and ground segment., Define and develop the concept of operations (ConOps) for missions (Inspection, life extension). - Perform mission analyses: approach and rendezvous strategy, budgets, system simulation. - Define nominal and degraded operational scenarios, including fault detection, isolation, and recovery (FDIR) strategies at the mission level. - Elaborate the end-to-end mission timeline, from launch to end of life. - Assess mission risks and propose mitigation strategies. Mission Requirements & System Performance - Translate customer and programmatic needs into mission requirements and high-level system specifications. - Flow down mission requirements to the platform, payload, and ground segment, and ensure traceability in the requirements baseline. - Define and monitor mission performance budgets (delta-V, autonomy, availability, navigation accuracy). - Participate in design trade-offs impacting mission performance. Operations Support, Verification & Interfaces - Interface with GNC and flight dynamics teams on the approach strategy and safety constraints. - Coordinate with the ground segment and operations teams on the preparation and validation of mission procedures. - Contribute to verification and validation (V&V) planning at the mission level and to associated reviews (SRR, PDR, CDR, ORR). - Serve as the technical focal point for the customer on mission aspects. - Capitalize on lessons learned from previous missions for future developments. ## Related Videos - [ShapeShift: Reinventing Agile for a B2B SaaS Scale-Up](https://www.wearedevelopers.com/videos/1655-shapeshift-reinventing-agile-for-a-b2b-saas-scale-up) - [The 2026 Talent Pivot: Essential Trends for an Evolving Workforce](https://www.wearedevelopers.com/videos/100098-the-2026-talent-pivot-essential-trends-for-an-evolving-workforce) - [From Punch Cards to AI-assisted Development](https://www.wearedevelopers.com/videos/611-from-punch-cards-to-ai-assisted-development) - [Robots are coming into the wild!
