At the mission design team I am in charge of evaluating the feasibility to achieve mission objectives at spacecraft and constellation level. This implies using tools to dimension the spacecraft and the constellation systems to comply with mission requirements. - Technically support tender proposal writing to fulfill customer requirements. - Perform subsystems configuration analysis to comply with requirements - Evaluate mission feasibility with Model Based Systems Engineering approach using custom developed python apps and AGI STK Engine - Development of ConOps for Comms, ELINT and Optical Missions

In my role of Systems Engineering at Satellogic I strongly contributed to implement the Hosted Payloads Program as a very versatile hosting alternative solution for the market. With a combination of mechanical modularity and adapted COTS electronics, integration times shortened from project kick off to 6 months or less.At the Hosted Payloads Program I have been working in the integration of several payloads involving comms, optical and edge computing applications for internal and external customers.In all these projects I have contributed with:- Definition and deployment of System Concept of Operations (ConOps).- Development and tracking of requirements, validation plans, and test data to ensure the design meets customer objectives- Assistance with design, integration, test plan development and execution of complex projects- Technical Risk identification, tracking and mitigation management.- Use of Model Base development tools to model complex systems to guide the requirements definition and design activities- Coordination of design input from multiple engineering disciplines from within the company and from external suppliers & customers- Generation and maintenance of systems documentation such as Interface Control Documents and User Manuals.- Design and development of hardware, systems, and validation testing setups- Support on COTS components reworking strategy for space environment compatibility.- Development of qualitative and quantitative analysis to ensure a design meets or exceeds customer requirements- Documentation and reporting project status and results both internally and externally- Providing design, development, integration, and test support for customers
