• Support new business opportunities and technical proposals defining preliminary RF architectures assessing technical feasibility estimating development needs and risks and contributing to technical proposals compliance matrices and customer presentations.

• Define manage and maintain RF subsystem requirements interfaces verification criteria and technical documentation.

• Define develop and maintain RF subsystem architectures throughout the project lifecycle including frequency plans RF chains interfaces redundancy concepts operational modes and associated technical budgets.

• Perform and review RF system analyses and budgets including link budgets gain noise figure output power losses linearity spurious emissions filtering and frequency conversion.

• Coordinate RF engineering activities and ensure alignment between internal teams suppliers and project needs.

• Manage technical interfaces with other spacecraft disciplines including thermal mechanical electrical/electronics digital/FPGA EMC AIT and systems engineering.

• Coordinate technically with external suppliers and subcontractors including requirements flow-down technical follow-up design reviews technical clarifications and acceptance of deliverables.

• Act as an RF technical interface with the customer supporting technical meetings design reviews action tracking and resolution of technical issues.

• Support component and equipment selection and evaluate supplier solutions against RF and system requirements.

• Define and coordinate RF verification and test activities including unit subsystem and payload-level testing.

• Review test plans procedures test results anomalies and non-conformances ensuring proper requirement verification and closure.

• Support and participate in AIT and environmental test campaigns including RF performance verification before and after environmental testing.

• Identify and manage RF technical risks dependencies assumptions trade-offs and critical interfaces.

• Prepare and participate in project milestones and reviews such as SRR PDR CDR TRR QR and AR.

• Ensure technical consistency and traceability between customer requirements system requirements RF design supplier specifications and verification evidence.
