Relativity Space is building next-generation rockets and spacecraft systems to enable commercial and scientific space missions. As a Senior RF Engineer on the Interplanetary Program, you will own the complete lifecycle of high-reliability RF communication systems for deep-space exploration—from architecture and link budget analysis through hardware design, integration, environmental qualification, and flight operations.
You will design RF systems capable of operating across extreme distances (measured in astronomical units), low signal-to-noise environments, and highly constrained mass and power budgets. Your responsibilities include selecting and integrating RF components (transmitters, receivers, LNAs, power amplifiers, frequency sources, converters), designing passive RF elements (filters, diplexers, couplers, waveguides), antenna design and analysis, and ensuring seamless integration with avionics, optical communications, and spacecraft subsystems. You will collaborate closely with ground station partners (DSN, KSAT) and work hands-on through hardware bring-up, environmental testing, and flight readiness activities.
This is a hardware-first, highly technical role in a fast-moving environment where iteration speed, analytical rigor, and end-to-end ownership are essential. You will solve engineering challenges at the frontier of RF technology, pushing boundaries in radiation tolerance, signal integrity, and system reliability for missions that advance scientific exploration.
Required: Bachelor's degree in Electrical Engineering, Computer Engineering, Physics, or related field; 5+ years of RF communication system architecture, analysis, or component engineering experience. You should have hands-on expertise in at least three of: RF architecture and link budgets for challenging environments; RF system component selection and integration; RF passive component design; antenna design and analysis; RF testing and measurement; or radiation effects on RF systems.
