Responsibilities
Own the architecture, design, development, testing, and operation of next-generation high-reliability RF systems that enable deep-space communication, navigation, and science operations
Work hands-on across the full lifecycle, from concept and link budgets, to working with ground stations (i.e. DSN, KSAT, etc.) through hardware bring-up, environmental qualification, integrated testing, and flight readiness
Partner tightly with avionics, optical comms, and spacecraft REs to ensure our RF subsystem integrates cleanly into the overall spacecraft bus
Solve engineering challenges that push the boundaries of RF technologies: designing for extreme distances measuring in AUs, low-SNR environments, radiation effects, and highly constrained mass/power budgets
Qualification
Required
Bachelor's degree in Electrical Engineering, Computer Engineering, Physics, or a related field
5+ years of experience in RF communication system architecture, analysis, and/or component engineering
Experience with 3 or more of the following: RF architecture & link budgets for challenging environments, Selection, design, and/or integration of RF systems including transmitters, receivers, LNAs, PAs, frequency sources, converters, and front-end architecture, Selection and/or design of RF passive components such as filters, diplexers, couplers, and waveguide components, Antenna design, analysis, and modeling tools, Hands-on testing with RF lab equipment such as spectrum analyzers, VNAs, SDRs, power meters and data recorders, Hands-on integrated testing with ground stations and/or integrated spacecraft RF systems to flow live telemetry and commanding
Experience communicating deeply technical topics with individuals from different disciplines
Preferred
Experience with space environments (radiation effects, thermal extremes, vacuum operation, component derating)
Prior work with deep-space spacecraft comms system design & architecture
Prior work with deep-space ground station networks
Experience with high-gain antennas, phased arrays, or gimbaled antenna systems
Experience designing or validating RF hardware for flight qualification (TVAC, vibe, EMI/EMC)
