Job summary

Cowboy Space Corp. is seeking a hands-on RF engineer to own selection, development, integration, and radio systems for our launch vehicle and spacecraft. You will translate mission requirements into a reliable communications system from ground to vehicle.

You will lead RF system trades, maintain link budgets, and bring RF hardware through bring-up, qualification, and flight support. This is an individual contributor role coordinating with multiple teams.

Qualifications

• Bachelor's degree in electrical, computer, or aerospace engineering, physics, or a related field.
• 8+ years of experience developing or integrating RF communications systems for space applications, including hands-on hardware verification and environmental qualification.
• Experience translating communications requirements into radio and antenna selections, link budgets, and hardware or system-level verification plans.
• Proficiency with RF laboratory equipment, including vector network analyzers, spectrum or signal analyzers, signal generators, power meters, and oscilloscopes.
• Working knowledge of digital communications and modulation, RF measurement methods, and EMI/EMC mitigation through grounding, shielding, filtering, and cable routing.
• Ability to use Python or MATLAB for test support and data analysis, document results clearly, and resolve integration issues with suppliers and engineers from other disciplines.

Responsibilities

• Define RF requirements and maintain link budgets for telemetry and command links, including antenna performance, losses, interference, and ground-station compatibility.
• Evaluate radios, antennas, and RF components for the required bands from UHF through Ka-band; assess performance, interfaces, qualification evidence, and integration risks.
• Own radio and RF hardware bring-up, configuration, characterization, and integration with flight software and vehicle avionics, working with suppliers to resolve interface and performance issues.
• Develop and execute acceptance and qualification plans for RF hardware, including functional, vibration, shock, thermal, thermal-vacuum, and EMI/EMC testing as applicable. Coordinate facilities and equipment, lead test readiness, and maintain verification records.
• Develop RF test benches, fixtures, cabling, calibration methods, and automation with the test team; identify testability needs early and support repeatable acceptance testing for subsequent builds.
• Lead RF anomaly investigations across hardware, software, test equipment, and ground interfaces, verify corrective actions, and support flight operations.
• Prepare technical inputs for FCC licensing and coordinate compatibility testing with ground-station providers. Resolve RF interference and coexistence issues with payload and vehicle teams.
• Partner with the navigation sensor owner on GNSS antenna and RF interfaces, interference, and compatibility while maintaining clear ownership of the communications system.
