Senior RF Systems Engineer

About the role

As an RF Systems Engineer at Inversion, you will report directly to the Manager of Arc Avionics. In this role, you will be responsible for the development, integration, and verification of the flight and ground RF/Telemetry systems for Inversion’s next‑generation reentry vehicles. You will own the end‑to‑end lifecycle of communication hardware—taking systems from initial link analysis and component selection through to radiation pattern modeling, lab testing, and live mission‑readiness validation.

Responsibilities

• Develop and maintain high‑fidelity communication link budgets, modeling vehicle‑level antenna radiation patterns and simulating RF performance in challenging flight and atmospheric reentry environments.
• Perform trade studies to evaluate, select, and qualify commercial off‑the‑shelf (COTS) and custom RF components, including transmitters, transceivers, Power Amplifiers (PAs), Low Noise Amplifiers (LNAs), and antennas.
• Lead benchtop and vehicle‑level RF testing using standard laboratory equipment, bridging hardware with software by supporting live end‑to‑end telemetry validation.
• Establish and test ground station networks utilizing S‑band and L‑band frequencies to ensure robust link margins at critical elevation angles.
• Partner with software, guidance and control (GNC), power, and mechanical teams to ensure optimal antenna placement, proper thermal dissipation, and structural integrity under environmental stress.
• Lead the gathering of technical data and generating documentation required for regulatory licensing with bodies such as the FCC, ITU, and NTIA.
• Design and own RF test systems and develop comprehensive test plans to qualify hardware across space and reentry environments (thermal, vibration, shock, EMI/EMC, and radiation).

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or equivalent technical experience.
• Typically 5+ years of professional aerospace/defense experience with direct ownership of RF hardware deployment, component qualification, or link architecture.
• Proven experience developing and analyzing RF link budgets under dynamic flight profiles.
• Foundational experience with electromagnetic simulation tools (such as Ansys HFSS) for modeling antenna characteristics or component behavior.
• Demonstrated background in the design of fault‑tolerant and failover‑capable RF systems.
• Proficient using common laboratory equipment such as spectrum analyzers, network analyzers, power meters, oscilloscopes, and data acquisition systems.
• Excellent verbal and written communication skills with the ability to present technical RF concepts to multidisciplinary teams.
• Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.
• Must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State (ITAR compliance).

Desired Qualifications

• Experience testing and integrating S‑band
