By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions.\nThe company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach.\nHeadquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.\nPosition Overview:\nAs an RF Engineering Intern, you will support the verification, validation, integration, and performance characterization of flight and ground RF/Telemetry systems for Inversion’s next-generation re-entry vehicles. You will sit within the Avionics team and work closely with engineers on hands-on RF testing, antenna and GPS integration, communications system validation, and ground station compatibility efforts, helping take systems from benchtop validation through integrated hardware testing and mission-readiness verification.\nYou will be a member of the Avionics team, supporting the development, test, integration, and troubleshooting of critical communications hardware and systems for cutting-edge maneuverable reentry vehicles. This is a practical, lab-heavy internship for students interested in spacecraft communications, telemetry, antennas, and RF system integration in a fast-paced aerospace environment.\nKey Responsibilities:\nWork closely with RF engineers and cross-functional teammates to build practical understanding of how aerospace RF and telemetry systems are developed, tested, integrated, and prepared for flight applications.\nPerform component-, subsystem-, and system-level RF test and measurement activities using standard laboratory equipment such as spectrum analyzers, network analyzers, signal generators, oscilloscopes, and power meters.\nSupport over-the-air and antenna test activities, including range setup and validation, as needed.\nSupport GPS testing and integration for the Arc vehicle.\nSupport ground station compatibility testing, including potential travel to test sites.\nHelp test and evaluate in-house RF hardware, including SDR-based systems.\nCollect, process, and document RF test data and support generation of test reports and summaries.\nAssist with test automation and analysis tools using Python, MATLAB, or similar tools.\nRequired Qualifications:\nMust be enrolled in a bachelor’s, master's or doctorate degree program in an engineering, physics or math discipline.\nGPA of 3.0 or above.\n3+ months of applied engineering experience (internship, laboratory, and personal/team project experience is applicable).\nCoursework or project experience in RF, antennas, electromagnetics, or communications systems.\nStrong problem-solving, written and verbal communication skills, with the ability to present technical results clearly to multidisciplinary teams.\nDesired Qualifications:\nHands-on familiarity with RF lab equipment such as a spectrum analyzer or VNA.\nExperience with Altium, HFSS, or similar RF/PCB design tools.\nCompleted an RF or antenna course.\nExperience designing a circuit board.\nExperience designing a simple microwave antenna or filter.\nHands-on experience through Formula SAE, student rocketry, CubeSat, robotics, or similar engineering projects.\nPrevious internship experience at a space, aerospace, or hardware startup.\nExperience with Python or MATLAB for test automation or data analysis.\nExperience with antenna test methods.\nFamiliarity with S-band and L-band communication or telemetry systems.\nFamiliarity with S-parameters and their use in evaluating RF component and system performance.\nOur office headquarters is located in Playa Vista, CA. This position requires in-office presence.\nThe California annual base hourly rate for this role is currently $38-$41. Pay Grades are determined by role, level, location, and alignment with market data. Individual pay will be determined on a case-by-case basis and may vary based on the following considerations: interviews and an assessment of several factors that are unique to each candidate, job-related skills, relevant education and experience, certifications, abilities of the candidate and internal equity. \nITAR Compliance:\nTo conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you 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.
