Senior Avionics Test and Integration Engineer

Turning Space into a Transportation Layer for Earth Who We Are: Inversion builds advanced reentry systems to deliver next-generation capabilities from space. Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach. Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds. Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics. What You'll Do As an Avionics Test and Integration Engineer at Inversion, you will report directly to the Director of Engineering, Avionics. In this role, you will be responsible for integrating, validating, and troubleshooting the electrical systems that enable Inversion’s vehicle to fly. You will work at the intersection of hardware design, software, manufacturing, and flight operations, owning vehicle-level checkout, test infrastructure, and hardware verification from development through flight. You will build and operate flight-like test environments, perform qualification and acceptance testing of avionics hardware, integrate avionics into flight articles, investigate anomalies, and help ensure every electrical subsystem is ready for mission operations. This is a highly hands‑on role requiring strong engineering judgment, technical curiosity, and the ability to solve complex system‑level problems under aggressive development schedules. Key Responsibilities Own vehicle‑level integration, checkout, and verification of avionics subsystems including flight computers, power systems, networking equipment, RF systems, sensors, and payload interfaces. Develop and execute electrical integration procedures, acceptance test plans, qualification campaigns, and vehicle checkout operations. Design, build, and maintain avionics test infrastructure including HIL testbeds, bench‑top test systems, test racks, breakout boxes, simulators, and electrical ground support equipment. Support system‑level bring‑up and troubleshooting of flight hardware, including root‑cause investigations involving electrical, software, networking, and mechanical interfaces. Perform electrical verification activities including continuity testing, isolation testing, power‑on validation, sensor calibration, and hardware functional testing. Develop automated test procedures and data collection tools to improve test coverage, repeatability, and operational efficiency. Analyze telemetry, logs, and test data to identify failures, characterize system performance, and drive corrective actions. Collaborate closely with avionics design engineers, embedded software engineers, manufacturing engineers, and vehicle integration teams to rapidly resolve issues and improve product reliability. Support vehicle environmental testing including vibration, thermal vacuum, EMI/EMC, and flight qualification campaigns. Generate clear test documentation including procedures, test reports, discrepancy reports, and non‑conformance investigations. Support launch, flight, and mission operations as required. Required Qualifications Bachelor’s degree in Electrical Engineering, Computer Engineering, Aerospace Engineering, Physics, or a related technical discipline. Typically 5+ years of experience in avionics integration, spacecraft testing, launch vehicle testing, aerospace systems integration, or equivalent high‑reliability hardware environments. Experience integrating and troubleshooting embedded electronic systems and electrical hardware. Strong understanding of electrical schematics, wiring diagrams, interface control documents, and system architectures. Hands‑on experience using oscilloscopes, digital multimeters, power supplies, logic analyzers, network analyzers, and data acquisition equipment. Experience performing system‑level troubleshooting using telemetry, logs, electrical measurements, and root‑cause analysis techniques. Familiarity with common aerospace and embedded communication protocols such as Ethernet, CAN, RS‑422, RS‑485, SPI, I²C, etc. Experience with Python, C++, MATLAB, LabVIEW, or automated test frameworks. Ability to work effectively in a fast‑paced hardware development environment with evolving requirements. Excellent verbal, written, and cross‑functional communication skills. Desired Qualifications Experience with spacecraft, launch vehicles, hypersonic systems, autonomous aircraft, defense systems, or other mission‑critical aerospace platforms. Experience developing, building, and operating Hardware‑in‑the‑Loop (HIL), Software‑in‑the‑Loop (SIL), Iron Bird, or flight simulation environments. Experience with hardware qualification and environmental testing including vibration, thermal vacuum, shock, and EMI/EMC testing. Knowledge of networking technologies including TCP/IP, UDP, multicast, managed switches, and Precision Time Protocol (PTP). Experience working with telemetry systems, mission operations, and flight software verification. Familiarity with aerospace standards such as IPC‑620, IPC J‑STD‑001, NASA workmanship requirements, or military standards. Experience developing electrical ground support equipment (EGSE) and production test systems. Experience supporting vehicle integration campaigns, launch operations, flight tests, or mission readiness reviews. Previous experience in a fast‑paced startup or rapid hardware development environment. Our office headquarters is located in Playa Vista, CA. This position requires in‑office presence.
