Senior Avionics Embedded Software Engineer

Advanced Reentry Technologies Who We Are: Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. 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. The 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. Headquartered 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. Position Overview: As a Senior Embedded Software Engineer at Inversion you will develop the software that powers and controls Inversion’s hypersonic reentry vehicle. You will work across the full software stack, from low-level hardware interfaces and board support packages to real-time vehicle control, networking, and mission-critical flight applications. You will partner closely with electrical, systems, GNC, and integration engineers to bring up new hardware, develop flight software architectures, and deliver reliable software capable of operating through all phases of flight. This role requires strong ownership, hands-on debugging skills, and the ability to rapidly solve challenging hardware-software integration problems. Key Responsibilities: Design, develop, test, and maintain embedded software for flight computers, avionics subsystems, payload interfaces, and vehicle control systems. Develop high-reliability software in C and C++ for real-time embedded systems operating in mission-critical aerospace environments. Own software development throughout the entire product lifecycle, including requirements definition, architecture, implementation, verification, flight test support, and operational deployment. Develop and maintain Board Support Packages (BSPs), hardware abstraction layers, bootloaders, and device drivers for custom avionics hardware. Perform board bring-up and hardware enablement activities on new processor and FPGA-based platforms. Develop software interfaces for sensors, actuators, radios, power systems, storage devices, and vehicle networks. Design and implement vehicle-wide communication architectures enabling reliable exchange of telemetry, commands, sensor data, and control information across distributed embedded computing platforms using DDS, CoAP, and other modern networking technologies. Support distributed vehicle software architectures including…
