Avionics Embedded Software Engineer II

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 Embedded Software Engineer II at Inversion, you will report directly to the Director of Engineering, Avionics. In this role, 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.

• 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 telemetry, command and control, health monitoring, fault management, and data logging systems.
• Design and execute unit tests, integration tests, and Hardware-in-the-Loop (HIL) verification campaigns.
• Debug complex software and hardware interactions using oscilloscopes, logic analyzers, protocol analyzers, JTAG debuggers, and software instrumentation tools.
• Collaborate closely with electrical, systems, manufacturing, integration, and flight operations teams to rapidly identify and resolve vehicle-level issues.
• Participate in software design reviews, architecture reviews, code reviews, and flight readiness reviews.
• Support vehicle integration, environmental testing, flight test operations, and mission execution activities as required.

• Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, Aerospace Engineering, or a related technical discipline.
• Typically 2+ years of professional experience developing embedded software for aerospace, defense, robotics, automotive, or other high-reliability systems.
• Strong proficiency in modern C and C++ development.
• Experience developing software for…
