Turning Space into a Transportation Layer for EarthWho 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 a Senior Digital Signal Processing Engineer, you will lead the development, implementation, and validation of real-time digital signal processing algorithms supporting Inversion's next-generation re-entry vehicles. You will work within the Avionics team to develop DSP solutions for communications, telemetry, sensing, and RF-adjacent applications across both flight and ground systems.
This role is ideal for an experienced engineer who can translate complex signal environments and system requirements into robust algorithms, simulation tools, and deployable implementations across software, FPGA, GPU, or embedded hardware platforms. You will help develop critical hardware and systems for cutting-edge maneuverable reentry vehicles - advancing one of the most capable reentry vehicle platforms ever developed.
You will be a key member of the Avionics team, reporting directly to the Director of Engineering, Avionics. Our engineers are responsible for the complete lifecycle of the systems they create, including concept development, modeling, implementation, integration, test, and operational support.
