Senior FPGA Engineer

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.

As a Senior FPGA Engineer, you will lead the design, implementation, integration, and verification of FPGA-based architectures supporting Inversion’s next-generation re-entry vehicles. You will work within the Avionics team to develop high-performance digital systems for RF, communications, telemetry, and real-time signal processing applications across both flight and ground hardware.

This role is ideal for an experienced engineer who can translate system requirements and signal processing concepts into robust FPGA implementations, while driving hardware bring-up, verification, and end-to-end integration across multidisciplinary teams. 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 hardware they create, including design, development, integration, verification, and troubleshooting.
