Senior Flight Software Engineer

About this role

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 a Senior Flight Software Engineer at Inversion, you will have an instrumental impact on the design, functionality, and performance of our next-generation reentry vehicles. You will own a substantial aspect of the flight software stack that enables our spacecraft to complete its mission of extended operation in space, eventually returning on Earth to be recovered. Your impact will encompass all aspects of fight software, including commanding, telemetry, and implementation of control algorithms running on custom hardware that flies the world’s first reentry vehicle designed for turning space into a viable transportation layer for Earth. You will be a key member of the Processing Core team, reporting directly to the Director of Engineer, Processing Core.

This role is all-encompassing, and includes the complete lifecycle of the vehicle’s software including:

• Owning critical software components for a new vehicle, from initial concept though design, implementation, testing, and deployment

• Writing and testing software for spacecraft, including drivers, networking, fault management, and attitude control interfaces

• Assisting in creating and executing tests, including HITL (hardware in the loop) and HOOTL/SITL (software in the loop) testing, integration testing, and unit testing

• Assisting with the growth and development of the software organization, including conducting interviews and mentoring/onboarding other engineers and interns

We’re a mission-driven team passionate about pushing the limits of space exploration. While there may be moments when the excitement calls for…
