Senior Flight 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 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.

Key Responsibilities:

• 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.
