Avionics Mechanical Engineer - Summer Internship 2027

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.

As an Avionics Mechanical Engineering Intern, you will support the design, build, integration, and testing of mechanical hardware that enables Inversion’s flight avionics systems. You will sit within the Avionics team and work closely with electrical, RF, embedded software, manufacturing, and vehicle engineering teams to develop robust mechanical solutions for flight-critical electronics and avionics systems.

You will gain hands-on experience taking hardware from early design concepts through detailed design, prototyping, fabrication, integration, and environmental testing. This is a practical, hardware-focused internship for students interested in aerospace structures, mechanical design, electronics packaging, thermal management, mechanisms, and rapid hardware development.
