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 Mechanical Engineer Intern at Inversion, you will contribute to the development of mission-critical hardware for one of the most capable reentry vehicles ever developed. You’ll work alongside experienced mechanical engineers to help take flight hardware, prototype systems, tooling, and integration equipment from early concepts to real, testable hardware.

This is a hands-on role for a highly motivated engineer who is excited to learn quickly, solve difficult physical problems, and see their work built and tested. You may contribute across the engineering lifecycle from CAD design and drawings to analysis, procurement, assembly, testing, and vehicle integration.

You will be a member of the Mechanical team and report to the Director of Mechanical.

Key Responsibilities

Support the design and development of mechanical systems including brackets, enclosures, mechanisms, tooling, and test equipment

Create and revise 3D CAD models, assemblies, engineering drawings, and bills of materials

Perform engineering analysis using a combination of first-principles calculations, hand analysis, and FEA to assess structural and thermal performance

Support the planning, setup, execution, and documentation of hardware test campaigns, including functional, vibration, shock, thermal, and environmental testing as applicable

Work directly with manufacturing, technicians, and integration teams to build, inspect, troubleshoot, and iterate hardware

Help create and maintain engineering documentation, including assembly procedures, test plans and reports, interface documents, and design specifications

Take ownership of well-scoped engineering projects while communicating progress, risks, and technical findings clearly

Required Qualifications

Currently pursuing a Bachelor’s or master’s degree in mechanical engineering, Aerospace Engineering, or a closely related technical discipline

Demonstrated interest and aptitude in hands-on engineering through coursework, project teams, research, internships, personal projects, machining, robotics, rocketry, automotive, or similar experience

Experience using 3D CAD software such as NX, CATIA, SolidWorks, Creo, or similar

Fundamental understanding of mechanical engineering principles, including statics, mechanics of materials, machine design, heat transfer, and material properties

Demonstrated ability to take initiative, learn quickly, and work through ambiguous technical problems

Strong attention to detail and commitment to high-quality engineering work

Clear written and verbal communication skills and the ability to work effectively on a fast-moving, collaborative team

Desired Qualifications

Prior experience designing, building, and testing complex physical systems including rocketry, CubeSats, robotics, Formula SAE, Baja, UAVs, marine vehicles, lab research, or personal projects

Familiarity with GD&T, engineering drawings, tolerancing, and design for manufacturing and assembly

Exposure to structural or thermal analysis tools such as ANSYS, Abaqus, NASTRAN, or similar

Experience with machining, sheet metal, composites, additive manufacturing, or other fabrication processes

Familiarity with test instrumentation, data acquisition, or laboratory testing practices

Passion for aerospace hardware and a desire to contribute to ambitious, real-world engineering programs
