Job description

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 Mechanical Design Engineer at Inversion, you will play a critical role in the design, packaging, and rapid iteration of hardware across multiple spacecraft and hypersonic development programs. This role spans flight hardware, prototype systems, integration support, and tooling that helps programs move quickly from concept to build. You will work closely with cross-functional teams to solve hard packaging and manufacturability problems while driving designs toward real hardware. In this role, you will:

• Design mechanical systems, structures, brackets, enclosures, mounts, and mechanisms across multiple spacecraft and hypersonic programs.
• Own CAD models, drawings, release packages, and bill of materials for prototype and flight-like hardware.
• Support prototype design, hands-on integration, fit checks, and issue resolution during build.
• Provideadditionaltooling design bandwidth for assembly, integration, and test activities as needed.
• Drive design trades across performance, manufacturability, schedule, and cost.
• Work closely with manufacturing, test, supply chain, and technician teams to bring designs from concept through fabrication and integration.
• Partner with outside vendors and suppliers to source parts, review manufacturability, and accelerate development.

Required Qualifications:

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or equivalent experience.
• 5+ years of applicable experience in mechanical design, integration, and hardware development.
• Experience using Siemens NX or similar CAD software.
• Strong GD&T, tolerance stack-up, and drawing release fundamentals.
• Experience taking hardware from concept through fabrication, assembly, and integration.
• Familiarity with common aerospace fabrication methods including machining, sheet metal, welded assemblies, and prototype hardware builds.
• Demonstrated excellent verbal and written communication skills.
• Proven ability to work effectively in a fast-paced environment.
• Must have the ability to obtain and maintain a U.S. government Secret/Top Secret security clearance.

Desired Qualifications:

• Experience with spacecraft, launch, reentry, hypersonic, or other high-performance aerospace systems.
• Experience supporting prototype builds and rapid design iteration in a hardware-rich environment.
• Experience designing tooling, fixtures, or support equipment for integration and test.
• Experience using hand calculations and/or FEA to inform mechanical design decisions.
• Prior experience working in startups and/or small independent teams.
