Job summary

Inversion is seeking a Staff Mechanisms Engineer to own cradle‑to‑grave development of mission‑critical mechanisms for advanced reentry vehicles. You will shape mechanical architecture, perform analyses, and lead testing across structures, avionics, propulsion, TPS, and GNC to ensure seamless integration.

The role demands hands‑on design work, architecture leadership, first‑principles analysis, hardware testing, and cross‑functional collaboration, reporting to the Director of Mechanical.

Qualifications

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or related field.
• 8+ years designing, analyzing, and testing mechanisms and moving assemblies for aerospace/defense.
• Strong mechanical design with 3D CAD proficiency (NX, CATIA, SolidWorks).
• Hands-on structural and thermal analysis using FEA tools (ANSYS, Abaqus, NASTRAN).
• Experience designing for harsh environments (vacuum, extreme temps, shock, vibration).
• Proficiency in GD&T and detailed engineering drawings.

Responsibilities

• Design and develop flight-critical mechanisms from concept to qualification and production.
• Perform structural/thermal analysis to validate designs for hypersonic and spaceflight environments.
• Lead test campaigns including environmental qualification and life-cycle testing.
• Create detailed drawings, ICDs, and design specs.
• Collaborate with manufacturing/integration teams to build, troubleshoot, and iterate hardware.
• Drive design reviews and trade studies; coordinate with suppliers for procurement.
• Support vehicle integration and provide engineering support during assembly, test, and launch.

Job description

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.

What You'll Do

As a Staff Mechanisms Engineer at Inversion, you will own cradle to grave development of mission-critical mechanisms on one of the most capable reentry vehicles ever develope d. You’ll drive mechanical system archi tecture and collaborate with stakeholders across structures, avionics, propulsion, TPS, and GNC to ensure seamless integration o f the mechanical assemblies into our next-generation vehicles.

This role demands a hands-on engineer who can fluidly move between high-level system architecture, detailed design work, first-principles analysis, hardware testing, and cross-functional collaboration. You will own designs from initial concept through qualification and into production. You will be a key member of the Mechanical team, reporting to the Director of Mechanical.

Key Responsibilities

Design and develop flight-critical mechanisms including actuators, deployment mechanisms, separation systems, and cartridge actuated devices from concept through flight qualification

Perform detailed structural and thermal analysis using FEA and analytical methods to validate designs against hypersonic and spaceflight environments

Develop and execute comprehensive test campaigns including functional testing, environmental qualification (vibration, shock, thermal, TVAC, EMI/EMC), life cycle testing, and acceptance testing

Create detailed engineering drawings, assembly procedures, interface control documents (ICDs), and design specifications

Work hands-on with manufacturing and integration teams to build, troubleshoot, and iterate hardware rapidly

Drive design reviews and present technical trade studies to inform architecture and component selection decisions

Coordinate with suppliers and vendors for custom component procurement, ensuring adherence to schedule and technical requirements

Support vehicle integration activities and provide technical expertise during assembly, test, and launch operations

Required Qualifications

Bachelor’s degree in Aerospace Engineering , Mechanical Engineering, a related field, or equivalent technical experience

Typically 8 + years of professional experience designing , analysising , and testing mechanisms and moving mechanical assemblies (MMA) for aerospace, defense, or similarly demanding applications
