Role summary

Inversion is seeking a Staff Mechanisms Engineer to lead the development of mission-critical mechanisms for advanced reentry systems. This role involves cradle-to-grave ownership, from concept through qualification and production, requiring a hands-on engineer proficient in mechanical design, structural/thermal analysis (FEA), and environmental testing. You will collaborate across teams, drive design reviews, manage suppliers, and ensure seamless integration of mechanical assemblies into next-generation vehicles operating in extreme reentry conditions. The position is based in Playa Vista, CA, and requires in-office presence.

Turning Space into a Transportation Layer for Earth

Who We Are:

Inversion builds advanced reentry systems to deliver next-generation capabilities from space. Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach. Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds. Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics.

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 developed. You’ll drive mechanical system architecture and collaborate with stakeholders across structures, avionics, propulsion, TPS, and GNC to ensure seamless integration of 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

Strong mechanical design skills with proficiency in 3D CAD software (NX, CATIA, Solidworks, or similar)

Hands-on experience with structural and thermal analysis using FEA tools (ANSYS, Abaqus, NASTRAN, or equivalent)

Demonstrated ability designing for harsh environments including vacuum, extreme temperatures, shock, and vibration

Deep understanding of mechanical systems including mechanisms, actuators, fasteners, bearings, seals, and material properties

Experience with environmental testing (shock, vibration, TVAC) and qualification programs for spaceflight hardware

Proficiency creating detailed engineering drawings with GD&T and other technical documentation

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

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

Experience with spacecraft and aerospace mechanisms such as deployment systems, control surfaces, separation mechanisms, solar array drives, gimbal systems, or cartridge actuated devices

Familiarity with propulsion system components including valves, pressure vessels, feed systems, and fluid interfaces

Experience supporting prototype builds and rapid design iteration in a hardware-rich environment

Prior work in fast-paced startup environments or small multidisciplinary teams

Our office headquarters is located in Playa Vista, CA. This position requires in office presence.
