Staff Mechanisms Engineer

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

• 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,   gimb a l 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
