Senior Mechanical Engineer

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 

S

enior

 Mechan

ical

 Engineer

 at Inversion, you will 

own 

cradle to grave 

development of mission-critical 

hardware

 on one of the most capable reentry vehicles ever develope

d. 

This role spans flight hardware, prototype systems, tooling, and integration support that enables the pro

gram to move quickly from concept to build. 

You’ll

 drive 

mechanical 

system archi

tecture 

working closely with cross-functional teams to solve complex packaging and manufacturability problems while driving des

igns toward real hardware

.

This role demands a 

versatile, 

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 be a key member of the 

Mechanical

 team, reporting to the 

Director of Mechanical.

Key Responsibilities

• Design and develop 

  flight-critical mecha

  nical systems, brackets, enclosures, mounts, and mechanisms

   from concept through flight qualification

• Lead mechanical design of 

  subsystem integration and vehicle packaging

  , ensuring hardware comes together as a high-performing, coh

  esive system

• 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

  5

  + years of 

  professional 

  experience

  de

  veloping hardware

   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

• Familiarity

   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

Desired Qualifications

• Master’s degree in Aerospace Engineering

  , Mechanical Engineering, a related field, or equivalent experience

• Demonstrated history of 

  mechanical design ownership from cradle to grave

• 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
