Principal Mechanical Engineer, Off-Planet Robotics

ICON is looking for a Principal Mechanical Engineer for Off-Planet Robotics to assist in our R&D efforts.  As the Principal Mechanical Engineer for Off-Planet Robotics, you will be responsible for the development of conceptual and detailed designs of spacecraft and planetary systems, conduct trade studies and ideation exercises, and participate in our design review and systems engineering processes, and ultimately fly the hardware you have designed.  This role is based locally in ICON’s Austin, TX campus, and will report to the Director of Off-planet Systems in the Strategic R&D Department.



  • Manage engineering standards across the Off-Planet Group.
  • Contribute to the development of a robotic platform for construction applications, focusing on motion platforms and dynamic fluid systems.
  • Design and create prototypes using in-house and external fabrication.
  • Specify robotic servo-driven actuators using industry standards for aerospace applications, including mobile (rover-based) robotics, and large format, long reach robotic actuators.
  • Run FEA and CFD analysis to provide safe and reliable engineered solutions for use in space.
  • Provide hands-on, troubleshooting, and build support as well designing, implementing, and integrating solutions in a fast-paced environment with a quick AGILE development cycle.
  • Create design solutions utilizing engineering methods with good documentation processes.
  • Collaborate with cross-functional, multidisciplinary teams to procure, fabricate, test, and ultimately fly the hardware you have designed.
  • Perform a wide range of tasks on a daily basis (e.g. Transition from office work to field work at a moment’s notice).
  • Establish individual and team goals consistent with overall company OKRs.
  • Mentor engineers in their career development.



  • B.S. degree or higher in Mechanical or Aerospace Engineering.
  • 10+ years of recent experience designing aerospace or equivalent type mechanical system elements within aircraft, spacecraft, or launch vehicles.
  • Past design experience in extreme thermal environments.
  • Strong mechanical design and integration skills using 3D modeling tools.



  • M.S. or PhD in Mechanical or Aerospace Engineering.
  • Strong thermal analysis skills.
  • Familiarity with serial robotic arm operations and design constraints.
  • Ability to earn trust, maintain positive and professional relationships, and contribute to a culture of inclusion.
  • Experience in aerospace actuation design.
  • Experience in formal systems engineering: requirements development, implementation, verification, system integration, qualification and release.
  • Experience in spacecraft systems design.
  • Experience in Solidworks.
  • Experience in structural FEA and CFD using ANSYS, or similar tools.
  • Work performed in an environment requiring exposure to fumes, odors, noise, and outdoor conditions.
  • Physical effort may be required for the handling of supplies or materials (up to 50 lbs unassisted).

Solving one of the most challenging problems humanity faces requires a level of diversity across disciplines. ICON believes that by being a non-homogenous organization, we can capture unique perspectives, educational backgrounds, and ideation. We strive to be inclusive and seek team members who share our passion for the mission within the mission: building robust and diverse teams to help us prevail in the face of our challenges. 

We're a team of varied backgrounds, countries, and experiences, and we believe our differences make us stronger as we tackle some of the most challenging problems of our time.


Every startup wants to change the world, but we genuinely believe we're not being hyperbolic when we say this technology has the potential to reinvent human shelter, dramatically improving quality and resiliency while driving down costs to make housing affordable for everyone. We believe in harnessing the power of construction technology for the good of all humanity, both here on Earth and off-world. And while we get excited about R&D accomplishments in the lab, we get more excited when we see our work out in the real world, printing real homes for real people.

We work hard because we know what we are doing can reshape the way we live as a species. And it doesn't hurt that it's super fun. Where else do you get to play with giant robots and see the results of your work manifest in beautiful full-scale buildings that didn't exist before—and that someone can now call home?
