Spacecraft Firmware Engineer

ICON is looking for a Spacecraft Firmware Engineer I to be a part of our ongoing R&D efforts beyond Earth. As a Spacecraft Firmware Engineer at ICON, you will be responsible for writing, testing, and verifying software/firmware for embedded systems and other computers within ICON’s spaceflight/testing stack. This role is based locally in ICON’s Austin, TX laboratories, and will report to the Director of Off-planet Systems in the Strategic R&D Department.



  • uC whispering: writing and flashing custom firmware to custom chips.
  • Develop and maintain bespoke drivers for ADC, DAC, SPI, I2C, UART, and network peripherals.
  • Debug issues at the hardware and software boundary.
  • Maintain cross functional communication: you will have direct feedback into hardware design and must be conversant in systems engineering.
  • Define requirements, then design, develop, and verify low level software for safety critical avionics.
  • Create prototypes to prove out the architecture/design concepts and quantify technical risks.
  • Specify hardware and compute architectures for complex robotic motion systems.



  • B.S. degree in computer engineering, electrical engineering, computer science, mathematics, physics, aerospace, or related field.
  • Demonstrable software development experience at the hardware software boundary.
  • Strong software development skills, particularly in C/C++.
  • Demonstrated ability to bridge knowledge gaps without assistance.



  • Experience with spaceflight rated software and software quality processes.
  • Understanding of messaging frameworks in high latency and delay tolerant networking environments.
  • Experience in real-time and/or safety-critical software development.
  • Experience with networked distributed systems.
  • Understanding of autonomy frameworks. 
  • 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?
