Mission

We are automating construction end to end to usher in a new era of abundance and beauty in the physical world in the coming decades. Over the past fifty years, the West’s ability to design and build large scale infrastructure has atrophied, and the entire industry has become less productive. With decaying infrastructure, power shortages, and an aging workforce, the only way through is to hyper-scale development with technology at a rate never before seen.

Our team believes that this is the most important work of our lives, and there’s no more significant place to spend our time than on solving these problems. We believe in the sacrifices that we must make to achieve our mission and build a world of abundance. We believe the future can be amazing, but only if we work gut-wrenchingly hard to make it so. Our work is bigger than all of us, and our obsession with manifesting is what drives us. Roughly 50% of our team are former founders, and we strive for technical excellence, but quell our egos to ensure that the best ideas always win.

We acknowledge the long and arduous path ahead to achieve our ambitions; that many of the most difficult challenges have yet to even be revealed to us; that the chance of failure is not only possible, but likely. Most of all, we believe that there is no other option: we will either revolutionize how humanity builds or die trying.

Role Description

We are hiring a Software Engineer where you will work in a cross-discipline environment, building world-class full-stack software in partnership with our hardware and analysis engineers, and ultimately to support our customers. You will have an extremely high level of autonomy over software architecture, performance, and implementation for our product, where we leverage AI to automate every step of the engineering process to produce end design deliverables for the construction of large scale capital projects such as utility scale power and data centers.

This role is based in-person in San Francisco, CA.

What we're looking for

  • have experience building full-stack applications, database, and cloud infrastructure entirely yourself
  • live at the frontier of AI coding agent model capabilities, and actively try to push the boundaries
  • have experience building engineering or manufacturing software for products in the physical world
  • excitement to work in a fast-paced, high-performance environment, and embrace extreme ownership
  • the ability to prioritize impact by ruthlessly finding the bottlenecks to so to solve the most important problems
  • hands-on builders that can speak to the excruciating minutia and details of their work, and excited to execute instead of manage/organize others work.
  • mission alignment and desire to build a future of abundance

Bonuses

  • worked in the motorsports, defense, aerospace, manufacturing, robotics, or other real-world industries
