Mechanical Engineer

GRU builds off-world habitats using in-situ resource utilization technology, turning local material into building material.

We are landing on the Moon in 2027: our first mission will turn lunar regolith into bricks and demonstrate our modular pressurized habitat system. A second mission will begin laying the hotel’s foundation in a lunar cave. A third mission will open the first lunar hotel, targeted 2032.

We don’t stop at Moon hotels. GRU’s long-term plan:

1. Build the first hotel on the Moon. GRU solves off‑world surface habitation.
2. Build America’s first Moon base: roads, mass drivers, warehouses, and physical infrastructure.
3. Repeat on Mars and build the first cities there.
4. Own property on the Moon and Mars as these economies grow.
5. Reinvest profits into resource utilization systems on the Moon, Mars, asteroids, and beyond—reaching our final form: Galactic Resource Utilization.

GRU Space is backed by investors in SpaceX + Anduril, and is part of Nvidia’s Inception program.

Your product will land on the Moon next year.

You’ll design, build, and test our 2027 Lunar Payload: the one that manufactures humanity’s first bricks on the Moon and deploys an inflatable habitat bladder. This is hands-on, full-lifecycle hardware engineering at a pace most aerospace companies can’t keep up with.

What you’ll do:

• Own the mechanical design of the payload from concept through flight hardware.
• Rapidly prototype, test, break things, and iterate.
• Manage ICD with the lunar lander provider and be the primary point of contact.
• Run and interpret structural/mechanism analysis to support design trades.

What we’re looking for:

• Deep fluency with CAD and FEA tools: you think in 3D and can back it up with analysis.
• Experience designing spaceflight hardware end-to-end (build, test, deploy).
• Comfort with mechanisms: actuators, seals, deployables, pressure systems, end effectors, and more.
• You’re using the latest AI tools every day (i.e., Opus 4.6/GPT 5.4, in appropriate harness) to massively increase your output and do things you otherwise couldn’t.
• You’ve built flight hardware before.

If you want to maximize the probability that humanity becomes interplanetary in your lifetime, apply and share a portfolio of the technical work you’re most proud of.

We’re building the first hotel on the Moon, so our tech is focused on off‑world habitation: inflatable, pressurized habitats that can survive vacuum, regolith, radiation, and extreme thermal swings.
