## Job description

**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.
