Spacecraft Engineer - Water Transport & ISRU (Equity / Early Growth Stage)

Compensation: 0.0% – 1.0%

We’re scaling our space infrastructure company, actively hiring mission-driven builders for equity-only roles with rapid growth ahead.

After 5 years of development, we have one mature spacecraft design (~40,000 engineering hours and millions in equivalent value) plus four additional designs in early stages. We have a committed core team of 13 and are now in aggressive expansion mode as we push multiple NASA and other grant applications, investor conversations, and asset stabilization to fuel growth.

Mission: Near-term focus: Water transport spacecraft for LEO, cislunar space, and delivery to Mars and lunar outposts, collecting and moving ice/water resources from space.

Longer-term: ISRU operations at distant destinations including the subsurface oceans of Ganymede, Europa, and Enceladus, plus inspiring imagery of those worlds.

Parallel nuclear programs: Earth-based nuclear electric generation, nuclear-powered spacecraft, and lunar surface nuclear systems.

• We’re also exploring AI + physics-informed simulation tools to accelerate development as we scale.
• We are hiring across multiple disciplines and plan to grow

Skill sets:

• Aerospace / Mechanical / Propulsion Engineers
• Nuclear engineers & systems specialists
• Electrical / Power systems engineers
• Software, simulation & AI/ML engineers (physics-informed modeling a big plus)
• Mission designers, orbital analysts
• Video / imagery engineers

Reality check (important):

• We are currently all equity / shares only (including the founder).
• No salaries at this stage.
• Cash is tight while we close grants and funding, but we are moving fast to change that.
• This is high-ownership startup work with real upside.
• If you need immediate stable salary, this may not be the right fit right now
• if you want meaningful equity in a rapidly growing space resources company, let’s talk.

What you get: Significant equity stake, direct impact on foundational technology for space settlement, and the chance to help build a much larger team and capability.

South Texas base but strong remote contributors welcome

• (U.S. time zones + ITAR compliance required).
