Join 1cFE

We are a small, technical team using frontier backcasting to focus on the few levers that move fusion LCOE. You will own hard problems, run open analyses, and ship evidence that moves the field forward.

Open roles

General Applications

We welcome exceptional general applications even when a specific role isn’t listed. If you are motivated by abundance, open science, and cost-first thinking, we want to hear from you.

How we work

• LCOE is the north star
• Cost realism over elegance
• Risk first, then speed
• Open science: code, data, and notes are public, negative results are valuable
• High agency, low coordination overhead
• In person at Astera’s HQ in Emeryville, CA
