Careers

Help us build the parts of a mind.

Project Ancilla is run by a small team and a circle of partners and investors. If you want to own a real part of a genuinely different architecture — not a slice of a roadmap — we'd like to hear from you.

01 — Why join

What it's like here.

Early

Ground-floor architecture

Calliope is a prototype. The hardest design questions about the tiers and how they interact are still open.

Small

Small team, real ownership

No layers between you and the work. People here own entire tiers, not tickets.

Honest

We test against the frontier

We benchmark against frontier models and are upfront, internally and externally, about where we're still behind.
