Careers

Argue with machinesfor a living.

We hire people who enjoy being wrong early. Engineers, lawyers, and designers who would rather find the flaw on Tuesday than explain it on Friday. Small team, high standard, unusually honest meetings.

How we work

Deliberately small, deliberately senior. Every hire reviews real findings in their first week. We write things down, we disagree in the open, and we never ship work we haven't attacked ourselves.

Open roles

New York · Hybrid

Senior Adversarial Engineer

Design the attack passes. You'll work on the layer that argues — contradiction hunting, counterfactual engines, authority verification at scale.

London · Hybrid

Legal Doctrine Lead

Own the doctrine. Translate litigation craft into the instructions 47 agents follow, and keep them honest as the law moves.

Remote

Design Engineer

Build the surface the verdict arrives on. Editorial sensibility, motion craft, and respect for the reader's attention required.

Talk to the opposition before your work meets one.
