About the role
The Role
We're hiring a Founding Scientist — a founding executive who will own the hardest open problems on Multifactor's roadmap and carry the answers all the way into production.
This is not a research-lab sinecure, and it's not a publishing post with a fancy title. The problems we need solved have no existing solutions in industry or academia. You'll work directly with our founder & CEO — whose decade of cryptographic research and patents underpin the company — to set the research agenda, then prototype, build, and ship it yourself. The loop between "conjecture" and "in production" here is measured in days, not quarters.
Few roles offer this much leverage: the systems you invent will define how millions of humans safely delegate their digital identities to AI agents.
Problems You'll Own
A representative sample of what's on the whiteboard. None of these has a known answer yet:
- Fine-grained delegated authorization for AI agents. Build a policy model expressive enough to capture real human intent — "my agent may use my LinkedIn to post on my behalf, but never reply to comments," or "it may place trades under $1,000, but only in these sectors" — and a runtime that enforces those policies against a live, authenticated session, detecting and stopping violating actions before they complete. Formal policy semantics meet real-time semantic analysis of agent behavior.
- Natural-language semantic auditing. Give users provable, human-readable answers to "what exactly did this agent do with my account?" — at scale, across arbitrary websites.
- High-precision authentication-message understanding. Identify and route one-time codes and verification links from email and SMS streams with near-zero false positives, strict privacy guarantees, and nothing else ever read.
- Durable session continuity. Keep authenticated sessions warm, healthy, and instantly resumable across cloud and local environments — so neither users nor their agents ever wait at a login wall — and make it work reliably across the chaotic diversity of session-management behavior on the modern web.
