About LH2 AI Labs

Built by second-time founders who have built and sold companies before, LH2 AI Labs is building the post-training infrastructure for frontier AI models.

We bring private, high-quality institutional datasets and vetted domain experts into frontier AI pipelines across verticals such as coding, computer use, agentic workflows, medical, audio, and more.

For AI to keep progressing, it needs high-quality training data drawn from real production use cases. The public web has already been crawled and trained on—there is limited new signal left there. That is where we come in.

Our vision is to create a world where frontier models can access high-quality data on tap, the same way they access compute today.


About the role

Our entire product rests on one promise: raw enterprise data goes in, and what comes out is safe to sell — nothing identifiable, nothing leaked, provably de-identified, with the audit trail to back the claim.



You'll own that promise. You'll build the detection, entity-consistent pseudonymization, vault, and residual-risk gates that convert sensitive enterprise data into a trainable product buyers and regulators can trust.

This is a hands-on founding role and the most trust-critical seat on the team. The difference between a sellable product and a liability is the judgment in this role.

Responsibilities
- Own the de-identification pipeline end to end: sensitive-entity detection → entity-consistent pseudonymization → residual-risk validation → clean export
- Build PII/PHI/secret detection across free text, structured fields, and layout, using and extending tools like Presidio plus custom recognizers
- Design and operate the
vault
: one durable, namespaced surrogate per resolved entity, so the same person maps to the same pseudonym across every system (name, email, employee id, Slack/Jira/Git ids) — without token dri
