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:

Own the entire technical system that turns raw institutional data into lab-grade product - across three pillars: the data-to-delivery pipeline, the task-building infrastructure,



and the RL environments that run those tasks - and lead the engineering team building all three.

The three pillars you own

Pillar 1 - Raw data to delivery-ready product.

The ingestion pipelines that pull data from many enterprise sources, the PII-removal and cleaning layer, and the conversion and delivery of finished, machine-trainable product to labs and to other RL-environment companies. This is the business today; it has to be reliable, scalable, and privacy-safe.

Pillar 2 - Task-building infrastructure.

Create, or help create and assemble, the infrastructure required to build tasks at scale — the mining/extraction pipelines, verifier and grader tooling, packaging, and the harness that turns raw substrate into validated tasks across verticals (coding first, then company ops, medical).

Pillar 3 - Environments.

Stitch together the RL environments and run these tasks on them — reproducible sandboxes, the execution and orchestration layer, and the eval/rollo
