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
You will create high-quality, SWE-bench-style benchmark tasks from real-world software repositories, and build the pipelines and tooling that make task creation faster, more reliable, and more scalable. This is a dual-mandate role: roughly half hands-on task authoring and review, and half engineering the automation that the whole team depends on.





Key responsibilities
Evaluate real-world software repositories for reproducibility, test quality and suitability for benchmark task development.
Understand unfamiliar architectures, dependencies and services, and establish reliable local or containerized execution environments.
Identify self-contained bugs and feature changes from issues, pull requests, commits and repository history.
Construct complete benchmark tasks from selected bugs and feature changes, including the task setup, specification, tests and containerized execution environment.
Write exact, implementation-neutral task specifications that define the expected behavior without revealing the solution.
Create and review tests that measure observable behavior, cover important edge cases and allow valid alternative implementations.
Verify that the original revision demonstrates the expected failure, the reference solution passes and
