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 recent 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.

The Role
We are looking for an AI Research Engineer — AI Evaluation, Benchmarking & LLM Post-Training to help us build evaluation and training-data systems for frontier AI models and coding agents.
In this role, you will work at the intersection of software engineering, AI evaluation, benchmark design, and post-training.



You will create realistic coding tasks from real repositories, build reproducible evaluation environments, design tests and verifiers, analyse model performance, and improve the quality of data used to train and evaluate AI systems.
This is a strong fit for a research-oriented software engineer with practical experience in coding benchmarks such as SWE-bench, SWE-Bench Pro, DeepSWE, Terminal-Bench, or equivalent repository-based evaluation frameworks.

What You’ll Do
Design realistic coding tasks covering debugging, feature development, refactoring, code review, repository navigation, and test-based problem solving.

Source and structure tasks from repositories, issues, pull requests, commits, diffs, test suites, and customer-provided codebases.

Build reproducible evaluation environments using repositories, Docker containers, dependencies, test harnesses, sandboxes, and code-execution workflows.

Define task instructions, acceptance crit
