Job Title: Member of Technical Staff, Realm Lab (frontier AI research)

Job Type: Full time

Location: Remote

The Role

We're hiring a Member of Technical Staff (MTS) to join Realm Lab and drive research initiatives focused on evaluating and improving frontier AI systems.

This is a hands-on technical role at the intersection of machine learning, data research, and evaluation engineering. You'll work closely with researchers and domain experts to develop benchmarks, reinforcement learning environments, and high-quality datasets that advance model capabilities and performance.

What You'll Do

1. Own research and evaluation initiatives end-to-end, from task design and dataset development to benchmark validation and performance analysis.
2. Design and validate capability evaluations, RL environments, and benchmark suites for computer use, agentic workflows, and emerging model capabilities.
3. Develop high-quality datasets, task specifications, evaluation rubrics, and methodologies to improve post-training data quality and model assessment.
4. Analyze model behavior through failure analysis, error taxonomies, and capability gap identification to inform research directions.
5. Collaborate with researchers and domain experts to design experiments, calibrate evaluation quality, and improve model performance.
6. Build reproducible evaluation pipelines and feedback loops to support iterative model development.
7. Contribute to benchmarks, research papers, technical reports, and open research artifacts.

What We're Looking For

1. Strong technical background in computer science, machine learning, AI, or a related field.
2. Hands-on experience designing ML evaluations, benchmark suites, research datasets, or experimental frameworks.
3. Proficiency in Python and experience building data pipelines, evaluation tools, or ML research infrastructure.
4. Understanding of LLMs, foundation models, post-training techniques, and evaluation methodologies.
5. Ability to translate complex real-world workflows into structured tasks, measurable criteria, and research experiments.
6. Strong analytical skills in model failure analysis, experimental design, and evaluation quality.
7. Ability to work independently and collaborate effectively with researchers, engineers, and domain experts.

Preferred Qualifications

1. Experience with reinforcement learning environments, reward modeling, simulators, or feedback-driven training systems.
2. Experience evaluating computer use agents, tool use, browser automation, or multi-step agentic workflows.
3. Familiarity with multimodal reasoning, long-context evaluation, instruction following, or deep research benchmarks.
4. Experience with human-in-the-loop evaluations, expert-generated datasets, or post-training data.
5. Contributions to AI research publications, open-source benchmarks, or evaluation frameworks.
