Human Baseliner for Open-Ended ML Research Tasks

## Overview

We are hiring experienced machine learning engineers and researchers to serve as **human baseliners** for evaluations of open-ended machine learning research tasks. These evaluations measure how well AI agents perform on realistic AI R&D problems. To interpret agent performance, we also need strong human reference points: skilled practitioners attempting the same tasks under the same time and compute constraints. As a baseliner, you will complete self-contained ML research tasks in a sandboxed environment, working independently with your preferred tools and workflow. Your performance will be used as a benchmark against which frontier-model agents are evaluated.

## What You’ll Do

• Attempt open-ended machine learning research tasks under a fixed time and compute budget (work trial)

• Work independently in a sandboxed Linux environment with internet access

• Use your preferred tooling, including IDEs and AI coding assistants such as Cursor, Claude Code, and ChatGPT

• Record your full working session via screen recording

• Complete a short pre-task and post-task questionnaire

• Submit your final work product, screen recording, and completed questionnaires: Post this you will be hired for a longer commitment

## Commitment

• Minimum **20 hours per week if selected**

• More availability is strongly preferred

## Requirements

Candidates must meet **all** of the following:

• **3+ years of machine learning experience**

• Time spent in a PhD program counts toward this requirement

• Undergraduate and master’s experience does not count

• Attended a **top-100 university** or worked at **FAANG or a comparable company**

• Experience with at least one major ML framework such as **PyTorch, JAX, or TensorFlow**

• Deep, hands-on expertise in at least one of the focus areas below:

• Pretraining under tight data and compute budgets

• PPO, reward shaping, custom `gym` / `gymnasium` environments, and throughput tuning

• Full fine-tuning, LoRA, QLoRA, DPO, RLHF, RLAIF, and distillation

• Large-scale corpus filtering, deduplication, subsampling, and benchmark contamination avoidance

• Architecture design under strict parameter-count or size constraints

• Modifying pretrained architectures, including attention patterns, pooling heads, or training objectives

• Contrastive training for embedding or retrieval models

• Generative vision or video modeling

• Multilingual or low-resource language experience

• Image or video data pipelines at scale

• Experience balancing competing model objectives such as safety and capability

• Prior work as an ML evaluator, red-teamer, or baseliner

## Required Domain Expertise

Candidates must have strong practical experience in **at least one** of the following:

• **Pretraining**: training transformer language models from scratch

• **Reinforcement learning**: training agents in custom or existing environments

• **Post-training**: fine-tuning and aligning LLMs

• **Dataset curation**: building and cleaning large text corpora for LLM training

• **Model architecture**: designing and modifying neural network architectures

## Logistics (work trial requirements)

• One baseline attempt per contractor per task

• Each task may only be attempted once by a given contractor

• All work is confidential and covered by NDA

• Compute and environment are provided; no personal GPU is required
