The job description
Project Overview
We are sourcing independent LaTeX Specialists to provide their expertise for an AI benchmark evaluation project. As AI models increasingly generate complex long-form content that blends mathematical and technical formatting with creative prose, their quality relies entirely on robust, expert-reviewed training data. The objective of this project is to autonomously evaluate, rewrite, and refine AI-generated text to meet specific stylistic guidelines while ensuring flawless LaTeX rendering and proper markdown formatting.
Project Deliverables & Scope
Operate autonomously to audit, edit, and refine complex AI outputs. Expected deliverables include:
- LaTeX & Math Rendering Correction: Identifying and correcting malformed LaTeX expressions, unclosed environments, and inaccurate mathematical notations within text.
- Stylistic Rewriting & Editing: Rewriting AI-generated text to meet strict stylistic, structural, and creative requirements, ensuring engaging prose, varied sentence structure, and pristine grammar.
- Markdown Formatting: Fixing broken markdown elements, including unclosed code blocks, inaccurate language tags, headers, and list numbering to ensure flawless structural formatting.
- Consistent Rubric Application: Applying complex, multi-part evaluation rubrics consistently across high volumes of tasks to generate clean, reliable data for model training.
- Localization & Standardization: Ensuring all generated text adheres strictly to spelling, grammar, and formatting conventions.
Required Expertise
To successfully fulfill the deliverables of this project, Contractors must possess strong technical formatting capabilities paired with a sharp editorial eye.
Core skillset includes:
- Familiarity with LaTeX syntax, specifically the ability to accurately spot and correct malformed mathematical expressions and technical notations.
- Native or near-native English proficiency with a solid grasp of US spelling, grammar, and formatting conventions.
- A strong background in creative writing, editing, fiction, journalism, copywriting, or similar fields.
- Hands-on experience with Markdown formatting, including the proper structuring of code blocks, headers, and lists.
- A meticulous, detail-oriented approach with the ability to confidently navigate and follow multi-part rubrics across high task volumes.
We offer a pay range of $8-to-$30 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you’ll supply a secure computer and high‑speed internet; company‑sponsored benefits such as health insurance and PTO do not apply.
