The Role

OpenTrain is seeking a Nutrition and Culinary AI Evaluation Expert to help fine-tune large language models with nutrition, dietetics, culinary operations, and menu-engineering logic. The work combines professional food and nutrition judgment with deterministic spreadsheet logic and structured quality review.

This is a worldwide, remote contractor opportunity conducted in English, with a part-time commitment of 20 or more hours per week.

• Review validation dropdowns and deterministic spreadsheet formulas across meal planners and kitchen dashboards.
• Evaluate AI-generated outputs for alignment with dietetic, culinary, and menu-engineering practices.
• Apply checks for food-cost percentage targets, dietary restrictions, and allergen exclusions.

Required Qualifications

Applicants should bring substantial practical experience in nutrition, dietetics, culinary operations, menu planning, or food-service operations. A bachelor's degree or equivalent practical experience is expected.

You must be able to apply nutrition and recipe rules precisely, explain your judgment clearly, and work with structured spreadsheet formulas and validation systems.

• At least five years of professional experience in nutrition, dietetics, culinary operations, menu planning, or food-service operations.
• Ability to calculate and validate calorie and macronutrient targets using 4/4/9 kcal-per-gram logic.
• Practical skill with per-serving and per-batch recipe scaling, ingredient costing, and grocery budget rollups.
• Strong judgment when handling dietary restrictions, allergen exclusions, and food-cost percentage targets.
• Ability to translate nutrition and recipe rules into deterministic spreadsheet formulas and validation structures.
• Strong concise professional writing and analytical judgment.
• Reliable desktop or laptop and high-speed internet connection for remote work.

Helpful Background

Experience in AI evaluation, data annotation, content review, quality assurance, or another analytical role can be useful when reviewing and refining AI-generated outputs. The central requirement is the ability to combine specialized nutrition and culinary knowledge with careful, repeatable evaluation.
