ABOUT PROXY FOODS

Proxy Foods is an advanced AI-powered product development and recipe formulation platform trusted by leading R&D teams to create, reformulate, and optimize food & beverage products at scale and in record time. 

We help food and beverage companies move from idea to viable formulation faster by unifying fragmented R&D data: ingredients, specs, cost, nutrition, processing constraints, and compliance. As a result, teams launch new products with fewer failed trials, reformulate faster based on consumer feedback and margin pressure, and stay ahead on trends and regulatory requirements.

• Support the development and maintenance of ETL/ELT pipelines across APIs, databases, files, and external data sources 
• Clean, normalize, validate, and structure datasets related to ingredients, specifications, nutrition, costs, and compliance 
• Write SQL and Python code to transform data and improve data quality 
• Help maintain data models and storage layers used for analytics, reporting, and product features 
• Work closely with product, engineering, and food science teams to understand data needs and business context 
• Monitor pipeline performance, investigate issues, and help improve reliability and observability 
• Learn and apply AI/LLM-assisted workflows where appropriate for data extraction, normalization, enrichment, and structuring tasks under clear guidance and validation practices 
• Document data flows, transformations, and operational processes clearly and consistently

Nice to have: 

• Exposure to cloud data platforms such as Azure
