Senior Python Engineer

About

Windsor.ai was founded in 2017 in Zürich, Switzerland. We connect data from 300+ sources (Facebook Ads, Google Ads, HubSpot, Salesforce, TikTok) to 30+ destinations (Looker Studio, Google Sheets, BigQuery, Snowflake, and LLMs like ChatGPT and Claude). Our customers include Puma, Audi, UBS, Asics and many more. We are building a platform that makes it easy to connect any data source to any destination, solving the problem of fragmented data tools.
