Senior Backend Engineer (.NET)

In the BlinkID Verify team, we are building an API for document verification that determines whether the document presented in an image is authentic or not. The product utilizes in-house-developed machine learning (computer vision) models for document analysis as well as additional business logic to check against common fraud vectors. The product is consumed by developers whom we see as important users, while the verification results are utilized by banks, retail, gaming, and other industries in many of their critical user identification flows.
