about us
? www.wincan.com Position Overview: You will join a team developing web-based tools for reviewing and analyzing sewer inspection data. Your primary focus will be interactive frontend visualization of individual 3D scans, inspection video, annotations, and results provided by AI-based processing services. You will also develop selected backend APIs and integrations using C# and ASP.
NET Core. This is a frontend-focused full stack role, with an approximate balance of 70% frontend and 30% backend. The position does not involve developing or training AI models. Instead, you will integrate processing results into the product and turn them into intuitive tools for end users. Product Description: WinCan Web is an established cloud platform that supports sewer inspection companies, municipalities, and infrastructure management organizations in reviewing inspection data and assessing underground infrastructure. It is integrated with WinCan AI, a collection of AWS-based processing services. Depending on the available project data and selected workflow, these services can reconstruct 3D models from video, identify structural components, and detect structural defects. Processing is performed asynchronously, while WinCan Web provides user-facing tools for accessing and understanding the results. Inspection video, annotations, detected objects, point clouds,



and 3D models are presented in a synchronized browser-based environment, helping trained professionals review inspections more efficiently and make better-informed decisions. The product has evolved over many years and continues to be actively maintained, modernized, and extended. The developer joining the team will focus on the parts of WinCan Web directly integrated with WinCan AI, including frontend visualization, backend APIs, processing workflows, and related data integrations.
