You’ll be part of a small, experienced team helping to evolve and scale a stable product used worldwide. This is a great role if you enjoy clean architecture, smart problem-solving, and bringing meaningful ideas to the table.

• Are product-minded — you care about the why, not just the what
• Are self-driven and enjoy collaborating in small, async, distributed teams
• Want the chance to grow into more responsibility
• Curious about 3D tech and AI (you don’t need to be an expert — just open)
• Frontend: Angular
• Backend: C#, .NET Core, Web API, Entity Framework
• Cloud: Azure (Functions, VMs, App Services, Monitoring, Storage)
• Database: SQL
• Bonus: Python & C++ (used in 3D pipeline; nice to have but not required)
• Strong problem-solving skills and passion for AI-driven automation
• Comfortable in a fast-paced startup with a problem-solving, AI-first approach.

Why Join Our Team?
