Senior Software Engineer (C#/Typescript/AWS) at LEGO Group in Billund, Denmark. This role sits on the Designer Technology team and operates in a hybrid environment to accelerate concept designers' workflows by embedding AI into visualization tools. You will design and build practical, maintainable tools that balance AI-powered image generation with the real needs of designers, bridging creative and technical disciplines to support everyday work while strengthening our engineering fundamentals.

Responsibilities include building full-stack features using modern frontend and backend technologies (e.g., React and .NET or equivalent), integrating third-party APIs and AI/ML models into production systems, and designing software architecture in collaboration with cross-functional teams of designers and product managers. You will lead complex initiatives from ambiguity to working products and communicate technical decisions and trade-offs to diverse stakeholders.

Preferred qualifications include applying large language model APIs (OpenAI, Anthropic, etc.) in user-facing products, creating tooling used by non-technical audiences, delivering maintainable products with practical outcomes, and applying UX thinking to tool design.

What you will build: - AI-powered tools that help concept designers move from idea to visualization - Solutions that connect evolving AI capabilities with creative workflows - A strong technical foundation for future development - An MVP that can be tested and refined with direct feedback from concept designers - Products that become trusted parts of design
