Job Description

Just imagine concept designers moving from idea to visualization with less friction because of tools you've built. Then make it real.

About the role

As our Senior Software Engineer (C#/Typescript/AWS), you'll focus on accelerating how concept designers work by embedding AI into their visualization workflow. You'll design and build tools that are genuinely useful, balancing the possibilities of AI image generation with the practical needs of the people using them. This is an opportunity to bridge creative and technical worlds, helping shape products that support designers in their everyday work while building a strong engineering foundation for the future.

Required Qualifications

• Built full stack applications using modern frontend and backend technologies, ideally React and .NET (or similar)
• Integrated third-party APIs and services, including AI or machine learning models, into production systems
• Designed software architecture and system solutions using established engineering practices
• Delivered results within cross-functional product teams alongside designers and product managers
• Led complex initiatives from ambiguity through to a working product
• Partnered with diverse technical and non-technical stakeholders to communicate technical decisions and trade-offs

Preferred Qualifications

• Applied LLM APIs such as OpenAI, Anthropic, or similar within user-facing products
• Created tooling or internal platforms used by non-technical audiences
• Shipped maintainable products with a focus on practical outcomes and long-term sustainability
• Applied UX thinking when designing tools and user experiences

What you'll build

• AI-powered tools that help concept designers move more quickly from idea to visualization
• Solutions that connect rapidly evolving AI capabilities with real creative workflows
• A strong technical foundation that supports future development without sacrificing engineering quality
• An MVP that can be tested and refined through direct feedback from concept designers
• Products that become a trusted part of designers' day-to-day process

If you've worked in a role where you shipped full stack features to production, integrated external APIs, and helped turn unclear ideas into working products, you'll feel at home here. What matters most is your ability to combine strong engineering fundamentals with practical product thinking and a clear focus on user needs.

Life on the team

You'll join the LEGO Designer Technology team, where engineering and creative practice come together to build AI-powered tools for concept designers. We work closely with designers and product managers, creating a short feedback loop between what we build and how it's used. Our team keeps things simple, with daily stand-ups and regular demo sessions to stay connected. We value people who take ownership, work independently on complex problems, communicate clearly, and bring ideas forward while supporting one another. You'll gain hands-on experience with applied AI in an environment that values craft, thoughtful decision-making, and learning together.

What success looks like

Success means becoming a trusted partner to the design community while helping translate creative needs into practical software solutions. You'll master the challenge of connecting AI technology with real-world design workflows and help shape the direction of products in an exploratory environment. Over the next 12 to 18 months, you'll work closely with engineers, a product manager, and designers to influence what gets built and where the team's work goes next.
