Job Description

As a Senior Interactive Systems Designer, you will help design and document the interactive systems behind LEGO System A/S' smart play experiences, working closely with designers, engineers, and a range of project teams to ensure LEGO System A/S' play systems are coherent, well-understood, and effective across many contexts.

Core Responsibilities

In this role, you will:

• Design and iterate on interactive play systems, driven by a strong user-experience attitude.
• Produce clear, high-quality design documentation that helps teams across LEGO understand and build on LEGO System A/S' interactive play systems.
• Prototype play mechanics, behaviors, and small interactive systems across a variety of tools and environments to test and validate ideas.
• Apply systems thinking to connect play ideas, mechanics, and technology into coherent, scalable experiences.
• Explore procedural and computational approaches to play, finding new ways to create rich, dynamic interactions.
• Partner closely with engineers, designers, and stakeholders, acting as a bridge between fields to move ideas from concept to reality.
• Communicate design intent, trade-offs, and decisions proactively, keeping collaborating teams aligned and informed.
• Provide creative and technical governance across assets and system features, with foundational context in audio technology, synthesis, and physics.
• Contribute to a culture of iteration, curiosity, and hands-on experimentation across the team.

• A strong, iterative design process driven by user experience and playtesting.
• Hands-on programming and prototyping skills, demonstrated through a portfolio of small behavior-driven prototypes built across a range of tools and environments (e.g., Unity, Unreal, web, microcontrollers, or node-based tools).
• Some experience working with audio technology, including embedded hardware, sound synthesis, or other areas related to procedural audio and/or physical audio products.
• Experience with procedural or computational approaches to design (e.g., generative systems, rule-based behaviors).
• Excellent written communication skills, with a track record of producing clear, high-quality design documentation.
• A proactive, collaborative approach, comfortable bridging design, engineering, and interested party perspectives.
• A passion for play, and for crafting experiences that delight kids and families.

Nice to have:

• Experience designing for connected or physical-digital play.
• Familiarity with game engines, node-based authoring tools, or live-authoring environments.
