Job Description
Want to build the digital play experiences that bring LEGO products to life?
This role helps ensure that strong mobile engineering becomes a foundational capability across our portfolio rather than something solved app by app. By driving architecture, improving development practices, and supporting both modern cross-platform and legacy applications, you’ll give the team the technical strength to move faster and build with confidence. Your work will directly support the broader organization’s ambition to deliver high-quality digital play experiences that children love and families trust.
Responsibilities
Design, architect, develop, and maintain scalable cross-platform mobile applications for LEGO consumers.
Lead technical decisions on app architecture, code structure, and platform strategy to support long-term scalability and maintainability.
Maintain and evolve legacy Unity applications by delivering new features and supporting upcoming LEGO products and experiences.
Partner closely with UI/UX designers to deliver world-class user experiences with high attention to quality, usability, and visual detail.
Ensure high engineering standards across code quality, testing, automation, release processes, and application reliability.
Collaborate with Quality Assurance and Consumer Service teams to identify issues, improve app performance, and enhance customer satisfaction across multiple products.
Mentor and support other engineers on architectural patterns, scalable development practices, and modern cross-platform frameworks and tools.
Requirements
Hands-on production experience with Unity or a similar cross-platform mobile app framework (Flutter, React Native, KMP, etc.).
Strong software engineering fundamentals, including architecture, object-oriented design, testing, debugging, and performance optimization.
Proven experience designing scalable, maintainable application architecture for consumer-facing mobile apps.
Experience working with legacy codebases and modernizing existing applications while maintaining stability and compatibility.
Ability to collaborate effectively across engineering, QA, design, and product teams to deliver high-quality user experiences.
Strong understanding of code quality practices, automated testing, CI/CD, and release processes for mobile applications.
Significant software engineering experience, with substantial experience developing mobile or cross-platform consumer applications.
Applications are reviewed on an ongoing basis. However, please note we do amend or withdraw our jobs and reserve the right to do so at any time, including prior to any advertised closing date. So, if you're interested in this role we encourage you to apply as soon as possible.
