Lead Engineer, Mobile Games
We are looking for a hands-on Lead Engineer, Mobile Games to help shape and evolve our technical roadmap through the development of prototypes, reference implementations and vertical slices - playable game experiences that validate and stress-test our platform under real-world conditions, all while exploring new ways of play for the LEGO Brand in action
You will lead engineering for the team responsible for building and evolving these experiences, with an integration-first mindset, and the objective to create fast feedback loops resulting in outstanding quality through iteration, covering SDKs, backend services, user interfaces, analytics, security, CI/CD pipelines, performance systems, and more
The role sits at the intersection of game development and platform engineering, and requires a blend of strong architectural thinking, deep mobile experience, a solid understanding of game-as-a-service models and backend-heavy systems, multiplayer models, gameplay systems, and a mature sense of what-good-looks like technically and creatively
Key Responsibilities
Platform-Driven Game Development
Lead the development of mobile game experiences that validate and evolve our platform efforts by architecting applications that function as both creative and technical prototypes, as well as a validation layer for platform components
Ensure both functional and non-functional requirements (performance, scalability, security, compliance) are continuously tested
Evolve game and technical direction in alignment with platform roadmaps and strategic priorities
Technical Leadership & Engineering Excellence
Define scalable, long-term architecture suitable for live-operated mobile games, with high-quality, maintainable code designed to live and evolve for years
Embed strong CI/CD practices, automated testing, and fast deployment cycles as standard ways of working
Ensure Design systems and workflows that integrate effectively with AI-assisted development and agentic AI tools
Cross-Functional Collaboration
Establish strong collaboration across engineering, product, design, production, analytics, and business teams
Position your team as tip of the spear for quality, productivity, and creative feedback for our broader platform initiative
Communicate technical direction clearly to both technical and non-technical stakeholders
Team Leadership & Culture
You will build and lead a high-performing engineering team. Success in this role requires leading by context and empowerment. You foster an environment of ownership, constructive debate, and shared accountability
What We’re Looking For
You are a product-oriented technical leader who understands that technology is a means to create meaningful player experiences. You are comfortable operating in exploratory environments where iteration, learning, and feedback are essential
Must-have experience:
10+ years working with commercial game engines (expert in Unity, Unreal experience) with expert level proficiency in C#, C++
Proven delivery of game-as-a-service or backend-intensive architectures
Strong understanding of various multiplayer models and familiarity with contemporary gameplay architectures such as entity component systems
Versed and experienced integrating third-party SDKs (analytics, monetization, attribution, etc.) and related best practices
Experience leading engineering teams and mentoring developers, shipping games and technical products from concept through launch
Practical experience using AI-assisted development workflows
Valuable additional experience:
Building and supporting technical products for internal consumption
Experience contributing to shared game or publishing platforms
Backend/cloud infrastructure knowledge
JavaScript/TypeScript and Web related experience
Performance testing, security, or compliance experience in mobile environments
