Lead Engineer, Mobile Games

Overview

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.

• 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

• 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

• 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

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.

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:

• Extensive experience 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/Type Script and Web related experience
• Performance testing, security, or compliance experience in mobile environments
