Sr Software Engineer, Graphics in London

LEGO Digital Play will bring the LEGO brand into digital entertainment in new, innovative, and wholly-owned ways. Our mission is to ensure the LEGO Brand remains as powerfully a part of children’s lives in the coming decades as it has ever been. We aim to reach every kid on the planet, their parents, and adult fans of LEGO—and provide them with meaningful, magical, and playful new experiences.

Central Technology is the engineering heart of LEGO Digital Play, a venture within the LEGO ecosystem dedicated to pioneering creative and joyful digital experiences. Our teams build the foundational platforms, tools, and capabilities that power LEGO's digital future. We work at the intersection of play, applied AI, and developer tooling to bring the LEGO brand to a new generation of digital builders. It's a rare opportunity to shape something from the ground up within one of the world's most loved brands. Our culture is open, collaborative, intellectually rigorous, and creatively vibrant.

This is a newly created individual contributor role based in London, reporting to the Director of Digital Art and Avatars.

Key Responsibilities

• Design and build graphics technology and tooling that puts high-quality visual results within reach of game development teams.
• Choose and implement rendering techniques that sustain visual quality and performance at extreme scene scale and density, scaling gracefully across all classes of mobile device and beyond.
• Contribute to the graphics side of benchmark and regression suites, ensuring the core systems' scale remains renderable within the frame budget.
• Ground technical direction in evidence, presenting and sharing findings that inform teams and the work that builds on them.
• Profile, debug and optimise across CPU and GPU to ensure the technology performs well in the hands of its users.
• Contribute across the core systems and tooling that surround the renderer, in close partnership with senior domain specialists and tools engineering.
• Embed brand integrity, reliability and safety-by-design principles into the technology from the ground up.

Required Qualifications

• Degree in Computer Science, Software Engineering, STEM field or equivalent practical experience.
• Deep expertise in real-time rendering, including evaluating, selecting and implementing techniques that hold up at extreme scene scale and density across the different tiers of mobile hardware and other platforms.
• Background in games with one or more shipped high quality titles.
• Expert C/C++ skills with experience working in large codebases, and the ability to remain hands-on in implementation, debugging, profiling and shipping.
• Strong shader programming skills.
• Experience developing with a major game engine, commercial or proprietary, and the willingness to work with the major commercial engines.
• A rigorous, evidence-driven approach to performance work, from profiling and benchmarking through to measurement and analysis other engineers can rely on.
• Fluency with modern AI tooling across development and the work around it, using it to move faster while retaining the judgement to catch its failures and stand behind the quality of what ships.
• Strong communication and collaboration skills across technical and non-technical audiences, with the ability to present findings and trade-offs clearly.
• Comfort operating with ambiguity in an early-stage environment, with sound judgement and integrity.

Preferred Qualifications

• Experience building or significantly contributing to rendering engine internals.
• Console development and cross-platform rendering experience.
• Publications, conference talks or open source contributions in rendering.
