Staff Machine Learning Engineer

The opportunity
We are building the next generation of AI-driven game experiences generative world models neural rendering and multi-modal understanding that turn images text and 3D primitives into interactive worlds. As our Staff Machine Learning Engineer you will be a core technical leader bringing state-of-the-art computer vision and multi-modal models transformers diffusion networks vision-language models (VLMs) and JEPA-style architectures from research into robust production-grade systems.

This is a deeply hands-on high-impact role. You will help define the modeling anddeployment strategy drive architectural decisions across the ML stack and mentor a teamof senior and mid-level engineers. Your work will directly shape the quality capability andperformance of AI features experienced by billions of players across cloud server andon-device targets.

What youll be doing

Technical Leadership

• Help set the technical vision and roadmap for computer vision and multi-modal AI models spanning transformers diffusion models vision-language models and JEPA-style generative architectures.
• Drive design and implementation of models for image and video understanding generation segmentation detection and dense prediction as well as multi-modal reasoning over images text and 3D inputs.
• Make sound decisions on model architecture training strategy data pipelines and evaluation balancing quality capability latency and cost across deployment targets.
• Own the path from research prototype to production: training fine-tuning distillation export and serving with deployment spanning cloud GPUs through to efficient on-device inference where the product requires it.

Architecture & Research Translation

• Collaborate directly with research scientists to translate novel CV and multi-modal model architectures into deployable well-engineered implementations.
• Design scalable systems for multi-modal inference that process diverse inputs images
• video text primitives and metadata and produce rich outputs from semantic
• predictions to pixel-level generation.
• Track and rapidly adopt breakthroughs across the field: vision-language pretraining and
• alignment efficient diffusion (e.g. consistency models flow matching) efficient attention
• e.g. FlashAttention linear-attention variants) and tokenization/representation learning
• for vision.
• Where latency or device constraints demand it apply compression quantization pruning and knowledge distillation and work with appropriate runtimes (e.g. TensorRT ONNX Runtime CoreML TFLite) to meet performance budgets.
• Team & Cross-Functional Leadership
• Lead and mentor a team of ML engineers; define engineering best practices code review standards and rigorous benchmarking and evaluation methodology.
• Partner with research platform engineers product managers and runtime teams to align ML capabilities with product roadmaps and target-platform constraints.
• Champion a culture of measurement: define KPIs for model quality accuracy latency memory and cost and ensure the team tracks them rigorously.

What were looking for

• 6 years in ML engineering with significant depth in computer vision and/or multi-modal modeling.
• Proven production experience with transformer-based and diffusion-based vision models (e.g. ViT CLIP/SigLIP-style encoders Stable Diffusion DETR/SAM-style architectures)
• Strong command of the full model lifecycle: data curation training and fine-tuning evaluation and serving at scale.
• Familiarity with efficient attention diffusion samplers multi-modal fusion and vision-language alignment techniques.
• Strong Python and modern deep-learning tooling (PyTorch); solid software
• engineering fundamentals.
• Track record of technical leadership: setting direction influencing cross-functional partners and growing engineers.

You might also have

• Experience with world-model video-generation or neural rendering pipelines (NeRF
• 3DGS or similar).
• Experience deploying models to constrained or on-device targets including quantization
• INT8/INT4/FP16) pruning distillation and runtimes such as CoreML TFLite ONNX
• Familiarity with mobile SoC accelerators (Apple Neural Engine Qualcomm Hexagon/AdrenoARM Mali) or compiler stacks such as MLIR TVM or XLA.
• Contributions to open-source ML frameworks or peer-reviewed CV/ML research publications.
• Background in real-time graphics or game engine pipelines (Metal Vulkan OpenGL ES).
