Python Machine Learning Engineer

ABOUT THE ROLE There are over 5 billion users using basic applications today such email, notes, tasks, calendar and they’re not AI-native. As Staff Machine Learning Engineer, you own the execution layer of our intelligence, turning research and model capabilities into reliable, scalable production systems.

You will work across the model lifecycle: data, training, evaluation, inference, and deployment. Own the end-to-end ML systems powering our company, from data and training to evaluation, inference, and deployment.

• Build and evolve training and fine-tuning pipelines for large models.
• Build data pipelines and systems for high-quality real-world and synthetic training data.
• Strong understanding of modern large-model training, fine-tuning, evaluation, and inference.
• Strong software engineering and systems fundamentals.
• ML pipelines, training loops, and inference systems are stable, efficient, and maintainable.
• Team members are supported, aligned, and able to deliver high-impact ML work with minimal friction.
• Python
• GPU-based training and inference system

We are a small, high-talent-density, hands-on team. We make decisions quickly, work closely together, and balance speed with engineering fundamentals. it’s an invitation to be part of a team that’s bringing AI to have practical benefits to billions globally.
