Responsibilities
We are seeking an Algorithm Research Scientist to join the Applied Machine Learning – Machine Learning Systems (AML-MLSys) team. The team focuses on designing and scaling machine learning systems that bring state-of-the-art algorithms into real-world applications. In this role, you will drive the conception, design, and validation of advanced machine learning algorithms, with a strong emphasis on efficiency, quality, automation, and system awareness. You will work end-to-end, from problem formulation and theoretical reasoning to proof-of-concept, experimentation, and system-level design—bridging research and product in close collaboration with engineering and infrastructure teams. In addition to research contributions, this role requires strong engineering rigor: you are expected to write production-quality code, contribute to shared codebases, and participate in code reviews and long-term maintenance of research and ML system components. Responsibilities: - Propose and design novel or state-of-the-art (SOTA) machine learning algorithms, focusing on efficiency, scalability, and automation. - Formulate research problems clearly, provide theoretical insights or empirical justification, and validate ideas through POCs and controlled experiments. - Design and execute large-scale experiments to evaluate algorithmic trade-offs and system implications. - Collaborate closely with engineers to ensure algorithms are system-aware, scalable, and production-impactful. - Apply product thinking to research by prioritizing impact, robustness, and real-world ML system constraints. - Contribute to system design and architectural decisions related to ML models, training pipelines, and evaluation frameworks. - Develop and maintain high-quality research and system code, following best practices in code quality, testing, documentation, and collaborative development (e.g., code reviews, shared repositories). - Document and communicate research findings clearly to both research and engineering audiences.
Qualifications
Minimum Qualifications: - Bachelor’s degree or above in Machine Learning, Computer Vision, NLP, or a related field (or equivalent research experience). - Strong background in machine learning algorithms and deep learning. - Proven ability to independently solve complex algorithmic and research problems. - Experience designing, running, and analyzing experiments at scale. - Strong communication and cross-functional collaboration skills. - Strong engineering skills, including experience writing clean, maintainable, and production-quality code and contributing to shared or long-lived codebases. Preferred Qualifications: - Publications in conferences or a strong internal research track record. - Demonstrated experience bridging algorithm research and ML systems, including awareness of training efficiency, scalability, and deployment constraints. - Experience working in applied or product-oriented research environments, translating research prototypes into robust, reusable implementations.
