Job description

At Anaplan, we are a team of innovators focused on optimizing business decision‑making through our AI‑infused scenario planning and analysis platform. We seek a versatile Principal Data Scientist to work across the full stack of Anaplan AI applications, from model integration and prompt engineering to building intuitive user interfaces.

Responsibilities

• Lead research, design, and implementation of advanced machine learning, deep learning, and time‑series forecasting models to solve complex enterprise business and planning challenges.
• Architect generative AI solutions, focusing on fine‑tuning proprietary and open‑source large language models via transformer architectures for specialized enterprise data tasks.
• Design and integrate conversational AI and autonomous agent workflows to create intuitive experiences that can independently execute complex planning tasks.
• Collaborate with Engineering, Product, and Design teams to transition AI models from prototypes into robust, scalable production systems.
• Serve as a core subject‑matter expert, mentoring cross‑functional teams and driving a culture of technical excellence, rigorous testing, and continuous learning.

Qualifications

• Extensive professional engineering experience in artificial intelligence, machine learning, or related domains.
• Deep technical understanding of transformer architectures, prompt engineering, and conversational AI patterns, with practical experience in autonomous agent frameworks.
• Experience fine‑tuning LLMs (e.g., LoRA, QLoRA, RLHF) for domain‑specific enterprise applications.
• Track record of owning models from concept to production, using strong MLOps and LLMOps practices to ensure scalable, reliable, and monitorable deployments.
• High proficiency in Python and modern software development practices, including rigorous testing, code reviews, and CI/CD pipelines.
• Hands‑on experience in traditional machine learning and deep learning techniques, specifically time‑series forecasting algorithms.

Desirable Skills

• Background in computer science, artificial intelligence, statistics, data science, or a related quantitative field.
• Experience with scalable cloud infrastructure (AWS, GCP, or Azure) and MLOps tools for model training, monitoring, and deployment.
• Experience in forecasting, planning, or analytics applications.
• Familiarity with Anaplan or similar enterprise planning platforms.
• Experience with A/B testing and experimentation frameworks for AI features.
• Contributions to open‑source ML projects or research publications.
