Data Scientist - AI Safety

We are seeking a Data Scientist to take ownership of the datasets and evaluation workflows that underpin our AI Safety work. You will turn real-world product data into reliable, well-structured datasets for training and evaluating models, and help build the processes and infrastructure to continuously assess how those models perform in production.

This is a hands-on role at the intersection of data science, ML, AI safety, and policy. You will work closely with safety researchers, engineers, and policy specialists to translate complex safety requirements into practical data and evaluation systems.

Responsibilities

• Own safety datasets end-to-end: collection, cleaning, labelling, quality control, versioning, and readiness for training and evaluation.
• Translate safety policy into clear, consistent labelling and evaluation criteria, working closely with policy specialists.
• Design and manage labelling processes, including sourcing, onboarding, and overseeing external contributors to a high quality bar.
• Build evaluation workflows for models in production, using real-world data to track performance and surface issues.
• Develop lightweight Python/SQL pipelines and tooling to make data work faster and reproducible, partnering with ML engineers on what "training-ready" looks like.

Requirements

• Experience as a Data Scientist, or similar, working with real-world datasets and ML models.
• Strong grasp of what makes a good dataset: collection, cleaning, sampling, labelling, quality control, evaluation.
• Comfortable with Python and SQL for analysis and practical data workflows.
• Strong critical thinking and judgement - comfortable with ambiguity and nuance, and able to turn complex guidelines into consistent, scalable decisions.
• Autonomous and a clear communicator, able to work across disciplines (policy, engineering, research) in a fast-moving, still-forming environment.

Benefits

• Innovative culture
• Growth paths
• Learning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend.
• Social travel: We provide an annual discretionary stipend to meet up with colleagues each year.
• Annual company offsite: Each year, we bring the entire team together in a new location.
• Co-working: If you're not located near one of our main hubs, we offer a monthly co-working stipend.
