Data Scientist - AI Safety

About Eleven Labs

Eleven Labs is an AI research and product company transforming how we interact with technology.

We launched in January 2023 with the first human‑like AI voice model. Today, we serve millions of users and thousands of businesses - from fast‑growing startups to large enterprises like Deutsche Telekom and Meta. Our investors are some of the world's most prominent, including Andreessen Horowitz, ICONIQ Growth and Sequoia. We've raised $781M in funding and our last valuation was $11B - multiples of 11, always.
We have expanded from voice into three main platforms:

• Eleven Agents enables businesses to deliver seamless and intelligent customer experiences, with the integrations, testing, monitoring, and reliability necessary to deploy voice and chat agents at scale.

• Eleven Creative empowers creators and marketers to generate and edit speech, music, image, and video across 70+ languages.

• ElevenAPI gives developers access to our leading AI audio foundational models.

Everything we do is the result of the creativity and commitment of our team - builders doing the best work of their lives. We are researchers, engineers, and operators. IOI medalists and ex‑founders. If you want to work hard and create lasting positive impact, we want to hear from you.

• High‑velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy.

• Impact not job titles: We don’t have job titles. Instead, it’s about the impact you have. No task is above or beneath you.

• AI first: We use AI to move faster with higher‑quality results. We do this across the whole company—from engineering to growth to operations.

• Excellence everywhere: Everything we do should match the quality of our AI models.

• Global team: We prioritize your talent, not your location.

• Innovative culture: You’ll be part of a generational opportunity to define the trajectory of AI, surrounded by a team pushing the boundaries of what’s possible.

• Growth paths: Joining Eleven Labs means joining a dynamic team with countless opportunities to drive impact - beyond your immediate role and responsibilities.

  If you’re not located near one of our main hubs, we offer a monthly co‑working stipend.

We're looking for a Data Scientist to take ownership of the datasets and evaluation workflows that underpin our AI Safety work. You'll 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'll work closely with safety researchers, engineers, and policy specialists to translate complex safety requirements into practical data and evaluation systems - starting hands‑on with collection, analysis, and labelling, then building the methodologies, contributor networks, and quality standards that let this work scale.

• Own safety datasets end‑to‑end: collection, cleaning, labelling, quality control, versioning, and readiness for training and evaluating.

• 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.

• Experience as a Data Scientist, or similar, working with real‑world datasets and ML models.

• Strong grasp of what…
