Researcher, Evals

About the role

The New Horizons Evaluations team is reimagining how we measure progress in interactive machine intelligence. As Evaluations Lead, you will design evaluation frameworks that capture not just what models know— but how they reason, remember, and interact over time. You’ll work at the intersection of research, product, and infrastructure to develop metrics, systems, and studies that define what “intelligence” means in the next generation of AI.

Your work will shape how Cartesia builds and evaluates frontier models, ensuring that progress isn’t measured solely by static benchmarks, but by deeper qualities like understanding, naturalness, and adaptability in real-world interaction.

What You Bring

• Experience designing or implementing evaluation frameworks for generative models (audio, text, or multimodal)
• Strong technical and analytical skills, ability to take open-ended research ideas and translate them into production-ready systems
• Creativity in defining novel quantitative metrics for subjective or behavioral qualities
• Excitement for building evaluation systems that bridge research and real-world use
• Curiosity and rigor in equal measure; motivation driven by discovering how to measure meaningful progress in intelligent behavior

Nice-to-Haves

• Understanding of model alignment concepts and evaluation approaches
