Who is Eleos Health?
Today, more people than ever are speaking publicly about their mental health. Whether it's ourselves, our friends and family or even public figures, taking care of your behavioral health is no longer a taboo, it's vital, and it's only human.
Eleos is on a mission to help deliver the world's most effective behavioral care through data, measurement, and personalization. Or simply put, we want to give clinicians the support they need to do the important work only they can do.
What is this opportunity?
We’re looking for a talented and driven Data Science to join our Data Science / Applied AI team in Tel Aviv.
You’ll work alongside senior data scientists and ML engineers on production AI systems that directly impact clinical care.
This is a hands-on role. You’ll contribute to real projects from day one: improving AI-powered services, building evaluation pipelines, working on data quality and processing, and supporting the infrastructure that keeps our systems running reliably at scale. We value people who can operate independently, learn quickly, and deliver quality work in a fast-moving environment.
