About kaiko 

Delivering high quality cancer care is complex; specialists form a view of each patient's condition by reasoning across different data - CT scans, genomics context, treatment history and clinical notes. 

Current AI are powerful within domains but fall short when it comes to reasoning across data or domain areas. kaiko.w, our AI assistant for oncology, aims to equip every clinician with a full understanding of their patients, helping them to reason across data as they assess each case. 

We’re building this in close collaboration with the Netherlands Cancer Institute (NKI) and a growing network of hospitals and research centers. We’ve raised significant long-term funding and have nearly doubled our team over the past year. We’re now 100+ people representing 25 nationalities, based across our offices in Zurich and Amsterdam. 

About the role

This is a hands-on leadership role. You’ll own the end-to-end marketing foundation: clinical messaging and positioning (turning it into usable assets), awareness-building through campaigns and content, and organizing the team, so that marketing execution becomes reliable and scalable. You’ll work closely with our founders, product, sales/commercial, research, and clinical partners.
