About kaiko

kaiko.ai is building a next-generation agentic clinical AI assistant that helps clinicians reason across patient data, guidelines, and diagnostics.

Healthcare decisions are rarely made by a single person or from a single data source. kaiko’s assistant maintains longitudinal patient context across encounters, clinicians, and institutions, enabling collaboration, second opinions, and complex diagnostic workflows. The system is designed to operate safely in real clinical environments, with human oversight, auditability, and regulatory alignment at its core.

Our assistant core supports broadly applicable clinical tasks such as patient data navigation, guideline interaction, multimodal interaction (chat and voice), and care coordination. On top of this foundation, we are developing specialized diagnostic agents in areas such as oncology, radiology, and pathology.

We build in close collaboration with leading hospitals and research centers, including the Netherlands Cancer Institute (NKI). kaiko is a well-funded company with a growing international team, operating from Zurich and Amsterdam.

About the role

We are looking for a working student who is excited to contribute to building high-performance AI models in the medical field.

You'll be responsible for helping us build trustworthy, high-quality datasets that serve as the foundation for training and evaluating medical AI systems. Your work will directly impact the development and validation of large language models (LLMs) designed to understand and support clinical decision-making. You will work closely with medical professionals, AI engineers, and data engineers.

You will be based in the Netherlands with the expectation to work remotely after the onboarding stage. The hourly rate for this role is set to EUR 20 gross per hour.

Some areas of responsibility

If you are a Dutch-speaking medical student with a strong attention to detail, are excited about working hands-on with real clinical texts to improve AI models and want to help build safe and reliable technology for the healthcare system, we think you will love this job.
