About kaiko

In cancer care, treatment decisions can take many days—but patients don’t have that time. One of the reasons for delays? Cancer patients' data is scattered across many places: doctor’s notes, medical imagery, genomics data. At kaiko, we are developing AI foundational models to bring this data together and integrate it into clinical workflows, enabling doctors to make faster, more effective treatments decisions.

We also collaborate closely with the leading Dutch cancer research institute (NKI) on multiple AI research projects and a joint clinical validation initiative. In 2025, we plan on expanding our partnerships to even more hospitals.

We raised significant long-term funding and have offices in Zurich and Amsterdam. Over the past year, our team has nearly doubled in size, now comprising 80+ people from 25 countries and we just got recognized as a Rising Innovator at the GenAI conference

About the role

You'll contribute to developing user-facing applications that streamline cancer care, giving clinicians seamless access to critical data. Your work will directly support how doctors interact with AI-driven insights, leading to faster and more accurate treatment decisions.

You will be based in The Netherlands or Switzerland, with the expectation of spending at least 50% of your time at the office.

Some areas of responsibility

• Develop and enhance reusable components and interfaces for medical applications. Examples can include medical image viewers, data reporting interfaces for clinicians or software performance monitoring UIs;

• Participate in technical discussions and contribute to design and delivery of new features;

• Help maintain the development infrastructure needed for projects, including GitHub actions, Docker files, and release deployments;

• Collaborate closely with UX Designers to understand design requirements and user experience goals;

• Translate Figma designs into high quality front-end code, ensuring pixel-perfect implementation;

• Collaborate with the regulatory team for the continuous development and releases of medical software devices;

• Rapidly prototype user interfaces, allowing for quick iteration and feedback during the design and development process;

• Write well tested, reusable and easy to maintain code.
