Praevi is a startup founded by two experienced entrepreneurs. It's born from the daily frustrations that people in healthcare have with the existing work rostering processes. Poor work-rostering drives up sick-leave and staff turnover while at the same time the demand is rising due to an aging population. Existing solutions don't solve this, so we started Praevi to target this from a different angle.

Vincent van den Tol (technical co-founder, computer science background) is responsible for the product and technology. Léon Janssen (commercial co-founder) leads the relationships with healthcare organizations and commercial growth.

We're now looking for an AI/ML or computer science graduate to join our growing team and improve the personal alignment and flexiblity of automated planning processes. Why you should consider this assignment

Let's face it, everybody want to do something with AI and this is probably not the only assignment you will read. But while most assignments are focused on saving costs, identifying risks or finding new business opportunities, we offer the possibility to have a direct impact on society by helping healthcare organizations, nurses and physicians to keep healthcare accessible.

Dutch healthcare is under strain: demand is growing while staffing falls short. Rostering ("who works when") is critical to using hours efficiently and keep people happy and energized. Instead, it's often a major source of frustration due to inflexibility and lack of autonomy. Many optimization algorithms exist, but we see that a lot of healthcare teams don't use them, or keep a manual process on the side. We believe this is because of:

As a result, qualified staff spend days per month on manual planning, changes require constant back-and-forth, louder voices win, and rules depend entirely on the individual planner — hurting job satisfaction and retention.

Rather than optimizing existing solutions by a few percent, we believe we can have more impact by first making automatic rostering accessible to everyone in healthcare. This requires us to think differently:

We see an opportunity to combine LLMs with proven ML algorithms, modern interfaces, and agent-based execution to implement these requirements.

Our application is already running inside a first hospital in The Netherlands and we are in the process of setting up pilots with more organizations. We have set the groundwork, and your work will contribute to expanding this foundation into our long-term vision of a smart, flexible and user-friendly planning solution.

We currently have an open position to help us improve our AI agents to deal with the questions above, and we are happy to share our ideas if you are interested.

For your assignment you will work in a small but experienced team. You will have freedom to work how and where you like, you can (optionally) participate in related developments if that helps your assignment, and work with very direct lines and regular face-to-face moments. To research and test your solutions we will provide you with technical tools & infrastructure and connect you with healthcare providers in our network.

As a privacy-focused company in a sensitive sector, we focus on open-source frameworks and 100% European (cloud) infrastructure. Your research and solutions will need to work within a Python based environment, using mainly open source technologies and frameworks. You will get access to AI tools for coding assistent and analysis.
