Software Developer – ACTIN team

Exciting Opportunity for Software Developers – Join the ACTIN-team at Hartwig Medical Foundation in Amsterdam! 

Are you passionate about using your software development skills to make a significant impact on cancer treatment? Hartwig Medical Foundation invites you to be part of our innovative ACTIN-team, developing the groundbreaking ‘Algorithmic Cancer Treatment Initiative’ (ACTIN) system. Our mission is to revolutionize cancer treatment decision-making, empowering doctors and patients to collaboratively choose the best possible treatments. 

Why do we want to deploy the ACTIN system?

  • To find the best treatment for a patient with (metastatic) cancer a data-driven approach is necessary. We’ll build an algorithm to make this happen.  
    • The variability in treatment plans between hospitals in the Netherlands should be eliminated (no matter which hospital you visit, you have access to the same data to generate the best treatment plan and of the best quality). For example, ACTIN will gather all relevant trial and treatment options across the Netherlands. These are displayed, together with relevant information, so that nothing can be missed. 
    • As a next step, we should be able to personalize the treatment plan for each patient. 
      • Compare the patient to patients that are already seen (patients-like-me and comparison to study cohorts in literature) 
      • Predict personalized response to treatment options 
  • We’ll give clinicians/doctors the best tools to efficiently decide the best treatment options for their patients. 
    • Complete (ie. includes all data that is needed for decision-making)
    • Fast (turn around time in days, end-to-end automated)
    • Easy to use
    • Scalable (to be able to handle growing/aging population)

Within Hartwig, we have a dedicated ACTIN-team, consisting of both software engineers and clinical data analysts.

What Are You Going To Do? 

  • Collaborate with software development teams in partner hospitals to enhance ACTIN’s data infrastructures. 
  • Drive automation within ACTIN, working closely with clinicians and developers to optimize processes. 
  • Design and implement a robust CI/CD pipeline, ensuring reliable and seamless upgrades. 
  • Keep up-to-date with the latest software engineering developments and proactively experiment with new technologies, tools and methodologies. 

Our Ideal Candidate

  • You have a Master’s degree in Software Engineering or a related field. 
  • You have a minimum of 1 year of experience in software development. 
  • You have a strong understanding of software development principles, version control, agile methodology, and efficient code writing practices. 
  • Experience with Java or Kotlin is a plus as well as knowledge of containerization and cloud platforms. 
  • You are able to coordinate projects across teams and organizations successfully. 
  • You are motivated to improve cancer patient care and have a keen interest in oncology, algorithms, and data analysis. 
  • You easily adapt in a changing environment, you have a critical eye for quality and you give constructive feedback. 
  • Proficiency in Dutch (both written and spoken) is a requirement. 

What We Offer You

  • Engaging and entrepreneurial work environment where your ideas are valued. 
  • Opportunities for personal and professional growth in a fast-paced, innovative setting.
