Research Scientist I

HeartBeat.bio AG (HBB) has built a highly scalable human organoid and AI-supported drug discovery platform for developing first-in-class drugs for heart failure faster, less costly and with a higher probability of success in clinical trials. Our core technology is based on the world's first self-organizing heart-chamber-in-a-dish models (Cardioids), which resemble the human physiology of the different compartments of the heart while allowing for the cost-efficient and large-scale in vitro analysis of crucial parameters associated with cardiac diseases. We believe our Cardioid Drug Discovery Platform and our animal-free, human-centric approach have the potential to revolutionize the current cardiac drug discovery paradigm.

We work in a dynamic and collaborative environment at the Vienna BioCenter (VBC) and are looking for highly motivated candidates who share our excitement for human (cardiac) organoids and making a difference in the lives of heart failure patients. Currently, we are seeking a Research Scientist with a strong interest in assay development and optimization, high-throughput screening, and imaging. Since we are a start-up with an agile working environment, we expect the candidate to be flexible and potentially work in multiple teams with changing responsibilities and tasks.

Candidates should:

  • Have completed a Master’s degree (or equivalent) in the life science fields
  • Have iPSC or ESC cell culture experience (required)
  • Experience with phenotypic high-content screening methods or gene editing approaches is a plus
  • Strong adherence to good laboratory practices, with excellent attention to detail and accurate record-keeping
  • Have excellent communication and organizational skills
  • Enjoy working in cross-functional teams consisting of scientists and data scientists
  • Willingness to adapt schedules based on time-sensitive assays and varying workloads

Excellent English is required since we are working in an international scientific environment. German language skills are a plus, but not mandatory.

The annual gross salary is € 40,000 or higher, depending on qualification and experience, for full-time employment (40h/week). If you’re excited about joining our dynamic start-up team, please submit your CV, a letter of motivation, and the names and contact details of two references to careers@heartbeat.bio. Please use “Research Scientist I” as the subject line of your email.

We look forward to hearing from you.
