Lead Engineer / Tech Lead - Ruby on Rails (all genders)

What to expect

We need you to build systems for scalable and innovative solutions with Caspar!

Caspar-Health was founded in 2016 to revolutionize the world of therapies. Currently access to medical therapies (i.e., prevention or rehabilitation) is restricted, and patients often do not get the best possible treatment for their recovery. By using Caspar-Health, digital therapy combined with personal therapeutic care, we allow patients to overcome the limited access to temporal and on-site therapy and enable them to exercise anytime and anywhere.

With Caspar, therapists create and share therapy plans with their patients, and both parties interact with each other remotely. Caspar-Health works with the most valued medical facilities in Germany.

We are looking for a highly motivated Lead Engineer / Tech Lead (all genders) to join our team in Berlin. It is an exciting time to work at Caspar because you will be the one designing how the system will work in the future.
