Contribution squad Senior Software Data Engineer

At Castor Doc we believe that people do not need to be data experts to find, understand and use data. We’ve developed a product that is plug-and-play, fun to use, and collaborative. It automates painful data governance tasks to create a centralized knowledge hub that empowers teams to easily discover, interpret, and leverage their organization's information assets.

Created in 2020, by four data lovers who experienced firsthand the pain of dealing with data, Castor Doc is already running in leading data teams at Doctolib, Deliveroo, Veolia, Vestiaire Collective, Mano Mano, Freeport McMoran, Veolia or Payfit.

Our team of almost 40 people is made of experts in their domains, sharing a common bold vision to impact companies through data. To support it, we raised a 23m€ Series A from Frst, Blossom, and accomplished Business Angels (founders of Dataiku, Zenly, Vestiaire Collective, etc).

We are seeking a skilled Software Data Engineer to join our growing Contribution Squad, working alongside talented fullstack and data engineers.
