About the role:

As a Machine Learning / Software Engineer, you will have the opportunity to build a secure application for collaborative federated machine learning. This product, called Connect, enhances the collaboration between data experts (e.g., medical expert, data engineer) and data scientists across multiple data centers. Connect makes it possible to train a machine learning model across multiple data centers storing highly sensitive data (federated learning). For more details, have a look here!
Connect is part of the Data Platform, a fast growing team composed today of 50 people, which secures access to rich multi-modal data at scale to enable discovery and development of new treatments, internally and in collaboration with pharma partners.

  • Owkin is a great place to work. Unfortunately, being a coveted workplace means we are vulnerable to recruitment phishing scams. We urge all job seekers and candidates to be wary of potential scams. Most of these have individuals posing as representatives of prominent companies, including Owkin, with the aim of obtaining personal, sensitive, or financial information from applicants. These scams prey upon an individual’s desire to obtain a job and can sometimes “feel” like a genuine recruitment process. Some red flags are identified below. Should you encounter a recruitment process that claims to be for Owkin but is not consistent with the below, please do not provide any personal or financial information:
  • Legitimate Owkin recruitment processes include communication with candidates through recognized professional networks, such as LinkedIn. However, further 
  • communication is always through an official Owkin email address (from the domain), over the phone or though Recruitment platforms (WelcomeKit,,, Fifty Talent or Hiresweet);
  • Legitimate Owkin recruiters will not solicit personal data from candidates during the application phase including, but not limited to, date of birth, social security numbers, or bank account information;
  • Legitimate Owkin interviews may be conducted over the phone, in person, or via an approved enterprise videoconferencing service (such as Google Meets or Highfive). They will never occur via Signal, Telegram or Messenger
  • Legitimate Owkin offers of employment are based on merit and only extended once a candidate has interviewed with members of the hiring team. Offers will be extended both verbally and in written format. Owkin may request some personal information to initiate the hiring process, but this will be through protected means.
