Job Applications (Ashby and Google Workspace)
Nature and Scope of Processing
We use Ashby, Inc. to manage job applications and our recruitment process. Our role pages link to application forms hosted by Ashby. When you open an application form, your browser connects to Ashby, which receives technical information such as your IP address and browser information. When you apply, your name, email address, CV, links to profiles or work, answers to application questions, and any other information you provide voluntarily are transmitted to Ashby and made available to our hiring team.
Recruitment correspondence is received and processed through Google Workspace, a service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. This correspondence may also be stored in Ashby to manage the same recruitment process. Please submit applications through the application form for the relevant role.
We process this data solely for the purpose of conducting the application and selection process. It is not passed on to third parties for other purposes without your consent.
Purpose and Legal Basis
The legal basis for processing your applicant data is the initiation or establishment of an employment relationship in accordance with Art. 6(1)(b) GDPR and Section 26(1) BDSG. Insofar as you voluntarily provide us with information beyond this, the processing is carried out on the basis of your consent in accordance with Art. 6(1)(a) GDPR.
Following an unsuccessful application, limited retention to establish, exercise, or defend legal claims is based on our legitimate interests under Art. 6(1)(f) GDPR.
Transfer to Third Countries
Ashby is based in the USA, and applicant data may be processed there or by its sub-processors. Information about Ashby's processing and international transfers is available in Ashby's privacy policy. You can contact us to request information about the safeguards applicable to your applicant data.
When using Google Workspace, personal data may be transferred to servers of Google LLC in the USA. Google LLC is certified under the EU-U.S. Data Privacy Framework (EU-U.S. DPF); the transfer to the USA therefore takes place in accordance with Art. 45(1) GDPR on the basis of the adequacy decision of the European Commission. Standard contractual clauses (Art. 46(2)(c) GDPR) are used as an additional safeguard.
Storage Period
Your applicant data is stored for the duration of the application process. If no employment relationship is established, we delete it no later than six months after you receive our rejection or withdraw your application. Longer storage requires a separate basis, such as your explicit consent to a talent pool, a statutory obligation, or an ongoing legal claim. For more information, please see Google's privacy policy: https://policies.google.com/privacy.
