User Researcher (m/f/d) | Legal AI Tech Start-up | Remote

The AI startup Xayn develops Noxtua, Europe’s first sovereign Legal AI. Noxtua helps lawyers analyze and draft legal documents and research legal questions while being legally competent and compliant. Hosted in the EU, Noxtua meets high standards of confidentiality in handling client data, professional secrecy (e.g. Section 203 German Criminal Code, Section 43e German Federal Code for Lawyers), and European data protection. Noxtua is powered by specialized proprietary AI models. The models are trained with high-quality legal data provided by the Legal AI Alliance which the tech startup Xayn initiated with the international business law firm CMS. This makes Noxtua the secure, independent, and specialized European Legal AI.

The Berlin-based AI company Xayn was born out of research at Oxford University and Imperial College London by Dr Leif-Nissen Lundbæk and Professor Michael Huth. Founded in 2017, Xayn’s academic vision remains, with a workforce comprised of approx. 30% PhDs. The startup has received investment funding of 19.5 million EURO from Global Brain Corporation, KDDI Open Innovation Fund, Earlybird, and Dominik Schiener.
