Senior Frontend Developer

After two years of intense AI research and development at Ecole Normale Superieure and Ecole Centrale Paris, HrFlow.ai was founded in June 2016 to solve the labor market and employment challenges at scale using the latest innovations in AI. Having developed a proprietary AI and workflow technology from the ground up that unifies HR data silos, identifies the right candidates for the right jobs without bias, and automates it all, HrFlow.ai has already gained traction with over +1,000 clients, large and small.

HrFlow.ai raised an initial seed round of 2.3M$ in 2018 from some of the most successful technology entrepreneurs in Europe and the United States, including Xavier Niel (Free Telecom & Station F), Dominique Vidal (Index Ventures), Romain Niccoli (Criteo & Pigment), Jean-Baptiste Rudelle (Criteo), Franck Le Ouay (Criteo & LIFEN), Thibaud Elzière (Fotolia & e-Founders), and has since self-funded its growth. We love AI engineering, problem-solving, and business. Join our diverse team and help us build the next chapter of our exciting growth!
