At HeyJobs, we believe that diversity and inclusion is key to creating a culture that attracts the best talent and ultimately leads to achieving our vision. Fostering this starts with hiring — therefore we do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, or any other aspect that makes you, you. Quite the opposite, we hold this as one of our core values in #teamwork and are explicitly not hiring anyone who does not respect this.

Our purpose at HeyJobs is to enable everyone to find the right job to live a fulfilling life. To achieve this, we are bringing Predictable Hiring™ to volume recruitment. Using machine learning & state-of-the-art tech, we matched over 500'000 jobs with suitable candidates and thereby improving lives at scale. By 2020 we aim to raise this number to 1 million. To date, we have raised over 15M$ in funding and are always looking to add great people to our team of 130 in the heart of Berlin. Our teams bring experiences from companies and universities like Google, McKinsey & Company, Siemens, MIT, Stanford, LSE, University of Oxford, etc. into their daily work and like to share them with you.
