Careers

Quantum Brains believes that building a team starts with recruiting outstanding individuals. We are constantly looking for talented and passionate candidates driven to excel in their performance. Our pursuit of excellence results in collaborating with exceptional professionals who share the same passion for what they do.

We have incredibly bright employees, with backgrounds ranging from mathematics and physics to computer science and biology. Diversity helps us to accomplish ambitious tasks in a flexible manner and see what others in the industry don't.

Personnel Selection

We strive to minimise the impact of human factors, including potential errors by recruiters and hiring managers. That is why we prioritise test assessments over lengthy interviews. Our belief is that well-compiled online tests сontribute more to impartial and unbiased candidates’ assessment than numerous exhausting interviews. In addition, tests are more engaging and less stressful than the case studies and tasks typically used during an interview.

Mentorship

We train our new hires primarily through one-on-one mentoring. New employees are assigned to a project where they work closely with an experienced professional who can help them through the initial learning curve and provide sound and reasonable feedback.
