Senior Frontend Engineer

At 12traits we believe the path to a better future lies in unlocking the true potential of humankind. We do this through harmonizing human behavior data with psychological trait sets, leveraging a multitude of scientifically valid data perspectives that allow us to understand human beings more deeply and sustainably than ever before: ushering in a new era of personalized experiences, starting in gaming, optimized for human potential and health.

Elevating the human experience is at the core of everything we do. That core is communicated through design and our fundamental passion for creating next level user experiences. As a frontend engineer you’ll work closely with visual design, UX design and research, as well as backend engineering to let graphic design, iconography, typography, color, space and texture come to life in interfaces that are awe-inspiring and smile inducing. 

We believe that helping companies to optimize experiences to be more human-centered should also be beautiful, delightful, and highly useable for them too. Leveraging human-centered and visual design principles, you’ll ensure that the aesthetic magic is translated into every aspect of our product and web experience.
