We Face Fear Together

Our days are filled with doubt and fear. We are doing big, scary things on the cutting edge of technology – we should be scared! We value fear for being a great equalizer and know it puts us in the position to support one another. We also know change begins with the right action in the face of fear. Just like a diamond in the rough, we know there is opportunity on the other side. Fear is not a barrier. It is a motivator for action. We’re not afraid to fail — we’re afraid of not trying.

Luster is an equal-opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
