Culture

At Antares we like to specifically tie each role to our founding documents set of valueshere are the top five cultural values we think you should believe at your core to be successful:

• Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities conflicting policies perverse incentives and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. If you want to be certain then you are apt to be obsolete. Over-optimizing the components often degrades the system

• Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle

• Be Unconstrained by Convention - Our only limits are the laws of physics. Many even experts will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies by definition must accomplish the seemingly impossible. If it were easy it would have already been done. Never shy away from a solution because it has never been tried before and never choose to do something because thats how its always been done

• Go Where the Work Is - Never miss a chance to meet a customer user or stakeholder face to face even if that means hopping on a plane. If you cant make it find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere but we believe teams are built in person and aim to maximize our time together

• Operate in the Grey - Embrace nuance in pursuit of truth. Question every fundamental assumption
