As you apply for this role, we would like to give you some insights into our company culture and organization. At Sono Motors, we replace the traditional employer-employee relationship with a partnership at eye level.  When people transition from large organizations to Sono, we sometimes hear that they miss certain services, support, and infrastructure. We invite you to address these gaps with us. We see you as a creator of our company, not someone who only shows up to do their job. At Sono Motors, you take matters into your own hands, and you will achieve the desired impact. Our founders and CEOs will work alongside you, and together with the entire Sono team, you will lead our organization. We expect you to take the initiative, contribute to our organizational development, accept imperfection, and communicate transparently. We call this #staysono; this is our culture.
