Join Our Team as a Senior .NET Backend Developer

Are you ready to take part in the revolution of smart access technology? Join us—an innovative company that has built smart lock devices from the ground up and is on the path to becoming a global leader in the industry. You’ll become part of a highly experienced, self-managed backend team focused on expanding and improving the backend services behind our mobile and web apps, as well as smart home integrations.
