Karmak builds Fusion, a business management platform purpose-built for the heavy-duty trucking industry across dealerships, service shops, and rental operations. The tech stack is firmly rooted in .NET and Windows infrastructure (VB.NET, C#, SQL Server, Azure, WinForms), with active pain points around legacy system transition and data migration suggesting the company is managing a mature installed base while modernizing internally. Current hiring spans engineering, data, and support roles—a mix consistent with both platform maintenance and customer success scaling.

About Karmak

Karmak has operated since 1981 as the primary software vendor to the heavy-duty trucking industry. Their flagship product, Karmak Fusion, serves thousands of locations globally—truck dealerships, trailer dealerships, service shops, aftermarket distributors, and lease/rental operators. The company operates from Carlinville, Illinois, with a US-based support organization. Revenue streams derive from platform licensing and implementation services; customer stickiness is high given deep vertical integration into dealership operations and high switching costs.
