What HMS Co. LLC does
HMS Co. LLC is a Troy, Michigan-headquartered engineering services firm founded in 1960 by WWII veteran Captain Hugh Mac Sofy to provide engineering support to U.S. manufacturers. Since 2010, the company has operated as a subsidiary of Utica Enterprises, a diversified industrial conglomerate. The firm specializes in automotive body-in-white (BIW) welding robotic work cell engineering, with a primary customer base anchored on General Motors and additional exposure to Stellantis.
The company's core offerings include process engineering, mechanical design, simulation, and system layout engineering, executed using the Siemens Tecnomatix suite (Process Designer / Process Simulate, NX, FactoryCAD, Team Center) and AutoCAD. Service engagements span the full engineering lifecycle — from process inception through virtual validation and final installation and run-off at customer facilities — and include the design of specialized geo fixtures (engine cradle, body side, dash, hood roller hem, hinge pillar, motor compartment, rad support, etc.) for automotive body assembly.
HMS operates a project-based professional services model, delivering work through direct enterprise engagement with automotive OEMs. Engineers are deployed at customer facilities on long-term direct-hire-style assignments. The firm employs 51–100 people, serves only the U.S. market, and does not publicly disclose pricing or revenue. The go-to-market motion is direct enterprise field sales, supported by a company website, an active careers page, and a contact form for project inquiries.
