What Systems Interface does
Systems Interface, Inc. is a Mukilteo, Washington-based industrial control systems integrator founded in 1984 by Thor Bussinger. The company designs, engineers, and commissions custom automation solutions — PLC/HMI programming (primarily Rockwell/Allen-Bradley, plus Siemens, GE, and Modicon), SCADA systems, drive systems and motion control, and legacy migrations — for industrial and government customers across six primary verticals: aerospace, food & beverage, marine, infrastructure, power generation, and water/wastewater. Named customers include Boeing, Blue Origin, SpaceX, NASA, the U.S. Air Force, NOAA, Seattle City Light, the Department of Energy's Hanford site, Washington State Ferries, WSDOT, King County, Markey Machinery, McAllister Towing, HaiSea Marine, and KAT (Soo Locks Phase 3).
The company's core technology stack is anchored by a Rockwell Automation Gold System Integrator partnership (including Low Voltage Drive, PlantPAx, Visualization, Control System, and Optix Data Platform badges), in-house UL 508A and UL 698A certified panel fabrication across a 10,000 sq. ft. shop with CNC machining, and specialized products such as proprietary NexGen Controls for marine deck machinery winches and dual 6,000-gallon glycol-cooled liquid cream yeast systems with integrated CIP for industrial bakeries. Supporting offerings include custom MES built on MS-SQL/C# with Ignition, FactoryTalk View SE, or Siemens visualization, Cognex machine vision for warehouse traceability, and OT cybersecurity architecture aligned with ISA/IEC 62443.
Systems Interface generates revenue through project-based professional services contracts (engineering design, integration, commissioning, multi-discipline turnkey delivery, field service, and same-day emergency response), complemented by hardware sales from its certified panel fabrication shop (over 1,000 panels produced and shipped per year). Go-to-market is engineering-led enterprise field sales, supplemented by Rockwell Automation partner referrals, content marketing via case studies, and direct engagement at industry events; pricing is quote-based and project-specific. The firm is privately held, founder-managed in spirit, self-funded with no disclosed outside investment, and led by a long-tenured executive team — CEO Scott deMers (35 years), President Rob Schommer P.E. (31 years), VP of Sales Tim Rogers (35+ years), and VP of Engineering Curt Plett (30 years).
