GrayMatter builds data and control-system integration for manufacturing and utility operations, with a tech stack anchored in Rockwell, Siemens, and Schneider Electric PLCs alongside SCADA, HMI, and MES platforms. The company is heavily engineering-focused—24 of 33 open roles are engineering—and security (4 dedicated hires) reflects a consistent internal pain around OT/IT bridging and cybersecurity risk. Active projects span MES implementation, control-system design, and OT security architecture, signaling a shift from reactive integrations toward proactive digital transformation and threat mitigation.
