Senior Automation & Controls Engineer
About The Position
SQ4D is a construction technology company developing and deploying advanced robotic systems for concrete 3D printing. Its Autonomous Robotic Construction System (ARCS) combines large-scale robotics, automation, software, motion control, and material delivery systems. The Automation & Controls Engineer will help develop, integrate, and improve the electrical, software, motion-control, automation, and control systems used throughout SQ4D's construction 3D-printing technology. The role works across hardware and software, including PLC programming and industrial automation, Duet development, motion control, machine communications, sensor integration, and software architecture. The engineer will help build systems that enable a large-scale robotic construction printer to move, communicate, and operate autonomously. Work may include developing motion-control capabilities, improving Duet-based printer systems, integrating PLC-controlled equipment, creating diagnostic tools, improving machine reliability, and developing future versions of ARCS.
