Job Summary
Logical Systems, Inc. (LSI) seeks a highly technical MES Solutions Architect to design, build, integrate, and support advanced Manufacturing Execution Systems across industrial and regulated manufacturing environments. This role bridges OT and IT, combining plant‑floor automation expertise (PLC, SCADA, Historians) with enterprise application integration (ERP, QMS, LIMS, analytics) to deliver real‑time, scalable MES architectures. The ideal candidate can build MES applications from the ground up, understand deterministic shop‑floor communication, and design event‑driven, ISA‑95 aligned systems that support production execution, traceability, quality, and operational intelligence. Experience developing validation document stacks (URS/FRS/FS/DDS/IQ/OQ/PQ) is a significant plus.
