Architecture and engineering firm designing mission-critical infrastructure

Architecture and Planning Chicago, Illinois 201–500 employees Founded 1999 Privately Held

LJC is a full-service architecture and engineering firm serving life sciences, data center, and mission-critical facilities sectors. The tech stack reveals a heavy emphasis on building information modeling (Revit, AutoCAD, Navisworks) paired with industrial control systems (SCADA, BMS, PLC, HMI, Ignition) — a combination that signals deep integration of design and operational technology. Active projects cluster around life sciences manufacturing, fire protection, electrical systems, and real-time monitoring, while the senior-heavy hiring mix (87 of 112 open roles) reflects demand for experienced engineers rather than entry-level staff.
