Erina — Controls Engineer

Lead I&C engineering for gas-turbine modernization and upgrade projects. Developed PLC/DCS logic diagrams, I/O lists, loop drawings, and control narratives per client specs. Designed and reviewed AC/DC circuits, MCC interfaces, and panel schematics using AutoCAD Electrical. Directed panel fabrication, wiring verification, and FAT/SAT for turbine and BOP systems. Ensured compliance with ISA, ANSI/NEMA, NFPA, AGA, and site safety standards. Managed vendor selection, procurement specs, and technical bid evaluations. Supported on-site commissioning

Designed and implemented PLC-based ground-systems control logic for cryogenic and propellant systems. Programmed GuardLogix PLCs and FactoryTalk SE/ME HMIs for GN₂, GOX, GH₂, and H₂O₂ distribution. Developed reusable code libraries (AOIs, GFX, ACDs) reducing scan time and debug cycles. Built and maintained HIL simulation environments to validate flight/ground control integration. Authored Python utilities for automatic configuration, diagnostics, and calibration management. Supported launch operations, redundancy testing (SIL 2), and safety-system validation.

Engineered PLC/HMI control systems for automotive body-in-white and welding lines (Ford, Jeep, Nissan, Volvo). Programmed Siemens Step 7 and Rockwell RSLogix 5000 systems with SCADA interfaces (FactoryTalk SE/ME). Designed panel layouts, I/O schematics, and network architectures (Profinet, EtherNet/IP). Directed commissioning teams during installation, debug, and startup of production lines. Improved system cycle times by > 20 % through code optimization and task scheduling. Delivered training programs for technicians and junior engineers on controls best practices.

Service & Systems Engineering Led after‑sales service support and preventative maintenance for electrical/automated equipment and medical/laser devices. Designed system modifications; delivered end‑to‑end builds; provided technician/engineer training and customer presentations. Performed PLC programming (RSLogix, Step7, HMI); network diagnostics and wireless topology updates; enforced inspection policies.
