Roche, Indianapolis, IN
Controls Engineer | Sept 2024 – Present
Designed and programmed Siemens S7-1500 PLCs using TIA Portal and IEC 61131-3 (Ladder & Structured Text) to automate high-speed Accu-Chek test strip production lines.
Tuned PID loops for reagent dispensing and temperature-controlled curing ovens, achieving tight process control and quality consistency.
Integrated high-resolution encoders, capacitive sensors, and G120/S120 drives via Profinet for coordinated motion control in web handling and strip rejection systems.
Developed WinCC HMI interfaces with recipe management, guided troubleshooting, and dynamic fault visualization to support cleanroom operations.
Deployed Ignition SCADA dashboards for real-time OEE, alarms, and batch traceability. Built OPC UA links to PLCs and SQL servers to support KPI visualization and shift performance.
Automated data reporting with Python scripts, enabling MES integration, batch traceability, and FDA 21 CFR Part 11 compliance.
Collaborated with IT to implement SCADA cybersecurity using network segmentation, firewall rules, and RBAC policies.
Resolved packaging line sensor alignment and pneumatic timing issues, reducing false alarms and improving machine uptime.
Participated in FAT/SAT testing and authored IOQ documentation under GMP and GAMP 5 validation procedures.
Peterbilt, Denton, TX
Manufacturing Controls Engineer | June 2023 – July 2024
Programmed Allen-Bradley ControlLogix systems using Studio 5000 to automate truck assembly processes including cab, chassis, and engine integration.
Developed sequencer logic and takt-time-based cycles, integrating torque tools, scanners, and hoists over EtherNet/IP for VIN-based verification.
Designed FactoryTalk View SE dashboards with real-time build steps, torque validation, and operator fault alerts.
Implemented OPC UA communications using Kepware for centralized SCADA/MES integration and line-side data capture.
Troubleshot torque tool signal failures due to loose I/O connections and added heartbeat-based fault detection logic.
Contributed to ISO 13849-based safety circuit implementation for engine drop stations using interlocked hoists and positional sensors.
Yokogawa Electric, Hyderabad, IN
System Engineer | July 2020 – Dec 2022
Automated municipal water treatment plants using Allen-Bradley ControlLogix PLCs and Yokogawa FAST/TOOLS SCADA systems.
Programmed pump sequencing, chlorine dosing, and flow control logic based on field sensors, transmitters, and turbidity analyzers.
Designed safety logic for tank overfill, low-flow detection, and backwash protection aligned to ISO 24512 and local water utility standards.
Integrated SCADA systems with OPC UA, Modbus TCP/IP, and smart analyzers for centralized dashboard visibility and event tracking.
Used Python to generate production summaries, identify sensor dropouts, and populate SQL-based compliance logs.
Tuned PID loops for clear well balancing during peak flow conditions, reducing overflow events and enhancing network stability.
