• Lead or support continuous improvement initiatives (Lean, Six Sigma, OEE improvement).

Control Systems Engineering

• Develop and maintain control narratives, functional specifications, and logic diagrams.
• Specify, install, and troubleshoot process instrumentation and control hardware.
• Support startup, commissioning, and validation of new or modified control systems.
• Monitor controller and loop performance using DCS and historian data to identify and implement control improvements
• Partner with operators, process engineers, and maintenance to develop and deploy improved control strategies
• Provide control room oversight during implementation of controller optimization, loop tuning, and control logic changes
• Provide instrumentation and controls engineering support including completion of instrument specification sheets

Operations Support & Troubleshooting

• Provide day‑to‑day technical support for control systems and process upsets.
• Collaborate with operations and maintenance to resolve control, instrumentation, and automation issues.
• Implement alarm management and control system reliability improvements.
• Maintain system documentation, backups, and configuration control.
• Own and maintain the plant Alarm Management Program in accordance with site standards and best practices
• Maintain and continuously improve the alarm management database to reduce nuisance alarms and improve operator effectiveness

Capital Projects & Collaboration

• Participate in projects from concept through commissioning by providing DCS and controls support for capital and non-capital projects
• Work with cross‑functional teams including process engineering, IT, quality, safety, and vendors.
• Ensure control system designs meet operational, safety, and cybersecurity requirements.

Safety, Quality & Compliance

• Support process safety activities including PHA, MOC, and safety interlocks.
• Ensure control systems comply with applicable regulatory and company standards.

Support regulated environments (e.g., FDA, EPA) where applicable.
