temperature, level, pH).

• Basic understanding of electrical control panels and industrial networking concepts.

Preferred Qualifications

• Experience in fermentation, biotechnology, food, pharmaceutical, or chemical manufacturing.

• Hands-on experience with PLC platforms such as Allen-Bradley, Siemens, ABB or similar, and

HMI/SCADA software such as FactoryTalk, AVEVA InTouch, or equivalents.

• Familiarity with process instrumentation, industrial communication networks (e.g., Ethernet/IP,

Profibus, Modbus), and OT cybersecurity best practices.

• Experience with data collection tools, historians, or basic data analytics (e.g., SQL, dashboards)

to support decision-making.

Technical Skills

• PLC programming, troubleshooting, and commissioning.

- HMI/SCADA configuration, alarm management, and user interface design.
