  • Select, integrate, and troubleshoot process instrumentation (e.g., flow, pressure, temperature, gas analysis)
  • Diagnose and resolve issues in field wiring, I/O signals (analog/digital), and industrial communication networks
  • Provide hands-on support, including working within electrical enclosures, validating signals, and commissioning control systems
  • Support automated data collection, reporting systems, and integration with local networks

What Makes You the Right Fit
  • 7+ years as an automation and/or controls integration engineer in an industrial or R&D setting.
  • B.S. degree in Electrical Engineering, Mechanical/Controls Engineering, Computer Science, or a related field; equivalent industry experience may be considered in lieu of a degree.
  • Development of non-Ladder Logic PLC automation systems to control existing processes and field instruments.
  • Hands-on experience with electrical system design, including panel layouts, I/O architecture, and applicable standards (UL 508A, NFPA 70E).
  • Safety oriented approach to system design and control logic.
  • Knowledge and experience implementing and managing custom SCADA and MES.
  • Understanding of industrial communication protocols (e.g. OPC, Modbus, serial communication).
  • Experience using SQL for database updating and retrieval.
  • Excellent record keeping and attention to detail.
  • Team player with excellent written and verbal communication skills.
  • Ability to work independently in a fast-paced, evolving R&D environment.

How Would You Stand Out?
  • Strong background in panel building and systems integrations.
  • Familiarity with natural language query (NLQ) and AI-enabled analytics platforms.
  • Proficiency with data visualization tools such as Spotfire and statistical software such as JMP.
  • Experience with database development and management.
  • Hands-on troubleshooting experience within electrical enclosures.

Why Choose Us?
  • Competitive Benefits (US): Our benefit package includes medical, dental, vision, 401(k), vacation, holidays, 16 weeks paid parental leave (maternity and paternity), and an annual bonus plan. IFF was also recognized by Newsweek as one of America's Greatest Workplaces for Perks & Benefits.
