Sr. Mechanical Engineer

Challenge Yourself and Impact the Future!

The position is responsible for developing and implementing all process control systems and automation systems for new machines and processes, designing and developing process controls, automation and data acquisition systems. This position will own the entire controls stack—from sensor selection and safety‑instrumented functions to PLC/DCS programming, and data—while partnering closely with chemical‑process engineers, production, EHS, and R&D teams to deliver repeatable, world‑class manufacturing performance.

• Lead front‑end engineering and detailed design for new equipment, processes, reactors, wet benches, blending, and packaging lines.
• Translate PFDs/P&IDs into I/O lists, control narratives, and cause‑&effect matrices.
• Specify and configure PLC/DCS/HMI/SCADA platforms (Rockwell, Siemens, Delta
  
  V, Opto 22 etc.) and industrial networks (Ether Net/IP, PROFINET, Profibus, Modbus).
• Develop compliant code, sequential/batch logic, alarm strategies, and historian interfaces.
• Lead FAT/SAT, startup, and on‑site commissioning; troubleshoot to root cause and drive continuous improvement.
• Perform LOPA/SIL verifications, design safety‑instrumented functions, and ensure compliance with NFPA 70/79, UL 508A, and IEC 61511 in flammable, corrosive, or cleanroom environments.
• Deploy data‑collection and visualization tools (OSI PI, SQL, Python) to monitor KPIs, reduce downtime, and increase OEE.
• Prepare timelines for process control and automation projects.
• Manage automation work streams on CAPEX projects—scope, budget, schedule, vendor coordination, and documentation.
• Promote best practices in code management, testing, and change control (ISA‑95/GAMP).
• Stay current in process control technology to resolve problems using solutions that involve new techniques, technologies and concepts.
• Developing and implementing process control systems and automation systems for new machines, processes and facilities.

• Bachelor’s degree in Automation Engineering or Electrical Engineering; MS degree preferred.
• 8+ years of hands‑on experience designing and commissioning PLC/DCS/HMI systems in batch or continuous chemical plants.
• Proven expertise with at least one major platform (e.g., Rockwell Control Logix, Siemens PCS7, Emerson Delta
  
  V, ABB 800xA, Opto 22 or Honeywell Experion).
• Strong grasp of instrumentation, process‑control theory and hazardous‑area classifications (Class
  
  I/Div2, ATEX).
• Knowledge of Python, C/C++, or other scripting languages for automation.
• Familiarity with vision systems, servo drives, and safety PLCs.
• Certifications such as TUV Functional Safety Engineer or Rockwell/Siemens certifications.
• Demonstrated success leading multi‑disciplinary project teams and external automation integrators.
• Excellent analytical, troubleshooting, and written/verbal communication skills.
