Senior Rockwell PLC / Automation Engineer – Horizon Controls Group – Leiden

Jobid=618999444016803743 (0.0992)

Job Summary

Horizon Controls Group is seeking experienced Senior Rockwell PLC / Automation Engineers to support the design, development, and delivery of advanced manufacturing automation systems within a highly regulated pharmaceutical environment.

This position is focused on engineers with strong design-level automation expertise, rather than execution-only experience. The successful candidate will play a key role in architecting and developing automation solutions for complex manufacturing systems, working within Lilly’s proprietary automation environment rather than traditional off-the-shelf SCADA platforms such as Ignition, PlantPAx, or DeltaV.

The role requires a highly technical and adaptable automation professional capable of working closely with global engineering, process, manufacturing, CQV, and digital teams to deliver scalable, compliant, and high-performing automation solutions supporting next-generation pharmaceutical manufacturing.

Key Responsibilities

  • Lead the design and development of Rockwell PLC-based automation solutions for pharmaceutical manufacturing systems and equipment.
  • Develop and modify PLC logic, control strategies, functional specifications, and automation architectures within Lilly’s proprietary automation framework.
  • Support automation system lifecycle activities, including design reviews, testing, commissioning support, troubleshooting, and operational readiness.
  • Collaborate with process engineers, manufacturing teams, CQV, MES, and digital engineering functions to ensure automation solutions align with operational and compliance requirements.
  • Work within a non-standard Lilly automation architecture, requiring flexibility and the ability to quickly understand custom-built manufacturing control systems.
  • Participate in automation design workshops, risk assessments, and technical reviews to ensure robust and scalable system designs.
  • Support integration activities between PLC systems, MES platforms, historians, databases, and enterprise systems.
  • Develop and review technical documentation including URS, FDS, SDS, IO lists, network architecture diagrams, test documentation, and change controls.
  • Ensure compliance with GMP, GAMP5, data integrity, and cybersecurity standards throughout the automation lifecycle.
  • Provide technical leadership and mentorship to junior engineers and project teams.
  • Support FAT, SAT, commissioning, IQ/OQ activities, and startup support where required.
  • Troubleshoot complex automation and controls issues within live manufacturing environments.


Requirements

Required Experience & Qualifications

  • Degree in Automation, Electrical, Electronic, Mechatronic, Software, or related Engineering discipline.
  • Strong experience as a PLC / Automation Engineer within pharmaceutical, biotech, or regulated manufacturing industries.
  • Advanced hands-on expertise with Rockwell PLC platforms including ControlLogix, CompactLogix, Studio 5000, FactoryTalk, and related technologies.
  • Proven design-level experience developing automation architectures, PLC code, and control strategies — not solely commissioning or execution support.
  • Comfortable working within custom or proprietary automation architectures rather than relying exclusively on standard SCADA platforms such as Ignition, PlantPAx, or DeltaV.
  • Strong understanding of industrial automation networks, field instrumentation, and system integration principles.
  • Experience supporting manufacturing process equipment and automated production systems.
  • Familiarity with GMP environments, GAMP5, ISA-88, ISA-95, and pharmaceutical validation requirements.
  • Experience with automation testing, commissioning, and qualification activities.
  • Strong problem-solving and analytical skills in complex operational environments.

Preferred Experience

  • Experience within API, biologics, or advanced pharmaceutical manufacturing environments.
  • Exposure to MES integration, digital manufacturing, or Industry 4.0 initiatives.
  • Knowledge of serialization, batch systems, or data historians.
  • Experience working on large-scale greenfield pharmaceutical projects.
  • Familiarity with cybersecurity and OT network standards.

Key Competencies

  • Automation system design and architecture expertise
  • Strong technical leadership and ownership mindset
  • Excellent collaboration and communication skills
  • Adaptability within custom engineering environments
  • High attention to quality, compliance, and detail
  • Strong troubleshooting and root cause analysis capabilities
