Why This Role Stands Out

- Investigate plant performance issues through structured investigation and root cause analysis
- Support the Engineering Manager with planning and controlling control-system and IT budgets
- Act as subject matter expert on capital projects that involve control and OT scope
- Coordinate with group-level and shared-service teams on standards, strategy, and issue resolution
- Promote a safety-first culture and ensure full compliance with UK legislation and site SH&E requirements
Requirements
- Degree in Chemical Engineering, Process Control Systems, or Instrumentation and Electronics
- Strong background with modern distributed control systems, covering both software and hardware architecture
- Familiarity with virtualised control system environments (VMware / Hyper-V), including replication and failover

- Functional safety certification to 61511/61508 for safety instrumented systems
- Working knowledge of OT cybersecurity practices and management systems
