- Develop and modify detailed CE&I designs to resolve commissioning‑led issues.
- Check detailed design outputs and design changes for technical integrity and compliance.
- Ensure design changes meet functional, safety and business needs.
- Interface effectively with commissioning teams (primary interface); other engineering disciplines; site operations (as required).
- Support and mentor early‑career engineers within the design team.
- Maintain high standards of written and verbal technical communication.
Qualifications
- Minimum HND (or equivalent) in a relevant engineering discipline.
- Incorporated Engineer (IEng) or equivalent professional registration.
Experience
- Minimum 5 years' experience delivering as a Senior CE&I Design Engineer.

- Willingness to work minimum 3 days per week on plant.
- Willingness to support and develop junior engineers.
- Must hold or be eligible for SC clearance.
- 7+ years' experience at senior level.
